This is 8 digital bits serial LED display. It features a flick free display and 3-Wire interface which allows more than 2 modules can be serial linked. With our interface shield, this module can be plug and play.
This is an arduino rotation potentiometer , it is able to rotate upto 300-degree. With the Arduino IO expansion board, in combination, it can be very easy to achieve position-dependent interaction with the rotating effect or produce MIDI instrument. So with this sensor you can learn how rotary potentiometer works and what analog signal is. You can have much fun with this basic input device.
Gravity Interface is adapted to allow plug&play. The IO Sensor Expansion Shield is the best match for this sound senor connecting to your Arduino. As this sensor can work at 3.3V which make it compatible with Raspberry Pi, intel edison, joule and curie.
