I have built the following circuit, shown here:
The circuit first regulates the voltage to 10V using the 5K pot, the frequency is an adjuatable square wave with the 100K pot and is adjustable from 0-10kHz, the Counter, NAND, and AND gates have been set up so every 20th pulse will be blanked out.
After hooking up a light bulb as shown to the source voltage and the transistor I have the following problems.
The light bulb stays on constantly regardless of frequency!
I am only gettting 1.49 V to the base of the NTE11 and I think that might be my problem.
ANY help would be greatly appreciated to get this circuit working properly!
