# 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
|
||
|
||
```
