I am trying to connect an ultrasonic sensor SFR08 and two SHARPs using the analog input port of the Arduino UNO. The SFR08 is connected to A4(SDA) and A5 (SCL) and the SHARPs in A0 and A1. The issue is that the ultrasonic sensor and the SHARPs only work by separated, this is the SFR08 works if the SHARPS are disconnected and the SHARPs work if the ultrasonic sensor is disconnected.
The question is: Is it possible to use the inputs A0, A1, A2 and A3 when I using the I2C protocol on A4 and A5 and the wire library? ¿How should I connect these sensor for them to work all together?
Thanks for your help.
