Arduino Christmas Light Controller

Step 5 Bringing it all together

Once all the plugs are connected and you have every going to where it needs to be, we need to connect each tree to the pcb.

1) i used some wire from the dead lights to connect all the positives on the pcb (image 1)
2) get the crimp connectors and connect some onto the wires coming from the trees like (image 2) leave the white be for now
3) connect those wires to the pcb in the correct order
4) i took an old exstention cord and cut the cord off and connected one end to the 120v input on the pcb and the other to the 2 whites
5) lastly connect the arduino up to the pcb (image 3)
6) tape up those connection and store it somewhere safe
7) upload the Joy To The World code, and see if it works. if so GREAT!!!! if not, not good. if you cant figure out the problem post a comment and ill try my best at helping you.

One thing you have to pay attention to is the 120 volts that comes from your house is a RMS voltage. Never hook up the ground on your AC to an earth ground. Go through your common as this is where your current comes from. Your voltage is on your potential side. I would also make sure the gate is rated high enough so that if there is a spike in your voltage it will send it to the ground thus dropping your voltage to zero.

[grodenbarg]

depends on relay contacts, but yes if it is not rated at 120 on the business end there can be a fire hazard there if overload conditions exist.

BTW: to reduce confusion on wiring the 120 Volt side of this project the "ground" on your circuit plans is actually the "neutral" wire o the house. If it was actually wired to the earth ground, there could potentially be an electrical hazard. :(

 Hopefully it would trip the RCD before then.

[rider2006]

Relay contacts are rated at 30VDC, are they being used at 110 V?

[Minifig666]

 Because he is referring to the American AC mains. You can have a higher voltage at AC.
