In this post I am going to talk about the “solar Tracker” which I’ve made using a Arduino UNO and SG90 servo. Before reading the post please check the video from my channel , it gives 70% of Idea about the project. So I’ve made a solar tracker using an arduino and servo motor. This solar tracker uses two LDRs to measure the light or the resistance of the LDR changes according to the light. It can also charge mobile phone.”
