Arduino Interfacing with LDR sensor diagram and its working Following figure depicts arduino uno board interfacing with LDR at its 5V, GND and A0 pins. One can use other boards such as ESP32 or ESP8266 or any microcontroller boards for interfacing LDR sensor with analog read input. Arduino LDR...
Interfacing LCD module to arduinois another important step in this project. JHD162A is the LCDmodule used here. JHD162A is a 16×2 LCD module based on the HD44780 driver from Hitachi. The JHD162A has 16 pins and can be operated in 4-bit mode or 8-bit mode. Here we are using the...
Development of a Line following robot, which responds to light and sound, interfacing microphone, DC motors, LDR's, LED's, speaker with Arduino. Using MOSFET and BJT to amplify to drive the motors, and using LM358 as an audio amplifier. ...
