This includes light and heat sensors, switches (when wired as in diagram), PIR sensors, electrical signals from fish, or plants .. You can also connect almost any of the iCube sensors from Infusion systems or phidgets .... BUT make sure you have the right polarity.

+V pin ------------ connect the sensor, switch between the +V and the middle sensor pin

middle sensor----- connect a load resistor (typically 1K ) between the sensor pin and the 0v

0V pin ------------

Making a sensor cable, wiring the end with a resistor, a mounted Light Sensor

The ADC ports are set to give you a range from 0 (for 0 volts) to 255 (5 volts). But you can set an upper and lower limit on this range and so focus the range to a smaller more sensitive area (see Sound Lathe project). Future releases of the muio software will allow you to compare between inputs in various ways.

What sensors can I attach?

• Light Dependant Resistors
• Switches (tilt switches, reed switches, button switches, two touching bits of metal
• switches)
• Passive Infra-red detectors (from burglar alarms)
• Thermistors (heat)
• potentiometers (10k linear)
  

a poteniometer wired for use as a sensor or to set sensitivity (see below)

1. a 10K potentiometer
2. 3 pieces of wire

So to set an upper and a lower limit on one ADC port you need 2 potentiometers with wire.

You need to firstly solder the 3 pieces of wire to the three pins on the potentiometer.

Choose which limit you want to set and to which ADC port, then replace the jumper indicated in this picture with the potentiometer.

You can connect this either way round BUT the middle lead MUST go to the middle pin.
