It was the creation of a cheap PID controller. Within days I put together a PID controller for my swimming pool project, and it was a complex analog build. Unfortunately, things do not always go ...

[Harvs] hacked a cheap PID controller ... Though the project hasn’t been updated recently, [Harvs] was planning on adding an ESP8266 for remote monitoring and control. Great work [Harvs]!

Users can configure their own systems from a broad and growing selection of modules. The SIM960 analogue PID controller combines analogue signal handling with digital control, giving the user the best ...

NI claims the CompactRIO computing engine can implement multiloop analog PID control systems at loop rates exceeding 100 ksamples/sec, perform digital control loops at rates to 1 Msamples/sec ...
