This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

I made a small LED 💡 project in which there are 10 LED whose blinking speed varies using potentiometer(with the help of ARDUINO uno) the real world example of this ...

This Arduino project uses a potentiometer to control the state of 8 LEDs. As the resistance of the potentiometer is adjusted, the analog signal is read and mapped to a range between 0 and 8, which ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

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 ...

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...
