Woohoo, almost there
Many thanks once again MrDEB, your answers have provided me with a greater understanding of how this circuit works. I'm also a bit excited about heading to Jaycar to buy the parts now
If you've the patience to humour me I've a few more questions just to make sure I'm on the right path before I attempt making this circuit - as there are a few things I've not quite got my head around:
1. Does the rating for the wallwart that connects to the sensor depend on the PIR sensor rating alone? Based on the one I linked earlier I assume it's 5v max, but what current should the wallwart produce?
2. Are these 2 points where the wallwart connect? And does it matter whether the positive goes to one or the other?
3. Are these ground connections? Or part of the D.C. power? - again, sorry for the really naive question.
4. Is this roughly how the light would be connected to the triac?
5. Jaycar don't seem to have the MOC3041, would the MOC3020 or MOC3021 suffice instead?
I've made lamps running off 240v before but have never attempted to go down the electronics route before, rather than the simple in-line switch... I'm really enjoying learning this and will be sure to have the fellas at Jaycar help me out to ensure I'm safe
Thanks again!
