Introduction: Arduino - LCD 1602A KEYPAD LCD SHIELD RELAY CONTROL.

Picture of Arduino - LCD 1602A KEYPAD LCD SHIELD RELAY CONTROL.

Hello world! today i wrote a simple code to control 4 relays with a keypad LCD shield for arduino. You can add any device and the code is easy to modify. I used 1 lamp as a example device. The video displays dutch text on the lcd screen but the code i uploaded is english, "apparaat" means device. Follow the next step for the schematic, Code & Parts list.

Step 1: Schematic, Code & Parts List.

Picture of Schematic, Code & Parts List.

Just wire it up like the schematic, upload the code and it should work.

If things don't work you probably don't have the library LiquidCrystal.h installed.

Parts list.

  1. Arduino mega 2560, I used the RobotDyn Mega 2560
  2. 4 x 1 channel relay KY-019
  3. LCD shield with keypad. <- i bought a bunch of those. shipping fast
  4. Jumper wires set MM/FF/MF
  5. Power cables + lamp sockets.(optional)

Good luck!

Good one... is it possible to use relay code for rotating DC motor clock wise and anticlock wise?
