Pseudocode for controlling the air valves
Light sensor is in the place of motion sensor. Green led is the air OUT valve, the red is air IN.
Yellow led in the middle represents the air pressure. Bright: high pressure (cushion filled with air). Dim: low pressure (minimum pressure in the cushion).
When there is movement (light on the sensor), more air is pumped in (red led on). Otherwise the other valve starts to let air out (green led on).
