Filter switch board

This board is a rotary encoder, converting the position of the rotary switch to higher and lower resistance. This connects to the Primary HAT, via the Analogue to Digital Convertor. This allows the Pi to receive changes of state from the switch.

Components

• Perf board (10x24 holes)
• Rotary Switch with minimum of 6 states (I used Taiwan Alpha SR2611F020638F5BD Break Before Make Rotary Switch 2 Pole 6 Way)
• 2.2kΩ resistor
• 47kΩ resistor
• 100kΩ resistor
• 2 220kΩ resistor
• 2 470kΩ resistor
• 1MΩ resistor
