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