Using Hall sensors
A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field density. Hall sensors are used for proximity switching, positioning, speed detection and current sensing applications.
We have designaded an interface to control an emi through hall sensors.
Schematic:
You can see below a hall sensor picture. It usually has 3 pins, two dedicated to power supply and the third for the output. When you put a magnet close to the hall sensor you will get a variation in output voltage.
You have to plugged the sensor in the "SENSOR-IN" pin headers. At "OUT-IN" pin headers you have the output voltage but also you have to connect your external 5 volts and ground.
Connect the output to the control pin of some emis and you will have a magnetic controlled experimental music instrument.
