Metro is our series of microcontroller boards for use with the Arduino IDE. This new Metro M0 Express board looks a whole lot like our original Metro 328, but with a huge upgrade. Instead of the ATmega328, this Metro features a ATSAMD21G18 chip, an ARM Cortex M0+. It’s our first Metro that is designed for use with CircuitPython. CircuitPython is our beginner-oriented flavor of MicroPython, and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.
Not only can you use CircuitPython, but the Metro M0 is also usable in the Arduino IDE.
At the Metro M0’s heart is an ATSAMD21G18 ARM Cortex M0 processor, clocked at 48 MHz and at 3.3V logic, the same one used in the new Arduino Zero. This chip has a whopping 256K of FLASH and 32K of RAM. This chip comes with built in USB so it has USB-to-Serial program and debug capability built in with no need for an FTDI-like chip.
- Power the METRO with 7-9V polarity protected DC or the micro USB connector to any 5V USB source. The 2.1mm DC jack has an on/off switch next to it so you can turn off your setup easily. The METRO will automagically switch between USB and DC.
- METRO has 25 GPIO pins, 12 of which are analog in, and one of which is a true analog out. There’s a hardware SPI port, hardware I2C port and hardware UART. Logic level is 3.3V
- Native USB, there’s no need for a hardware USB to Serial converter as the Metro M0 has built in USB support. When used to act like a serial device, the USB interface can be used by any computer to listen/send data to the METRO, and can also be used to launch and update code via the bootloader. It can also act like a keyboard, mouse or MIDI device as well.
- Four indicator LEDs and one NeoPixel, on the front edge of the PCB, for easy debugging. One green power LED, two RX/TX LEDs for data being sent over USB, and a red LED connected. Next to the reset button there is an RGB NeoPixel that can be used for any purpose.
- 2 MB SPI Flash storage chip is included on board. You can use the SPI Flash storage like a very tiny hard drive. When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB.
- Easy reprogramming, comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed. It can be used to load up CircuitPython, PXT/MakeCode or Arduino IDE (it is bossa-compatible)

HC-SR04 Ultrasonic Sensor
This is the HC-SR04 ultrasonic distance sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accuracy that can reach up to 3mm. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit.
There are only four pins that you need to worry about on the HC-SR04: VCC (Power), Trig (Trigger), Echo (Receive), and GND (Ground). You will find this sensor very easy to set up and use for your next range-finding project. This sensor has additional control circuitry that can prevent inconsistent “bouncy” data depending on the application.

ChronoDot – Ultra-Precise Real Time Clock – v2.1
The ChronoDot RTC is an extremely accurate real time clock module, based on the DS3231 temperature compensated RTC. It includes a CR1632 battery, which should last at least 8 years if the I2C interface is only used while the device has 5V power available. No external crystal or tuning capacitors are required.
The top side of the Chronodot now features a battery holder for 16mm 3V lithium coin cells. It pairs particularly well with CR1632 batteries. The DS3231 has an internal crystal and a switched bank of tuning capacitors. The temperature of the crystal is continously monitored, and the capacitors are adjusted to maintain a stable frequency. Other RTC solutions may drift minutes per month, especially in extreme temperature ranges…the ChronoDot will drift less than a minute per year. This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock.

RGB LCD Shield 16×2 Character Negative Display
With this in mind, we wanted to make it easier for people to get these LCD into their projects so we devised a shield that lets you control a 16×2 Character LCD, up to 3 backlight pins AND 5 keypad pins using only the two I2C pins on the Arduino. The shield is designed for Arduinos Uno. It uses the I2C pins at Analog 4 and Analog 5.
At this time, the library and shield can control the RGB backlight of our character LCDs by turning each LED on or off. This means you can display the following colors: Red, Yellow, Green, Teal, Blue, Violet, White and all off. This shield is perfect for when you want to build a stand-alone project with its own user interface. The 4 directional buttons plus select button allows basic control without having to attach a bulky computer.
Adjusting Contrast
The shield uses a character LCD with an external contrast potentiometer. The first time you use it, adjust the potentiometer in the bottom right until you see the text clearly.

Adafruit PowerBoost 500 Shield – Rechargeable 5V Power Shield
What’s a project if it’s trapped on your desk? Now you can take your Arduino anywhere you wish with the PowerBoost shield. This stackable shield goes onto your Arduino and provides a slim rechargeable power pack, with a built in battery charger as well as DC/DC booster.
Compatible with Arduino Uno basically any Arduino-pinout-shaped Arduino as only the GND and 5V pins are used. You can stack shields on top, or stack the PowerBoost on top. The PowerBoost shield can run off of any Lithium Ion or Lithium Polymer battery but we suggest our 2000mAh capacity batteries, both of which fits very nicely in the empty space of the shield. Plug in the battery and recharge it via the microUSB jack. When you’re ready to go, just unplug the Arduino from USB or the wall adapter and it will automatically switch over to shield power. Use only Lipoly batteries with protection circuitry.
The onboard boost converter can provide at least 500mA current, and can peak at 1A. There’s an onboard fuse to protect against higher current draws which could damage the boost converter or battery. The boost converter can be damaged by high current spikes and is not recommended for driving motors or robots where the stall current can cause high current spikes. It will let you turn the shield and Arduino power on/off.
Lithium Ion Battery – 3.7v 2000mAh
Lithium ion polymer batteries are thin, light and powerful. The output ranges from 4.2V when completely charged to 3.7V. This battery has a capacity of 2000mAh. If you need a larger battery. The batteries come pre-attached with a genuine 2-pin JST-PH connector as shown and include the necessary protection circuitry. Because they have a genuine JST connector, not a knock-off, the cable wont snag or get stuck in a matching JST jack, they click in and out smoothly.

E-Mentoring
E-mentoring stemmed from mentoring programs with the invention of the Internet. Mentorship is a relationship in which a certain area of expertise. Mentoring is a process for the informal transmission of knowledge, social capital, and the psychosocial support perceived by the recipient as relevant to work, career, to have greater relevant knowledge, wisdom, or experience.
This is an up-and-coming, incredibly important position. Technology has been rapidly improving, and becoming more a part of day to day you must know how to get things done on the newest technology. A technology mentor will help with technical breakdowns, advise on systems that may work better than what you’re currently using, and coach you through new technology and how to best use it and implement it into your daily life.
Individuals around the world were in survival mode, experiencing various amounts of success and frustration in adopting legally enforced virtual work as they tried to maintain business continuity in a time of personal and professional uncertainty. Adaption was critical to the success of each organization and individual. And through it all we learned that work is something that we do, not somewhere that we go.
E-Mentor Over Zoom
Here’s how E-Mentor and E-Mentee can successfully spin up virtual classrooms, participate in online classes, and use Zoom for distance Technology E-Mentor microcontrollers and robotics.
Technology E-Mentor Microcontrollers and Robotics
In technology E-Mentor microcontrollers and robotics education program whose purpose is to assist users in learning how to use parts or any other application, operating system interface, or programming tool. There are three kinds of tutorials:
- Webinars where users participate in real-time tutorial workshops remotely using web conferencing software (Zoom).
- 1 E-Mentor <=> 1 E-Mentee.
- 1 E-Mentor <=> Group E-Mentee.
- A demonstration of a process, using examples to show how a workflow or process is completed.
- Some method of review that reinforces or tests understanding of the content in the related module or section.
- Written documents, audio file and microcontrollers programming downloadable.
- Kit: Development Board, Solder Soldering Irons, Beginner Parts, Small Parts, Discrete Semiconductor, Sensor, Guidebook, Etc…
At Luc Paquin I believe that an understanding of electronics is a core literacy that opens up a world of opportunities in the fields of robotics, Internet of Things (IoT), engineering, fashion, medical industries, environmental sciences, performing arts and more. This guide is designed to explore the connection between software and hardware, introducing Arduino code and parts as they are used in the context of building engaging projects. The circuits in this guide progress in difficulty as new concepts and components are introduced. Completing each circuit means much more than just experimenting you will walk away with a fun project you can use and a sense of accomplishment that is just the beginning of your electronics journey. At the end of each circuit, you’ll find coding challenges that extend your learning and fuel ongoing innovation.
Schedule of Services E-Mentor
- Beginner: These beginner-friendly microcontrollers are easy to use and program with just a computers or laptop, a USB cable, and some open-source software.
- Intermediate: Internet of Things (IoT).
- Advanced: Robotics, engineering, fashion, medical, environmental, performing arts, etc…

Pololu Adjustable Step-Up Voltage Regulator U1V11A
This compact U1V11A switching step-up voltage regulator efficiently boosts input voltages as low as 0.5 V to an adjustable output voltage between 2 V and 5.25 V. Unlike most boost regulators, the U1V11A offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output. The pins have a 0.1 inch spacing, making this board compatible with standard solderless breadboards.
NeoPixel Stick – 8 x 5050 RGB LED
Make your own little LED strip arrangement with this stick of NeoPixel LEDs. We crammed 8 of the tiny 5050 (5mm x 5mm) smart RGB LEDs onto a PCB with mounting holes and a chainable design. Use only one microcontroller pin to control as many as you can chain together! Each LED is addressable as the driver chip is inside the LED. Each one has ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC.

EMF Meters
EMF measurements are measurements of ambient electromagnetic fields that are performed using particular sensors or probes, such as EMF meters. These probes can be generally considered as antennas although with different characteristics. In fact, probes should not perturb the electromagnetic field and must prevent coupling and reflection as much as possible in order to obtain precise results. EMF probes may respond to fields only on one axis frequency selective measurements in which the measurement system consists of a field antenna and a frequency selective receiver or spectrum analyzer allowing to monitor the frequency range of interest. Amplified, active, probes can improve measurement precision and sensitivity but their active components may limit their speed of response.
SMA Connector
PCB edge mount – SMA RF connector. Perfect for prototyping with the GPS and Cellular devices that require an antenna connection. These connectors have a female signal pin and will correctly mate with the original SMA type antennas.
Telescopic Antenna SMA – 300 MHz to 1.1 GHz (ANT700)
This ANT700 is a telescopic antenna designed for operation from 300 MHz to 1.1 GHz with a total length that is configurable from 9.5 cm to 24.5 cm. Each ANT700 is constructed of stainless steel and features an SMA male connector, rotating shaft, and adjustable elbow.
