Electronics
The Raspberry Pi pico control board will have to control the whole system.
Further components
Optional elements could be:
- further sensor boards such as:
- a buzzer which works well around 4 kHz (C8 = 4186 Hz)
- an amplifier and loudspeaker
- a monochrome OLED display
Laboratory equipment
The developers should have access to:
- tools (screwdrivers, pliers, ...)
- a multimeter
- a welding station
- micro-USB cables
For test purposes, the sensor boards can be assembled in a chain with stemma QT cables and controlled via USB with the help of a general-purpose serial bus adapter.
