Making my own sensors
Eobody3 supports many kinds of sensors. Most common sensors are switches and potentiometers,
but there are many other kinds of sensors.
• Making my own sensor switch
(Connecting the ground avoids antenna effect when the switch is off)
Sensors need a minimum of two cables: ground and signal. When 5 V is connected to the signal -
when using switches for ex- ample - it may create an antenna effect generating undesirable
distortion. This is the reason why the signal must be connected to the ground.
• Making my own sensor potentiometer
To use a standard potentiometer with Eobody3, connect both outputs of the potentiometer resistor
to the ground and 5 V. Connect the variable output of the potentiometer to the signal input.
• Making my own sensor with other kinds of sensors
Some sensors like distance sensors need an extra power supply. Eobody3 delivers +5V and +9V to
power these sensors up to 250 mA. When the total consumption from all the sensors plugged to
Eobody3 is higher than 250 mA, an additional external power supply is necessary.
