After hours of operation, I noticed some defects in the pool heater driver circuit. It needs more testing ... In this experiment I am trying a far-famed Arduino PID library (PID_v1) which is simple to ...

circuit diagrams, PID controller algorithms, and full program listings and program descriptions for both the Raspberry Pi and Arduino Uno.

For example, if you didn’t think about it much, you might think it is simple ... and an Arduino. There’s also an LCD display and a FET to control the heater. The idea behind a PID controller ...

The end result is you can have the circuit simulator on the left of the screen and a Web-based Arduino IDE on the right side. But how does it work beyond the simple demo? We wanted to find out.
