Solar tracking using Logic Chips

Two-chip single-axis tracking

This is the most basic solar tracking available, and is all you need on the Moon. It even works reasonably well on Mars.

What you need:

• Kit (Logic I/O) x2
• Kit (Sensor) > Daylight Sensor

Place the Daylight Sensor on a vertical surface (e.g a wall) facing sunrise or sunset (doesn't matter which), with the Data Port facing north.

Logic Reader	Daylight Sensor	Vertical/Solar Angle
Batch Writer	Logic Reader	Vertical	Solar Panel

Hand-crank the panels to face the sunrise, and they will do their thing.

Six-chip dual-axis tracking

To get a "100%" accurate solar tracker on planets with an offset solar arc, you need to include the Horizontal component to the solar angle.

What you need:

• Kit (Logic I/O) x4
• Kit (Logic Processor)
• Kit (Logic Memory)
• Kit (Sensor) > Daylight Sensor

Place the Daylight Sensor facing up, with the Data Port facing north.

The panels should align themselves to the sun if you make sure to put the Power Port on the panels facing east (90 degrees).

Solar tracking using Integrated Circuits

This is the most powerful way to track the sun, but the implementation might be a bit daunting at first.

What you need:

• Integrated Circuit (IC10)
• Kit (IC Housing)
• Kit (Sensor) > Daylight Sensor

And if you don't already have one set up:

• Kit (Computer)
• IC Editor Motherboard

Place the Daylight Sensor facing up, note which direction the Data Port is facing, and which direction the solar panel Power Port is facing. These two directions are needed in the code. The Daylight Sensor is connected to the d0 screw, that's all you need.
