Hello,
I'm wanting to build a little circuit, where I can preset the number of turns for a motor to turn & when the pulses received from a tach pulses from that motor, the motor stops. (this is an overly simplistic explanation, as I envisage there being several counters all working of the same tach feed...also up to 8 pulses per revolution).
Now I'm new to logic gates (ok, so not completely I know the basic truth tables of the various type of main gates!), & I want to put in an order for some parts.
i know I'll likely ultimately need a BCD chip or two & perhaps a decoder, but this project aside, I was wondering if anyone had a good 'stater' list of the more common logic chips (ie by device number)...this would help me greatly in formulating my first parts order!
for example
Logic Gate Starter kit...
4000 Quad Nand
4516 BCD
4028 Decoder
etc etc.
