Quick LED heart project for Valentines day

If you are engineer in love than you should take an advantage and build something beautiful for Valentines day. So why not go with flashing heart. Mike suggests building simple PIC12F629 based heart powered by single CR2032 battery. He designed through hole PCB so anyone could easily build and assemble. The shape has 12 – 3mm red LEDs placed around. With single button it can be turned on and different flashing modes selected. He shares all building plans and asm code in case you would lake to tweak something. So don’t hesitate and build one as small things can mean a lot to someone. Continue reading

Say “I Love You” with Arduino

Take a look at this Arduino controlled Charlieplexed LED heart project might be this will be exactly what you need to do. It looks pretty simple, but there is some science in it. It uses 27 individually addressable LEDs and uses only 6 wires to control them. This is so called Charlieplexing wiring. When board is ready this is up to your imagination what to display. You can try out ready made software for this that is located here, or you can write your own and you don’t need to be tied to Arduino. Heart can be attached to… Continue reading
