I was just wondering about calibration circuits for phototransistors to account for degradation of the LED or phototransistor? Is that necessary, do they degrade quickly? Thanks
Good day, all
I have a small fan setup and I wanted to add a potentiometer to use as a variable resistor. I checked some steps of how to wire a potentiometer. I've come up with this design which uses a logarithmic potentiometer in place of a series resistor.
Initially, the red line did not...
I would like to place a non-polarized capacitor in between V1 and R1. Is it possible to replace the non-polarized capacitor(ceramic capacitor) with two polarized (electrolytic capacitors) C1 and C2 shown in the diagram above?
I have a very simple circuit on a breadboard with two push-button switches, an AND gate (74LS08), and an LED. I have the two switches hooked up to pins 1 and 2, while the LED goes from 3 to ground. Pin 14 is given 5 volts, while pin 7 goes to ground.
I'm just trying to test to see if the AND...
