Transpotter build from Lucy and Jana

:electric_plug: Wiring:

• Connect the potentiometer VCC to 3.3v from the programming port or from a voltage regulator, ⚠️ Red wire from the sensor cable delivers 15v !!!
• Connect the output of the potentiometer to the blue wire (ADC1) for distance and green wire (ADC2) for steering on the left sensor board cable
• Connect the potentiometer/hall sensor to ground, ⚠️ On some boards, the black wire is 15v !!! Check with a multi-meter to make sure 15V and ground are not swapped
• 100k Pull-down resistors connected to ground are recommended to prevent issues when inputs are floating (wire is cut or disconnected) triggering ADC protection

:gear: Configuration/Parameters

Voltage Control Mode is used by default.

How To Use

Power ON

Power on the Transpotter with a short press to the power button.

Cable length

A short press of the button will increase the distance of the transpotter to around 0.25m. Minimum distance is 0.5m, maximum distance is 2.5m. When pushing the button at 2.5m it will switch back to 0.5m. The chosen distance will be given out with a short beep in different frequencies. HIGH beep = short distance ; LOW beep = long distance. The chosen length will be stored in EEPROM and reloaded after each reboot.

Switching OFF

To switch off the Transpotter, press the button once short and directly afterward a long press. When releasing the button, the Transpotter will switch off.
