Hello all, Currently I’m going to adapt my Arduino 9 Shield Board for securing my CNC Maschines against unallowed access. Code has been used together with an older Arduino Nano Shield. Following fuctions are implemented:
- set master iButton with first use
- delete all allowed iButtons except master
- add new iButtons
- 1-Wire Temperatur
- show hours since switch on
- list all Hex-ID’s of allowed iButtons during startup
- show status with IButton Reader (green (ON) or red led(OFF))
- switch relais on/off if valid iButton as been touched on iButton Reader
- emergency Button push controll (switch off releais)
- display DS1307 (RTC) time
- correct time with spare Arduino Nano V3 durring upload –> new time will be programming time
