### If using the makefile (Linux/Mac)
|
||||
- Make sure you have installed [avr-gcc toolchain and avrdude](http://maxembedded.com/2015/06/setting-up-avr-gcc-toolchain-on-linux-and-mac-os-x/).
|
||||
- Connect your programmer to your PC and to the ATtiny.
|
||||
- Open the makefile and change the chip if you are not using ATtiny85 and the programmer if you are not using usbasp.
|
||||
- Open a terminal.
|
||||
- Navigate to the folder with the makefile and the Arduino sketch.
|
||||
- Run "make install" to compile, burn the fuses and upload the firmware.
|
||||
- Run `DEVICE=attiny85 PROGRMR=usbasp make install` to compile, burn the fuses and upload the firmware (change DEVICE and PROGRMR accordingly).

# Operating Instructions
|
||||
1. Connect the device between a power supply and a consumer.
