Hi Guys,
Just joined and would like to ask a question about feasibility. I have been in engineering all my working life and need to pick your expert brains to see if what I am proposing can be done with an Arduino. I have built a waste oil swimming pool heater that works pretty well manually but now I have to automate the controls. I need to control 240v ac pumps, a pre-heater circuit, an igniter, some solenoid valves and also monitor temperatures and flame detection. There are various fail-safe sensors to consider also such as flow switches and pump after-running in the event of flame out. Ideally I would like the system to attempt to relight 3 times after which it all shuts down and needs a reset after investigating/rectifying the lack of igniting. It all seems to be a question of logic control with multiple inputs and outputs and relays in series and parallel. I know this is just a brief summary of what is required with no flow diagrams etc but just wondering if this sort of project could be handled with either an Arduinio Uno or Due/Raspberry Pi before I attempt to butcher an existing waste oil heater and pull all the guts out to incorporate in my set-up. Any help or advice gratefully appreciated. If you need more info about what needs to happen and sequencing I can let you know as I have been working on the specifics for some time.
