First time posting...here goes I have been trying to make a hardware counter for an encoder for a while, basically I want to not rely on the Arduino to capture the pulses, I was thinking there must be a way to count pulses with a counter chip and poll it periodically with the Arduino. I found this …

I think you'll be better off with software. Use one pin connected to an edge-triggered interrupt (rising or falling, doesn't matter). In the ISR (interrupt service routine) check the other pin. If it's LOW, increment else decrement. When using the counter, disable interrupts briefly. Be sure declare…

Post the schematic as you wired it. Perhaps there is a simple wiring error.
