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 a USB cable, a breadboard, some breadboarding wires, and the LCD you used in Chapter 4, Using Specialized Output Devices. You'll also need three standard servos. If possible, the servos should be of the same brand and make—this will help with our project.
