Most often than not, hobbyists will build a clock generator for their projects. It makes sense to have a comfortable source of clock generator once you are past that milestone.
This is a breadboard-compatible clock generator module that outputs stable square waves from 0.5 Hz to 2048 Hz. Designed for students and beginners in digital electronics, it uses a 32.768 kHz crystal oscillator and standard CMOS ICs (CD4060 and CD4013) to divide the frequency and produce precise timing signals.
The module fits directly into a breadboard and provides multiple frequency outputs via easy-access headers.

What is it?This is a breadboard-compatible clock generator module that outputs stable square waves from 0.5 Hz to 2048 Hz. Designed for students and beginners in digital electronics, it uses a 32.768 kHz crystal oscillator and standard CMOS ICs (CD4060 and CD4013) to divide the frequency and produce precise timing signals. The module fits directly into a breadboard and provides multiple frequency outputs via easy-access headers.
Why did I make it?I created this module to help students and hobbyists learn the fundamentals of digital electronics like logic gates, flip-flops, and sequential circuits. While teaching, I noticed that a reliable and simple clock source was missing from most beginner setups. This module solves that problem by offering an accurate, low-jitter clock with a clear, LED-indicated 1Hz output—perfect for “blinky lights” and step-by-step logic demonstrations.
What makes it special?- Crystal-based accuracy using a 32.768 kHz timekeeping crystal
- Wide frequency range from 0.5 Hz to 2048 Hz
- Visual feedback via a blinking LED on the 1Hz line
- Plug-and-play headers for quick experimentation with different clock signals
- Designed and tested with real students, ensuring ease of use and reliability
- Protected and filtered input with reverse polarity protection and decoupling capacitor
Whether you're just blinking an LED or exploring edge-triggered flip-flops, this module is the ideal clock companion for your breadboard.
How to Use it?1) Plug the module in the breadboard, making sure the 5V and GND rails are connected correctly on the power rails. (There is a reverse polarity protection diode, so don't worry if you make an error).
2) Notice the LED blinking at 1Hz. If not, check if the black 2 pin shorting jumper is connected.
3) Plug a jumper wire into one of the provided headers for frequency outputs and connect it to your project.
4) Make sure both the module and the project share the same ground connection.
