Hi, I got a Grove Loudness Sensor (http://wiki.seeed.cc/Grove-Loudness_Sensor/) with the Brickpi3 on Raspberry Pi3. However, it doesn’t get any response when I ran the example program from their wiki, and further I scanned I2C devices by “sudo i2cdetect -y 1”, and nothing was showing on the bus.
The Grove Loudness Sensor is an analog sensor, and does not work on an I2C Grove port. There is no direct way to use it with the BrickPi3. You can use it with GrovePi or GoPiGo3, or if you’re handy with a soldering iron and hacking, you could probably adapt it to be used on one of the BrickPi3 sensor ports.
