[Peter Sobey] had a solar hot water heater installed in his home ... got the urge to add a wireless display and control panel to the mix. A pair of Arduino Nanos run the show now, one of which ...

Like most, they put up with the cold — but after having a baby, [George] decided it was time ... for the heater. Now he just needed a PID library — readily available from Arduino.cc of course.

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board ... is used to delay() the program execution with the desired amount of time. In our case after the ...

If you are building Internet of Things (IoT) projects, the ability to receive real-time alerts is ... and notifications, Arduino is empowering them to have more control over their IoT devices.

But what happens if we want to control time? We can answer this question with the bare motor rotation, and a more complex software. For this project I am using the Arduino Mega 2560. First, we should ...
