This board was originaly made to show my friend who is a software engineer how to reflow electronic componets into a PCB using a skillet.
Originally I prototyped the circuit using : An Adafruit Arduino Board with an Attiny85 MCU (Gemma). Then from Digikey Electronics I ordered some SMD components:
- Attiny85
- 0805 LEDs
- 0805 resistors
- coin battery holder
The Build
Wired 3 LEDs running on an Attiny85 board (Gemma) from Adafruit for power tests. The Arduino sketch can be modified and work with an Arduino Uno (as I have tested).
Used a breakout board to solder the fresh attiny85 to it in order to burn the arduino bootloader to it via ISP Reflowed LEDS, resistors to the PCB along with the attiny85 with the freshly installed Arduino code Added the battery tested connections Finished!
