LED Cube using 555 Timer and CD4020 IC CUBE without any microcontroller:
There are many types of cubes that can be designed. The simplest one is LED cube.
This LED CUBE is made up of 27 LEDs (Light Emitting Diodes),
these LEDs are arranged in rows and columns forming a cube. Similarly we
can make LED cube and and higher no. of LEDs.
LED cube the work almost triples because you need to do work for 64
LEDs. With each higher number, the work almost doubles or triples. But
every cube more or less works on the same way.

Normally for controlling an LED CUBE, we use microcontroller and
programming for getting different patterns. But for beginners it’s a
complex process, so here we are using the combination of 555 Timer and
CD4020 IC which is best suited for beginners. Although with this circuit
we can only get one pattern, but this is the best way to get familiar
with LED Cubes and their working. Learn more about 555 Timer IC by
checking more 555 based circuits here.
LED Cube using 555 Timer and CD4020 IC CUBE
LED CUBE by 555 timer is simplest because there are some advantages to this design like,
- For this cube you need not worry about power consumption or dissipation.
- Low Power supply demand.
- We don’t need any switching electronics like transistors for this cube.
- We need lesser logic terminals so we don’t need shift registers or anything like that.
- No programming needed.
- No need for complex circuitry
- Basic circuit knowledge is enough to design this project.
Components Required:
- 1KΩ resisters (10 pieces)
- 27 LEDs
- 555 Timer IC
- CD4020 Binary counter IC
- 10K Pot
- 10uF Capacitor
- 5v Power supply
- Soldering tools for building LED Cube
Circuit and Working Explanation:
Here we have used the same LED cube which we have
previously used with Raspberry Pi, and the building of this LED Cube is
explained earlier in that project. Please check below two projects to
properly build the LED cube by soldering the 27 LEDs in particular
order:
As shown in picture, we have a total of 12 pins from the CUBE. Over which 9 Pins are Common Positive and 3 pins are Common Negative Terminals. Remember each column represents a positive terminal and each layer (row) represents a negative terminal.
Since we are only controlling the LED CUBE by
CD4020 counter there will be no controlling needed at negative
terminals. So we have grounded all three common negatives as shown in
the circuit diagram. With this we will have 9 positive terminals from 9
columns of LED cube.
