Another great chapter from the Parallax documentation for the Board of Education shield bot kit for Arduino! Chapter 2:
In this chapter, you will use the Board of Education Shield for building and testing circuits with Parallax continuous rotation servos, resistors, and light-emitting diodes. Along the way, you’ll start learning the basics of building circuits and making the Arduino interact with them. By the end of the chapter, you’ll have a pair of servos connected, each with its own signal indicator light, and you’ll be writing sketches to control servo speed and direction.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
