A year ago I create a project for an Instructables contest using an Arduino. I came up with the POW-Rduino. I would use it to test my prototypes and arduino sketches. At the time I based my design on the work done by Luke Iseman’s “The Garduino – Garden Controller”. He build a relay to control the water pump in his system. I wanted to duplicate his project so I could learn how to use relays and develop sketches for the arduino for my projects. So my first project was the POW-Rduino:
The performance of the unit was not good. So I moved the POW-Rduino to the do later projects box.
First of the year (2010) I found what looked like a relay that would be able to replace the weakest part of my unit.
I had a hard time understanding how the thing worked. So I wrote an instructable about it:
What I learned on this project was very helpful and allowed me to re-construct the POW-Rduino with the new relay brick and the unit performs each and every time on a consistent basis.
Here is thedifference in the relays:
Next came the re-design of the front panel. The new relay had a signal connection for each relay. So I had to make room for this item in the design on the front panel.
