Of course, below I will provide a complete example of Arduino serial communication. This example will demonstrate how to perform simple data exchange between Arduino and a computer. We will write a program that receives characters from the computer and performs different actions based on the received characters. At the same time, Arduino will also … Read more
1. Hardware Preparation You’ll need an Arduino development board (such as Arduino Uno) and several LED lights. Connect the anode (long leg) of the LED lights through a current-limiting resistor (usually a few hundred ohms, such as 220Ω, to prevent excessive current from damaging the LEDs) to the digital pins of the Arduino board (for … Read more
