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 ...

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 ...

Yes, you can make a power inverter circuit that uses Arduino to generate the PWM signals and readily available N-channel MOSFETs — with some (optional) simple circuit protection and load sensing, of ...

However, if you’re just looking to catch a sandwich thief at work or a cat spilling over all you water bottles, then Make shows you how to build an alarm system with an Arduino and a USB camera.

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