I have an Arduino Mega 2560 that I need to connect 4 MPU 6050/Gy 521's to.
I found some resources on the Mega and Uno, however I'm having trouble piecing them together.
This resource gives great detail for connecting a single MPU to a mega. http://dummyscodes.blogspot.com/2014/07/mpu6050-gy-521-breakout-arduino-mega.html
This resource gives a trick for connecting multiple to an UNO. https://playground.arduino.cc/Main/MPU-6050
My problem is that the wiring for the Uno and Mega are different. The resource I have for the UNO describes using the MPU AD0 (output) connecting it to different output pins for each MPU. The resource talking about the MEGA doesn't even use the AD0, and uses INT but I'm not sure if I can use the same concept.
Plus, I still don't actually understand how to connect/what other pins to use for the other 4.
I'm pretty new to Arduino, definitely new to anything with wiring.
Please help! I'm really confused about using multiple together, and about how to properly wire them.
