To this point we have controlled light, motion, and electrons. Let's tackle sound next. But sound is an analog phenomena, how will our digital Arduino cope? We will once again rely on its incredible speed which will let it mimic analog behavior. To do this, we will attach a piezo

Overview This is the first part of the 2-part project for 4-wheel drive multifunction (wireless) robot car kit. The first part covers the functionality of a robot car with its own obstacle avoidance capability using both ultrasonic sensors and infrared obstacle avoidance modules. The robot car is completely autonomous to the robot car kit owner. The robot car uses the
