I use a microcontroller to control various processes in my home brewery that is essentially a black box. It does it's thing very well, but I can't change it's firmware.
It has multiple thermistor inputs, multiple 5V control inputs, and multiple 5V control outputs. I'd like to design a breakout box to relocate some of the I/O to a remote location, about 50' away. I have played with arduinos, and I'm a competent programmer, but my electrical knowledge is lacking. I'm curious is anyone has input, or if this is even possible.
- Existing "black box" controller sees I/O just like it does now
- 2 or more JeeNodes act as wireless bridges between the controller I/O and endpoint boxes
My main concern with this is the thermistor inputs for the controller. Is it possible to create a circuit that looks just like a thermistor to the controller box, but is actually being read elsewhere?
