  • Interface I2C 16x2 LCD with Arduino Uno (Just 4 wires) 8 months ago

    Its because you are using some other library for I2C Display. Follow the steps and please don't skip step 3, The library mentioned there. And importantly , to avoid conflict , please remove old library for i2C and then add "Arduino-LiquidCrystal-I2C-library-master" That mentioned step 3 .

  • Interface I2C 16x2 LCD with Arduino Uno (Just 4 wires) 8 months ago

    There is no error in the code. And also "lcd.begin" function exist. Make sure you are using the exact library that i have mentioned here (Arduino-LiquidCrystal-I2C-library-master) . Refer "Step 3"

  • Interfacing Bluetooth Module (HC-05) with Arduino Uno about 1 year ago

    The working voltage of HC-05 is 3.3V. Actually that is two boards. HC-05 is attached to the base board. There is a voltage regulator in that baseboard. So we can use 5V in that base board. It'll regulate it to 3.3V and power up HC-05.
