I need some help. I have relay board (this one: http://www.emartee.com/product/41391/Arduino%205V%20Relay%20Omron%20G5LA). When I first got it I hooked it up to a simple lamp and the Arduino to test it out and it worked great.
I am currently working on a sous vide cooker project using this. I have hooked it up along with an LCD, a pot, and a sensor and now it is not working. It has power and the little LED on the relay board is going on and off but the relay is not connecting the power to the lamp. To trouble shoot, I set up a simple sketch again with just the relay turning the lamp on and off again and no go.
A strange thing is that sometimes when I hit the reset button on the Arduino and it reboots, the relay with flash the lamp on and off for a split second.
