This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

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 ...

To the human eye, it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all ...

When you read “Arduino wristwatch”, you fall into the ... A round circuit board holds two surface mount ICs and 12 LEDs. The whole thing looks nice fit snugly inside of a watch body.

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 ...
