Join Zahraa Khalil for an in-depth discussion in this video Combine them all: LCD + keypad + LED, part of Learning Arduino: Interfacing with Hardware.
- [Instructor] All right, so we've went through the three…components, so now we are going to include…the seven-segment LED with the LCD and the keypad.…So, we are going to keep the same…wiring for the seven-segment LED,…the same wiring for the LCD,…and the same wiring for the keypad.…The only difference, however,…is that so the shift clock,…which is in pin eleven, the shift register,…is going to be connected in pin nine…in the Arduino board over here.…And it was previously connected to pin eleven,…but I used pin eleven to connect it to the LCD.…
So, if you are going to use two bread boards,…exactly what I'm doing,…so you need to keep the connection between…the two bread boards,…so the positive to the positive,…and then key brand common.…So now, the last piece is connecting…the five volt…here and then ground to ground.…
All right, so now we have the three components together…connected to the Arduino board.…All right, so to start the coding,…why don't you go ahead and open the file 0410 Keypad…7 segment LED LCD start project.…
