In this project, we are going to build something very simple project, a temperature controlled relay that is used to turn on a dc fan. You can actually change the DC Fan to other electrical devices ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture ... apart from the module only a few external components are needed to build a ...

He further explains that, with the Arduino Uno, you can remove the reference capacitor from the circuit, and simply use the stray capacitance present in the board and microcontroller, which can be ...

The Arduwire UNO is ... for the Arduino UNO development board. This shield enables users to perform a variety of tests on cables and harnesses, including continuity, open circuits, shorts, and ...

As the regular LEDs are too small to be noticeable, you can replace them with bigger LEDs or even a light bulb (paired with a relay for the Arduino Uno). Try a toggle switch instead, so you won't ...
