About. 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).

When reed switch is opened, pin 2 of Arduino goes high with the help of the pull-up resistor R2, and the alert signal is available through the piezo-speaker PZ1 (not an active piezo-buzzer). At the ...

I have a usb 2.0 powered external device (A mouse jiggler) that has a simple touch interface based on-off switch. The one that I am using in this project can be purchased off of Amazon here. The ...

Spread the loveSchematic drawing software for Arduino, Raspberry Pi, and other Single Board Computers (SBCs) is essential to developing electronics projects. When it comes to creating circuits on a ...

To solve the problem without sourcing a new switch, [Jean-Noel] built his own Arduino based Dahlander switch. This consists of three relays that select the wiring configuration for each speed mode.

Electronic, Arduino enthusiasts and makers looking for a project to keep them busy this weekend, may be interested in a cool custom switch created by Dave. Skip to main content; ...

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 ...

Infineon has developed an Arduino shield to demonstrate the potential of its 24V Profet protected power switches. Called the Protected Switch Shield, it is also compatible with the firm’s own XMC ...
