Topic: Command two LCD displays with only One Arduino  (Read 617 times) previous topic - next topic


Is it possible to command two LCD displays with one Arduino Mega?
If it is possible, HOW CAN I DO IT ?

It can also be done with i2c based LCDs.
You can talk to multiple LCDs on a single i2c bus using only the two i2c pins.
This is one of the big advantages of using i2c; adding more devices does not require using any more pins.
