This PLC adjusts the heaters (lamps), in order to control the temperature. However, the Arduino can't measure resistance directly, it can only measure voltage. PID Control with the BASIC Stamp. In my opinion, temperature monitoring accuracy can (and should) be improved. The stuff in the middle is the the algorithm that ties these together. affect cooking temperature, requiring constant vent adjustment. This post is not directly related to the DC Generator controller, but I figure it is related and relevant. If so, an easier way to do this, especially with that budget, is to look for a PID temperature controller on one of the surplus sites like All Electronics, surplusdirect, etc. You can drive the base of the transistor. It has enjoyed popularity as a purely mechanical device, as a pneumatic device, and as an electronic device.
