- The TOUCH SENSOR circuit allows you to connect conductive elements, especially metal surfaces, directly to the DART controller.
- These elements will react to the touch giving the possibility to control MIDI messages, as if they were buttons.
- the Touch condition is verified by sending a signal from the emitter pin 8 to the receiving pins 7 and 9. the capacitance of the human body is capable of delaying this signal, allowing to determine the Touch_condition_ON and the Touch_condition_OFF.
- The circuit is very simple and only requires the use of two 680k resistors.
