Device maintains the heater temperature as close to the setpoint as possible and is pretty universal. This code, without any modifications, was used for very different heaters: makeshift heating plate ...

This project implements a closed-loop temperature control system using an Arduino-based PID controller and TRIAC-based AC power control. The system compares multiple temperature sensors (LM35, RTD, ...

A few weeks ago, I installed an automatic water heater switch to my bathroom, but it was a crude device. What I really want to do is design a universal heater driver. That basic idea can be adapted to ...

Experience — or at least education — often makes a big difference to having a successful project. For example, if you didn’t think about it much, you might think it is simple to control the ...

The front circuit board is the meat and potatoes of the device. It hosts the user interface in the form of buttons, LEDs, and a graphic LCD screen. You can also see the USB mini-b connector which ...
