Solar Panel Charge Controller - 10 A
Charge controller for photovoltaic applications controlled by a microcontroller and capable of operating automatically at both 12 and 24 V.
Overview
It allows to provide the right degree of current to the batteries protecting them from an excess of discharge or charge in order to prolong their life cycle as much as possible.
Attention! use only with 12 and 24 V solar panels.
It protects the battery from polarity reversal, automatically enters protection and locks when the load current exceeds the regulator’s range. In case of short circuit, it enters protection and it overload protection.
To avoid complete battery discharge, the regulator will automatically disconnect the load at a certain voltage that cannot be less than 11.2 V for the 12 V battery and 22.4 V for the 24 V batteries.

It can be tough to get started with building an Internet of Things (IoT) project from the ground-up, as getting connected, serving a webpage, and managing other devices can all be a challenge to a beginner. This is why the YouTuber known as “Mario’s Ideas” made an end-to-end tutorial that details everything one might need to build a smart RGB lamp. Because the Arduino UNO R4 WiFi contains an ESP32-S3 chip for its Wi-Fi radio and Renesas RA4M1 microcontroller, it was the perfect candidate. Mario’s sketch begins with a call to initialize the Wi-Fi module before attempting to connect to his local access point. Once finished, it enters a loop that continuously checks if a client has connected to the web server, and if one has, reads the requested path while also seeing if the string contains “/H” to denote an “ON” command to set the LED. Toggling an LED is useful, but Mario wanted to take things a step further by building a tangible — in this case a lamp. His 3D-printed enclosure features a recessed base and translucent cube for diffusing the light emitted by a grid of NeoPixels. Controlling the color was just as easy since any browser could still send a request path containing a color and get back the lamp’s updated status.
