Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

This schematic is a project in which we control the switching of bulb/lamp using Arduino and NPN TIP120 Power transistor (used as a switch).

Assembled Device Simplified device circuit The idea A possible solution is to simply introduce a break in the existing circuit and fill in that break with a electrically controlled switch of some sort ...

The ‘unhackable’ switch, which resembles a MIDI sequencer input, runs on an Arduino Nano Every and uses a relay to directly control the power state. Instead of having one keep-alive button ...

C ‘common sense’ is that the switch/case answer is both faster and makes more compact code because compilers tend to convert these into a jump table. However, the Arduino compiler tends to convert ...

Called the Protected Switch Shield, it is also compatible with the firm’s own XMC microcontroller kits which borrow the Arduino form factor. The shield runs from 8-36V and provides a driver circuit ...
