Have Some Robotic Fun with These Raspberry Pi-Powered Cars
The PiCar-S is an open source robot learning kit on Raspberry Pi that will help you learn robotics and IoT programming in an exciting way. With three sensor modules including ultrasonic obstacle avoidance, light follower, and line follower, you can develop a better understanding of how to program the car's controls. This fun, family-friendly educational experience is a whole lot more interesting than that RC car you were thinking about getting.
Use included Python code to get the car up & running
Teach the car how to avoid obstacles, follow light, & follow lines that you program
