Circuit Documentation

Summary of the Circuit

This circuit is designed to interface various components with a MakerEdu Creator microcontroller board. The circuit includes two MKE-S11 IR Infrared Obstacle Avoidance Sensors for detecting obstacles, an MKE-M02 Push Button Tact Switch Module for user input, an MKE-M15 Bluetooth module for wireless communication, and an MKE-M08 LCD2004 I2C Module for display purposes. The circuit is powered by a 5V supply from the MakerEdu Creator board, which also provides ground connections to all components. Communication between the microcontroller and the Bluetooth module is achieved through serial communication (RX/TX), while the LCD module communicates via the I2C protocol (SCL/SDA). The obstacle sensors and push button are connected to digital input pins on the microcontroller.
