| As shown in figure 12, there is an Arduino Nano used to operate all components. The 14 digital I/O and one Analog Input of the Arduino are used to drive the servo motor, to power the LED and readout the reed switch. The servo motor and Arduino are directly powered by the battery. To control the servo the digital output D2 is used. The three single colour LED and the two RGB LED are connected to the digital Outputs D5-D12. To limit the current in the LED to a safe value, every LED is serial connected to a 330 Ω resistor. In addition, the reed switch is connected to D12 which is set on pullup. In case of a closed reed switch the digital pin is directly connected with the GND. | As shown in figure 12, there is an Arduino Nano used to operate all components.
