When you read “Arduino wristwatch”, you fall ... is much more polished than that. A round circuit board holds two surface mount ICs and 12 LEDs. The whole thing looks nice fit snugly inside ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Did you know that you can use Arduino to turn on an LED when you press a button? Well, it is true, you can do this! Leaving the joke aside, let me show how you can achieve this. You will need the ...

so I built her a "Button Box" based ... Not-well-secured LEDs - not excellent. A bunch of hot glue fixes this. The LCD is secured similarly. I generally power my Arduino projects from a shield.

[Alex] needed a project for his microcomputer circuits class ... it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it ...
