Solar Tracker

thingiverse

The Solar Tracker: The Solar Tracker aligns itself to the sun with four photo resistors and stays always perpendicular to it. If less brightness is detected in a section, a command is sent to the Arduino Nano, which then controls the servo motors to be perpendicular to the sun again. The solar tracker is made of 3D printed PLA materials and has two SG90 servomotors for alignment. A soldered Arduino Nano on a prototype board serves as the brain of the solar tracker. In addition, it has four photo resistors that act as sensors for alignment. A 2.5W 5V / 500mAh solar panel is used to generate energy. https://www.amazon.com/Longruner-Helicopter-Airplane-Controls-KY66-5/dp/B07236KYVC/ref=sr_1_1_sspa?__mk_en_US=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=sg90+servomotor&qid=1585758227&s=ce-de&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzMjlXSzM4NVQ0VlFaJmVuY3J5cHRlZElkPUEwMzgwMjgwM1RBR1ZEWldJUUNPWiZlbmNyeXB0ZWRBZElkPUEwMTQwNjcxTjdTMVpRMzRRN1dYJndpZGdldE5hbWU9c3BfYXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ== https://www.amazon.com/kwmobile-10x-Helligkeitssensor-Licht-Widerstand/dp/B01LX0ZQHL/ref=sr_1_2?__mk_en_US=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=fotowiderstand&qid=1585758530&s=ce-de&sr=1-2 https://www.amazon.com/Elegoo-Entwicklerboard-Arduino-Atmega328P-CH340/dp/B0713ZRJLC/ref=sr_1_1_sspa?__mk_en_US=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=Arduino+Nano&qid=1585758557&s=ce-de&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEzTlRYNEtSTVhSWEw4JmVuY3J5cHRlZElkPUEwNDU5OTc3MzFBTVg5VTI0VURPSiZlbmNyeXB0ZWRBZElkPUEwODIzNjQ3MjdLMFg3SDVMRFpXVCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU= https://www.amazon.com/AZDelivery-Lochrasterplatte-Lochrasterplatine-Leiterplatte-Arduino/dp/B078HV79XX/ref=sr_1_1?__mk_en_US=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=l%C3%B6tboard&qid=1585758592&s=ce-de&sr=1-1 https://www.amazon.com/gp/product/B073XKPWY7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
