I'm going to take a 5V 500mA power supply and pass it through a digital potentiometer AD5235 and then step it up through an op-amp with a gain 2 to get up to 10V output and put that into voltage based ...
I wonder if unused pins of an IC, lets say an NE555 f.e., should be connected to ground via a resistor to prevent noise or not. I have an AVR with analog inputs and just realized there's huge noise, ...
can the control voltage pins 3 and 11 on the 556 timer use the same capacitor to ground? I assume that I can double the capacity of the 0.01\$\mu\$ capacitor to 0.02\$\mu\$ and share the capacitor ...
