“Winter is here, and the most interesting thing in winter is Christmas. As a PCB designer, I decided to build something useful for Christmas and so I made a blinking PCB snowflake for Christmas tree decoration. we can use this to decorate our Christmas trees, walls etc. The flashing of LEDs will attract everyone. So let’s see how I made this.
following are the things required in this built-
- 1555 timer IC_
- Custom PCB
_- 110K Resistor -0805
- 31kiloOhms Resistors-0805_
_- 110uf Capacitor-0805
- 110nf Capacitor-0805_
_- 12LEDs - 0805
- 6LEDs -1206_
_- 1SOT-23 2n2222 transistor”
