DC Motor
A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.
DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor’s speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills. The advent of power electronics has made replacement of DC motors with AC motors possible in many applications.

DRV8835 Dual Motor Driver Carrier
This tiny breakout board for TI’s DRV8835 dual motor driver can deliver 1.2 A per channel continuously (1.5 A peak) to a pair of DC motors, and it supports two possible control interfaces for added flexibility of use: IN/IN and PHASE/ENABLE. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors. The carrier board has the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1 inch perfboards.
Solarbotics RM2 (High-Power Motor for GM2/3/8/9)
This high-power brushed DC motor fits in the GM2/3/8/9 series of gear motors, offering approximately 3 times the speed, twice the torque and quadruple the power-draw. Retrofitting the gear motor is easy – just remove the motor retainer strap, transfer the pinion gear, and reinstall – that’s it.

Stepper Motor
A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can be commanded to move and hold at one of these steps without any position sensor for feedback, as long as the motor is correctly sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
EasyDriver – Stepper Motor Driver
The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse. The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar.

Joystick
A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It often has supplementary switches to control various aspects of the aircraft’s flight.
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.

Serial
Used for communication between the Arduino board and a computer or other devices. All Arduino boards have at least one serial port, and some have several. Fio v3 ATmega32U4 board, Serial1 pins, 0(RX), 1(TX). On Fio v3 ATmega32U4, pins 0 and 1 are used for communication with the computer. Connecting anything to these pins can interfere with that communication, including causing failed uploads to the board. You can use the Arduino environment’s built-in serial monitor to communicate with an Arduino board. Click the serial monitor button in the toolbar and select the same baud rate used in the call to begin(). Serial communication on pins TX/RX uses TTL logic levels 3.3V . Don’t connect these pins directly to an RS232 serial port, they operate at +/- 12V and can damage your Arduino board.

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.

MicroSD Card Breakout Board+
Not just a simple breakout board, this microSD adapter goes the extra mile – designed for ease of use.
- -Onboard 5v->3v regulator provides 150mA for power-hungry cards
- -3v level shifting means you can use this with ease on either 3v or 5v systems
- -Uses a proper level shifting chip, not resistors: less problems, and faster read/write access
- -Use 3 or 4 digital pins to read and write 2Gb+ of storage
- -Activity LED lights up when the SD card is being read or written
- -Push-push socket with card slightly over the edge of the PCB so its easy to insert and remove
- -Comes with 0.1″ header so you can get it on a breadboard or use wires
To use with an Arduino, connect GND to ground, 5V to 5V, CLK to pin 13, DO to pin 12, DI to pin 11, and CS to pin 10.

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.
