Ok, so I bought a cheap 500watt smoke machine. It has a 5 pin controller which actually only uses 3 of the pins for the switch and the 'ready' lights. What I want to do is replace the switch with the netduino to time how often the smoke machine outputs. Now I have looked online and seen a few people using arduino's and the like but I think I need help on what to use. First of all I checked the voltage across the switch. It seems it reaches a max of 108volts and the current reaches about 40-50mA. I'm guessing this is powering the pump directly to pump the smoke fluid into the element. So, i'm stuck as to what to use? Can I do this with a transistor? or do I need a relay? Also what type of transistors/relays? I'm quite new to electronics and get confused easily Thanks Rexz ** Just realised this may have been posted in the wrong area. Please could a moderator move, thanks.

Ok so I have an idea but I don't know if its actually possible. What I would like to do is have the arduino stream sound from a computers soundcard over the network. I would also like the netduino to in turn, stream a microphone input back to this computer. The idea I have is that the netduino will be like a client which will have the speakers and microphone. The computer or server itself will handle the voice communications. Would the netduino be able to handle this? I understand it would take some coding to get this all working, but I'm not sure on the capabilities of the netduino. Obviously all this will be created on a Netduino Plus. Any ideas would be great. Thanks
