AC LED Dimmer Module

Projects Programming
1

Good evening all,

I am new to this Arduino coding but I must say I am enjoying the challenge thus far.

I have assembled a street lighting project whereby the 120 Vac photocell outputs power when engaged, to a transformer/rectifier module:

This powers the Arduino UNO R3 and the dimmer module:

The output from the dimmer module powers the LED bulb.

The problem is I cannot get the LED to dim. I have tried codes from others found online and in the Examples folder but to no avail.

The LED needs to dim to about 30% brightness for about 10 seconds then back to 100%.
I am using Pin 3 as SYNC and Pin 10 as GATE for the dimmer module.

I will be very grateful if you can advise a sure way forward at earliest.

Thank you very much.

Hi,
Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.
http://forum.arduino.cc/index.php/topic,148850.0.html then look down to item #7 about how to post your code.
It will be formatted in a scrolling window that makes it easier to read.

We need to see your code.

Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?

We need to see how you have connected your project.

Thanks.. Tom.. :slight_smile:
