An introductory tutorial for Arduinos.
This tutorial is the third installment of the Arduino Workshops
Basic Arduino Code
Now that we have the building of the cars and driving controls sorted out from the previous workshops we can now look at getting the robot to drive itself.
Below is the code for the workshop, we use 3 ultrasonic sensors mounted on the front of the car. Make sure that you change the pin numbers to match your wiring! You can always check that your sensors are working properly by reading the serial output on your computer when the bot is plugged in.
