Another great electronic project from Alan Parekh. In this article, he teaches you how to make a colored lighting for your fish tank. He also give you a hand on how to add a temperature cencored on it. As usual, the how-to tutorial is clear and detail, with images on each step to make you understand better.

Why?
When the tank is cleaned the fish are removed and placed in a small amount of the tank water. The problem is that fish don’t like rapid temperature fluctuations. I guess a simple in tank or stick on thermometer would have done the trick but what is the fun in that? If the unit just did temperature monitoring it would have been such a waste of processor capability, so I thought adding colored lighting would be a great addition.

Overview:

• Uses 16 high power LED’s, 4 red, 4 green, 4 white and 4 blue.
• The tube that the LED’s are mounted in is a section of 3/4 inch PVC conduit.
• LCD Display to display the mode the unit is in and show the temperature.
• Liquid sealed temperature to read the water temperature.
• One button to change between modes.
• Photocell to turn off the lights when there is adequate room light. This is wired and calibrated but this function has been remove to allow the lights to remain on all the time.
