Hi, i am new in analog designs. Now, i am trying to design a circuit using STC(Schmitt Trigger Comparator) circuit to monitor the voltage level of a car battery which normally is around 12 volts. Im trying to use two LEDs,green and red, to indicate the voltage level of the car battery. If the...
I have this circuit here and I want to know what are the threshold voltages and there derivation. This circuit is a bit similar to a circuit I did in the past but the equations still seem to elude me.
Ideally, i'm looking for a simple frequency divider that i can feed a square wave, using only schmitt inverters or schmitt NAND (just one if possible). Should work over a wide input-frequency range.
The posts below provide a schematic for a so-called "flip-flop" (which i think is really a...
I have recently been attempting to delve into the world of electronics and have been trying to build a very basic oscillator using the CD40106 chip. I have set up the circuit as follows:
9v to pin 14
pin 7 to ground
1 microfarad capacitor from pin 1 to ground
100k ohm potentiometer between pin...
Hi everyone I have assembled this circuit http://www.ecircuitslab.com/2011/11/normally-chargers-available-in-market.html
and after many trials I got it to partially work, the problem is that, I can't get the relay to de energize
it's a 6v relay with coil resistance of 100 ohm (instead of the...
