Introduction: Since the LD2402 infrared uses a baud rate of 115200, while the IR05 module is set to a default baud rate of 9600, both use the same GPIO pins 4/5 on the ESP32C6. After checking the specifications of both products, it turns out that the IR05 supports 115200, so I changed the baud rate … Read more
Obstacle Avoidance Car Based on 51 Microcontroller PART 010151 Minimal System Board For the 51 microcontroller, simply add a crystal oscillator between XTAL1 and XTAL2, and connect a capacitor to ground on each side of the crystal. The microcontroller has an inverter inside, and with the capacitor and crystal, it can oscillate. Reset is done … Read more
When learning about microcontrollers, we often deal with various modules.Today, we will master the analysis of four sensor modules, which are the infrared obstacle avoidance module, sound control module, and human infrared module.1. Infrared Obstacle AvoidanceModule OverviewThe infrared obstacle avoidance module has a pair of infrared emitting and receiving tubes. The emitting tube emits infrared … Read more
