What you'll need for this chapter
You'll need your microcontroller—I highly recommend the Arduino Uno for this chapter because of its compatibility. You'll also need your USB cable, a breadboard, some breadboard wires, and a 10k ohm resistor. Grab a photocell, or any other sensor you'd like to try.
You'll also need a motor that runs on 5V and a standard hobby servo that uses 5V. These can be found easily at hobby stores or on Adafruit, SparkFun, Seeed studio, and many other online shops. Check out the following section to see some of your options.
