Description

Description

Create your own computer controller dual axis solar tracker in under an hour, using only a screw driver.

The sun is awesome, and so is solar electric power generation.  Unfortunately for solar panels, the sun moves.  To counter this you can make a tracker that follows the sun and allows for even greater energy production.  This is accomplished by using two micro servos, four sensors, an Arduino Uno, custom laser cut wood, and a whole lot of screws.  By popular request the Dual Axis Solar Tracker was designed to be non-soldering, and all you will need are some screw drivers and a wire stripper.

The Dual Axis Solar Tracker also comes with a very handy solar cell and voltmeter to gather solar data for use in projects and experiments.

How hard is it?  Check out the step by step instructions or video build guide below to judge for yourself!

Contents Include:
• Arduino Uno and USB Cable
• Arduino Sensor Shield
• 2x Metal Gear Servos (9g)
• 1x 5-Port Terminal Block
• 1x 4-Port Terminal Block
• 4x 10K Ohm Resistors
• 4x Light Detecting Resistors
• 4x JST Socket Connector Cables
• Jumper Wires
• 5.5V Solar Cell
• LED Volt Meter

Tools Needed:
• Wire Stripper / Cutter
• Several Small Screw Drivers
• Rubber Feet
• Cable Wrap or Twist Ties (highly recommended)
