Hey, I'm new to electronics, and for one of my projects, I'm supposed to design an Ultrasonic Rangefinder using Analog components only!
The components include the 555 timers, SN74HC chips (specifically the 4 bit counter), 7 segment display and etc.

Most of the guides I have found online use an Arduino. So, I was looking for some guidance that might be available on how to build the circuit? How can I get started or if there's any online guide available online?

Thank you
