Probably you saw Sun tracking system before; however do you have the urge to challenge yourself to make a Sun Tracking Unit?
First of all, get a tiny .7″x1.4″ PC board using the LED3X sensor concept. This circuit uses power MOFSET drivers, which most any DC motor can be used without any modification.
You might noticed that the power drivers are good enough of delivering about 50 amps of peak current or even more. The current will increase accordingly to the transistor. This mean the large power MOFSET, 72A when operated in low current, it will eliminates the needed for a heat sink on the transistor. Cool, isn’t it?
The duty cycle can easily adjustable from 0% to almost 100%. The function of duty cycle is to slow down the motor drive speed.
The LED Remote Sensor
1. The Single axis
2. The Dual axis
Besides that, it also exists in “parking” or “no-parking” on axes as well.
Hope you all will enjoy this fun DIY project. [Source]
