Arduino Definitions
#define IR 0 #define BTN 1 #define GND_detect 3 #define LED 4
Programming Setup TX/RX to pin PA1 and PA2
- Arduino pin reference please see here: https://github.com/SpenceKonde/megaTinyCore/blob/master/megaavr/extras/ATtiny_x02.md
Programming
- Prepare Arduino Nano UPDI programmer
- Connect UPDI, VCC and GND three lines
- upload code by "uploading using programmer", and select programmer "jtag2updi"
Power supply
- Power supply can be attached from B+ | B-, or SO+ | SO-, if you use solar panel better applied at SO+|SO-
- Power supply up to 30V DC
- For lower than 5V, you can shot connect the pads next to the LDO, to supply power directly to LEDs
