Read and flash RW1990 keys using arduino.
RW1990 aka RW-1990. Most likely RW-1990.1, ТМ-08, ТМ-08v2 will be working.
It should be something about 'PCB'
You will need:
- Resistor 2.2k
- Arduino Nano. Or not Nano, Uno is also good. Or you can pick some Arduino-compatible board.
- Wires x3
Long story short: pull PIN 10 over capacitor to VCC. Plug this pin to the center of the iButton key. Key 'borders' should be connected to the ground.
Just take a look on what_is_it_should_be_look_like.jpg
To read key just flash snipped as is.
To write key you need do next steps:
key_to_writeto key you want to write.
- Find in code '// UNCOMMENT THIS SECTION FOR FLASHING KEY' section and uncomment this section.
- Flash. Check. Get satisfied.
