An example of a larger switch is a transistor.Don’t draw more than 20 milliamps (mA) of current from your Arduino’s GPIO pins, otherwise you may damage it. Such a small current can easily switch on a transistor, and the transistor could in turn switch on a motor, relay (this is ...
Note that in addition to the Arduino, TIP120, light bulb and battery you’ll need a pushbutton switch and a couple of resistors. The 2.2k resistor limits the current into the base of the transistor, while the 10k resistor is a pull-up resistor for the switch. Hook everything up and ...
Once I had a value that worked with my phototransistor, I usedCircuit Canvasto plan out how to connect the everything to a stripboard: The IR LED, phototransistor, two resistors, and nMOS transistor. With that outline, I had a good idea of how to connect everything. But to reduce the ...
The Arduino-controlled relay circuit is shown below. This circuit explains to you how to control a relay with the help of an Arduino. The required components to build this circuit mainly include the Arduino Board, Resistors – 1K & 10K,BC547 transistor, 6V/12V relay, 1N4007 diode & a 12V...

In this application, we will check the DC motor speed using a BJT type transistor. Why do we need a transistor?We know from Arduino's digital pins that the output voltage is 5V. The 9V... ARDUINO LESSON 5: TEMPERATURE MEASUREMENT
See this for example of using mosfet as switch (scroll down below the theory at beginning):https://www.electronics-tutorials.ws/transistor/tran_7.html (replace lamp with fan, rin is optional) If that resistor is much larger then the base resistor it will do little to turn off the transis...
