Arduino Uno To Control External LED This project demonstrates how to connect and control an external LED using an Arduino Uno. It’s a simple and fundamental project that introduces the basics of ...

The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND. #include ...

Instructions Connect the components as per the circuit connections mentioned above. Upload the provided Arduino sketch to the Arduino Uno using the Arduino IDE. Once uploaded, the LED connected to pin ...

On the right hand side there a voltage regulator with smoothing caps. The left side hosts the obligatory pin 13 LED, and the crystal oscillator can be glimpsed on the far side of the ATmega328.

Components Required As we are going to do some basic I/O practice, the components are going to be more straightforward. Arduino UNO R3 Board x1 LED 5mm x1 Push Button x1 10K Potentiometer x1 SG90 ...

Gas leaks can pose serious safety risks, especially in homes, kitchens, and small commercial spaces. In this project, you'll learn how to build a simple and budget-friendly gas leakage detector using ...
