Hi guys! I need some advice, I need to measure a motor's speed with a tachometer and get an analog output (voltage), but I need it to be proportionally inverse to the tachometer's frequency. The higher the motor's speed, the lower the voltage output. Is it possible with nano? Thanks!! -Carol.

Tachometer to analog output

Sorry I haven't been clear enough!
I need a simple DC output, but inverse to the tachometer's frequency
