Even though not strictly necessary for the final project we will also use an RGB LED. This will be used in an intermediate step where we will display the color read from the TCS3200 color sensor on this RGB LED. |

| | Since the Raspberry Pi GPIOs all work on 3.3V, the HC-SR04 as well as the TCS3200 however work with TTL (5V) logic, we need a level converter to bring down the sensor signal levels from 5V to 3.3V. This can be done either with a voltage divider using 2 resistors or with this level converter
