Pump + is powered from 3.3V pin of the Arduino. Pump − is controlled via the 2n2222 transistor, which is connected to Arduino pin 13,12,8,7,4. Arduino Pin 2 controls the transistor's base to switch ...

Now ChatGPT works Well, we are ready to ask ChatGPT to begin producing the project in question. As mentioned earlier, the project will consist of the following components: an Arduino Uno board (or any ...

Connect the 2N2222 transistor to the pin3 of the Arduino with a resistor connected to the base of the transistor and collector terminal to the 5V of Arduino Uno.

Right indicator pin (Arduino pin 3) will control the right indicator light in the same way. Transistor (e.g., 2N2222) Connection: The Arduino pin (2 for left, 3 for right) connects to the base of the ...
