ESP32 Zodiac Clock

This project is ideal for students who are starting with microcontrollers and especially with ESP32s. The idea of this project is to provide a fun way to learn how to control addressable RGB LEDs so that the student does not get bored and finds learning fun.

This project has as its main core the ESP32 C3 microcontroller, which is perfect for this type of project that does not require a lot of power or many GPIOs. The circuit is powered by an external 5-volt power supply and a USB port.

The addressable LEDs in the circuit are WS2812B, which with a single GPIO can control hundreds of these LEDS. The different sequences of the LEDs can be controlled through the 4 buttons on the PCB on the back. There is also a simple LED that can be controlled for different uses.

There is also the option for the student to control the LEDs via WIFI or Bluetooth thanks to the fact that the ESP32 C3 comes with these integrated technologies. There is a 6-pin header which is connected to 6 GPIOs of the ESP32 C3 for general use in other applications.
