My electronics knowledge is extremely basic, but i have started playing around with Arduino Uno to which i send commands from a C# program. For a next project, i would like to extend my set up in order to use my computer to control a smoke machine similar to the one bellow:
It is a 400W fogger, powered by 220~250V at 50-60Hz. You basically turn it on, and then use the (plugged-in) remote in order to blow smoke (or not). Ideally, i would like to replace the physical switch on the remote and use an Arduino to communicate with the fogger and trigger the smoke blow. I found similar posts (e.g. Replacing a mechnical switch with a digital one), but they seem rather complicated compared to the set up i have at hand. I opened the remote and here is a Fritzing sketchup of its inside:
I saw some posts mentioning the use of relays in order to control the remote state (BLOW or NO BLOW), and i do have a small relay at hand that was shipped together with my arduino kit (1 Channel 5V Relay Module). To my understanding, you have to be careful when using relays since without proper knowledge you can damage your hardware or even harm yourself pretty badly.
I guess i am looking for a few tips or hints from other people (since i am quite a beginner and have nobody around me i can ask for advice) on whether or not using a relay would indeed be a good option. Any other comment or information is of course more than welcomed.
Thanks in advance
