Homemade Heart Shape Led Decoration Light using Arduino
Welcome Friends, today I’m going to show you how you can make an Arduino based heart shape led decoration light. I have used 2 pcs ULN 2003 and 1 Atmega3218p ic. but you can use BC547 transistor instead of ULN2003 IC. If you use BC547 transistor instead of ULN2003 IC, then the circuit diagram will be a little… Read More »
