The current coming out of my 600kilo-ohms voltage divider is vary low.
This voltage is to be read by a microcontroller(picaxe)
The problem is that the microcontroller can only read voltages with 10k impedience with accuracy.
So,I nead to increase the current, but not the voltage.
Beaniebots told me Op-amps can do this.
I didn't think they amplify current.
Do they amplify voltage and curent, and then do I run another voltage divider after the Op-Amp? (I know nothing about OP-Amps)
I must use the primary 600k divider network!
Thanks
