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

 

Do you know how a Range Finder works?
Will give you a couple of keywords - Transmit, Echo, Time.

 

Is this a school/college/workplace assignment?

 

Since when is a 4-bit counter an analog component?

Just a note: 74HCxx chips are not analog components. They are digital. I assume that you mean that you can not use a microcontroller in your project.
I recommend that you start with the inexpensive HCSR04 ultrasonic sensor:

It's a school project

Apologies, what I meant was we are not allowed to use any microcontrollers.
