Purpose:
Create a position sensor using LEDs.
Goal:
Increase or decrease a pulse width in response to direction of movement.
Chips Involved:
1) Clock.
2) 2x DM74150 (16×1 Multiplexers.)
3) 2x SN74193 (4-bit Binary Counters.)
4) 1x SN74LS112 (Negative Edge Master Slave JK Flip-Flop.)
5) 1x SN74LS122 (Retriggerable Monostable Multivibrator)
6) 2× 7404 (Hex Inverter {Technically, I only need one chip.})
7) 1× 7408 (4 × 2 input AND gates)
In order to sum up what I’ve already concluded… I’m looking for an incremental encoder.
I just need help figuring out the flow of data. What is happening first, second, third, etc.
I hope that helps explain what I need help with. Again, I would be most grateful for anybody’s help.
I have done enough preliminary research to have a basic idea of how things are supposed to work. However, I’m trying to understand the underlying principle of operation (stated above)
Thank you
