24 × Force Sensitive Resistor One for each colored circle. I used ones with a 1.5" square target area.
24 × 1k ohm Resistor To create voltage dividers with each FSR
3 × MCP3008 (8 channel, SPI ADC) 3 X 8 channels == 1 channel per FSR
1 × ESP-32 Dev Board Any should work, but you'll need access to default SPI pins + 3 Chip select pins (I think you can use any GPIO for these)
