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).

Presenting Arduino Ambient Lighting System. Enable a backlight LED ambient system on your monitor/TV controlled via computer or iPhone. You’ll be able to switch lights on/off, control light power or ...

Microcontrollers—such as the ATmega328P chip that powers the venerable Arduino Uno as well as the Nano—allow you to take input from sensors, power LEDs, and send signals to other devices over ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

A switch is the most essential part of any circuit. Different circuits use different switches in them. In this project, we are going to use a Touch Dimmer Switch. This switch is a touch-sensitive ...

The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

Ever since the development of the first working transistors in 1947, the electronics industry has experienced tremendous growth in numerous ways. For instance, transistors allowed for the ...
