Gas gauge calibration unit

I understand that. I always have more projects than time.

Bump!!!

Out freaking standing...

I must ask for 'schooling' though, I understand the need for an a/d
convertor... & a Pwm POWER SUPPLY...

Please educate Me on 'gain' & 'offset'...

I understand P.W.M. pulse width modulation...

Thx !!!!
