Can I use The mpu6050 with this? I am making a project with 3 arduinos (2 slave, 1 master) and I want to know can I use the mpu6050 since it uses the I2c communication.
You can but keep the I2C wires less then about 30cm. If they are going to be further apart consider something like RS485 or CAN. Are you sure you need three?
