happy new year,
I have got my dad to get me some old volt meters from the bay, theese ones **broken link removed** but i am not sure if i need a resistor (i am pretty sure i do) to make them work without blowing them up. My aim is to have a go at altering the weather thing i made mum and having the output show on the meters and i have seen the clock on here with old meters. so how do i make the meter go from 0-fullscale?? do i put a resistor in parallel with the terminals to limit the current? the voltage i want to use is 5v for max scale. i hoipe i have made it clear??? the output is pwm from micro (sfware pwm). thank you for looking.
p.s tell dad they were a bargain please he thinks they were expensive!
