The DS18B20 temperature sensor is a one-wire digital temperature sensor. This means that it just requires one data line (and GND) to communicate with your ESP8266 board. Each DS18B20 temperature sensor has a unique 64-bit serial code. This allows you to wire multiple sensors to the same dat...
Another illustration that demonstrate how to wire the i2c 16×2 LCD on ESP8266 12 Known as NodeMCU, as you can see the diagram below the SCL as Arduino Analog Pin A4 is connected to D1 on NodeMCU at the same Wiring ESP8266 nodeMCU with HCSR04 Ultrasonic Sensor ...

Get functions using EEPROM PUT and EEPROM, you can read and write the EEPROM shown in the program below. In the following example, we will write int and string data to EEPROM and read them through serial input from the user. ESP8266 EEPROM CODE Using theEEPROM putandEEPROM getfunctions, yo...
Garage door monitoring system The project utilizes three main hardware components: ESP8266, PIR sensor, and a motor. The system is designed to automatically open the door in response to detected motion using the PIR sensor. Additionally, control over the door is facilitated through the Blynk dash...
