The TIP120 acts as a power broker or gatekeeper between the Arduino realm and the high power realm composed of the PC fan and its battery pack. It can be used with an Arduino to drive motors, turn lights on, and drive other high power gadgets.

THE TIP120 DARLINGTON TRANSISTOR The TIP120 is an NPN Power Darlington Transistor. ![]() } Download: Tip120 code Thank you for visiting. Figure 14-5 : Our small electric motor The TIP120 Darlington Transistor A Darlington transistor is nothing more than two transistors connected together. How to control the speed of a DC motor using the TIP120. Int Motor = 2 // the number of the Motor pinĭigitalWrite ( Motor, HIGH ) // turn the Motor onĭigitalWrite ( Motor, LOW ) // turn the Motor Transistors like the TIP120 are really great for controlling high-power devices from your microcontroller, but they do have some limitations. How a Darlington transistor can be used to drive motors, relays, and solenoids with the Arduino. The 1n4004 Diod protect from reverse voltage and it’s a good idea to use it in our circuits. That is why we use the Tip120 transistor. 10mA Base current is plenty enough to fully switch the TIP120. This provides very high current gain, but doubles the required Base bias voltage and increases the Collector saturation voltage. Arduino tip120 Motor: The current provided by Arduino nano digital pin is not sufficient to run a motor, The TIP120 is a Darlington transistor pair, which consists of two transistors with the Emitter of the first one connected to the Base of the second one. ![]()
