# arduino_rw1990
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](what_is_it_should_be_look_like.jpg)
### HOWTO
To ***read key*** just flash snipped as is.
To ***write key*** you need do next steps:
1. Set `key_to_write` to key you want to write.
2. Find in code '// UNCOMMENT THIS SECTION FOR FLASHING KEY' section and uncomment this section.
3. Flash. Check. Get satisfied.
### Example
Read:
```
.........
[1:F0:88:12:1:0:0:2E]
[1:F0:88:12:1:0:0:2E]
[1:F0:88:12:1:0:0:2E]
[1:F0:88:12:1:0:0:2E]
..................................
```
Write:
```
..
[1:F0:88:12:1:0:0:2E]
++++++++
[1:5F:69:B:1:0:0:EA]
[1:5F:69:B:1:0:0:EA]
programmed to KEY requested
[1:5F:69:B:1:0:0:EA]
programmed to KEY requested.....
```
