An inexpensive Arduino-based PID controller designed in the laboratory to control the temperature, consists of hardware parts: Arduino UNO, thermoelectric cooler, and electronic components while the software portion includes C/C++ programming. • Temperature range is from -40 to 125 degree Centigrade with accuracy of ±0. PID Temperature Sampling. The library comes with a number of example sketches. osakechan shared his project notorious PID fermentation temperature control in the Adafruit Forums: Hello Adafruit people! I just wanted to share a project I’ve been working on.
