alright so my new project is to control 10 relays (8 valves momentary & 2 compressors on/off) with the arduino via a C based app. I am new to mac about 2weeks and i have never wrote C to interact with a gui so im battling that demon now. I would like to implement this into an objective-c app later, can i code it simply objective-c?
Within my searching i have found the way to physically connect the relay and i think im good there
However I am having a hell of a time understanding the todbot write up posted in the playground, i can honestly say my contacts fell out twice due to lack of moisture...
Basically all I have gotten from the arduino-serial app is that the serial must be initialized before data can be sent/received but how that actually works isn't exactly self explanatory
