I have two devices. Sensor for temperature and humidity and lcd screen. Both require SDA pin, and I have only one on my arduino.
I want my display to show current temperature but I don't know how to connect two things on one pin.
Can I somehow read from other pins maybe?
Also, what can I do if I have only 1 5V source and I have two devices that require 5V?
My arduino model is Arduino Mega 2560 R3
I have this aosong sensor (AM2301), and I have YwRobots 2 row LCD screen which I want to connect to my board along with sensor.
So... I'm not sure how to connect those two if both require SDA and I have only one.
