Pressing the self-test again takes you to the switch test. Switches that are stuck on will be identified by number in the displays, like the original test. However, the PTU allows up to four stuck ...

When you’re prototyping a new project, sometimes all you need is a switch. The folks at oomlout were tired of constantly having to rewire things, so they built a universal switch box for the … ...

Making time for my next small Arduino project, I need to do something with the rotary encoder direction information decoded by this software. A state machine is what I need, but how to implement it?

This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special mechanical switch to select the operating mode.

Electronic Voting Machine This project is an Electronic Voting Machine (EVM) implemented using Arduino. The system allows users to vote for their chosen leader by pressing a button. The design ensures ...

Smart Switch for Agriculture Irrigation – Circuit and Working The circuit diagram of the smart switch for agricultural irrigation is shown in Fig. 2. As shown, the switch is constructed around a ...

You'll definitely need a few components to build this project, most notably the Arduino control board that'll serve as the brains of the system. This project uses a $30 Arduino Uno R3, an RGB LCD ...
