*Circuit Explanation, This setup includes: Arduino UNO Breadboard, Wires connecting everything together, 3 push buttons,3 LEDs (with current-limiting resistors) LEDs Description: LEDs placed on the ...

Each LED is connected to one of the Arduino's digital output pins through a 220Ω resistor. A push button is connected to each input pin and uses the internal pull-up resistor feature of the Arduino.

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
