I have a feeling this is going to be another silly question for the ez-gurus to snigger to them selves at, but i'd like to know if there is a device that can be used as a switch. In my case to turn a light on and off using the EZ-B. I played with the idea of using a servo as a switch but I am not really convinced this is the best way to go.
I would rather go with the MOSFET circuit because there is less of a voltage drop between the collector and emitter which is more heat dissapation and slightly less power to the load. TIPs work fine but if I had a choice I'd go MOSFET.
Here is Rich's tutorial on TIP and MOSFET circuit building.
I can't believe the TIP/Mosfet wasn't mentioned until post #9. Obviously, depending on the load, the TIP may be perfect, if not then it can be adapted to switch a relay if you can't find/don't want to use a pre-made board.
@jaychadw - You'll get used to this forum being totally different to pretty much all others in that everyone will help and nobody has an attitude or makes you feel stupid. Ask and you'll find someone will answer pretty much anything without judgement
Sorry Rich, I was going along the pre-made options first.
I realize I am late in this conversation but I will chime in. I used tip Darlington switching transistors to trigger standard automotive relays. I did this because I wanted to know what the components were capable of and I could use adequate equipment. On my fishtank controller I currently have 5 tips wired to trip relays that feed 110v household power to things like lights , pumps ect. I could have used premade ones and spent more money but most the premade units are not intended for AC 110v use. So I'm happy with what I have and wouldn't have done it differently the second time. I would only suggest a smaller case than I used
wow guys, that's a lot of info. You guys are awsome
@Rich i'm getting there. Although I think i'm left permanantly scarred from some of the forums I've been on. You can wait days for a response only to be treated like an ass.
I haven't made a definite decision about which way i'm going to go with this, i'll be checking out that tutorial ( thanks @Troy and @Rich ) and look into those others like TIP/Mosfet
@Jaychad , awesome! Looks like your question is definitely answered. Could you mark the thread answered and give one of the members credit for helping out ?
Thanks in advance! - Josh
thanks guys
