If you doesn't have TTL (Transistor-Transistor Logic) USB and want to do Rx-Tx transmission. Don't worry you can use us arduino. From simple hardware modification you can use your Arduino as USB TTL ...

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. Connect a small bulb between the ...

Below, you will find the circuit diagram of the Arduino DC Motor Speed control using MOSFET Transistor. It is simple and uses a minimal number of components, making it easy to understand. If you are ...

This circuit can be formed by using 4 transistors or MOSFETs, and the motor will be in the center. The overall scheme will look H-shaped, therefore, known as the H-Bridge scheme. We will use signals ...

This repository contains two simple Arduino projects that demonstrate how to control a buzzer using transistors — one using an NPN transistor and the other using a PNP transistor. These are ...
