Re: raspberry pi3 connect -relay- Solenoid

I have seen that some people connect directly to gpio because some gpio pins are internally connected with resistor. Google about pull up and pull down resistor.

Re: Running a windows program off a Raspberry pi?

I don't think so jadro. Mono runs programs built using .net bytecode. C# for example. Which happen to be .exec files. That is not the same as running good old x86 binary Windows executables. See this topic about mono. I do not know about mono but this is topic: https://www.raspberrypi.org/forums/vi...

Re: ir receiver problem

Joan,
I have looked on ir_hasher.py and I see array called hashes.
Do I need to put my AIR Condition remote buttons received codes here? As I see, this is just for receiving signal from remote, not a transmitter? But I see it is recorder and playback or transmitt, no?
