A PID controller for Arduino that implements advanced features often missing from standard libraries. Designed for advanced control strategies.

"Windup" occurs when the integral term grows indefinitely while the actuator is saturated (at max limit). Standard PID calculates d(Error)/dt. This library calculates ...

AI In My PID Loops? It’s More Likely Than You’d Expect

Some wonder if AI will replace PID control loops. The reality is that, instead of replacing PID, AI is stepping in to help keep things running smoothly without upending regulatory trust. Think of AI ...

Limited PWM Frequency Range - Cannot Set Below ~500Hz

I’ve encountered a limitation when using PWM on the RP2040 with the Mbed-based Arduino core: It seems impossible to set a PWM frequency below ~500Hz. This effectively restricts the usable PWM range, ...
