and the other servo’s signal wire directly to Arduino pin 10, as shown in the circuit diagram in Figure 10-4. 3. Connect the GND from the joystick module to the Arduino GND rail, and +5V to the ...

is applied to D2 input of the Arduino. Analog output (marked as AO) from the module is not used here. Sensor-head of the module contains two probes in a small metal pcb. When the sensor-head is ...

and it was obvious that it was not well engineered at all, so any attempts at fixing it would be pointless. Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module ...
