Motor Algorithms
Making a robot go forward is easy. Making it drive in a perfectly straight line? That takes algorithms... โจ PAN'S RULE: If it's not chaotic, it's not magic! โจ
Use PID control loops to make robots drive straight, balance, and reach targets accurately.
โ ๏ธ SAFETY DIRECTIVE: We only work with safe 5V USB
power or AA/AAA batteries. NEVER plug homemade
electronics into a wall outlet or mess with mains electricity. Keep
the magic safely low-voltage!
The PID Controller
If your car's cruise control is set to 60mph, and you hit 59mph, flooring the gas pedal creates a jerky ride. A Proportional-Integral-Derivative (PID) loop constantly calculates the mathematical error to apply just the right amount of throttle.

used in everything from oven thermostats to space rockets.
