rotating led display that shows infinite words| pov | propeller display - display led

Watching the full video tutorial on the youth LED display is an amazing, very simple project that you can easily send to your special person.
The rotating LED display is also called the POV display.
This project is made with Arduino Nano.
The Arduino Nano is very small in size, cheap in price and has programmers on board so no external programmers are needed.
The Arduino Nano is friendly to the breadboard, so this is a positive point.
The rotating LED display or POV display is a rotating LED display with the LED flashing according to the letters, which makes some visible words visible.
The work of the "rotating LED display" "POV display" or "rotating LED display" shows the complete work, which is just an eye deception and our eyes cannot distinguish between very fast movements.
In this "pov display" LED light strip, the rotation speed is very fast (
Above 500 RPM)
The Led makes the pattern according to the letters so we can see the words or letters.
In the GIF image, you can see and understand how the rotating LED display works.
Let's say we want to display the letter "a" on the POV display, as shown in the figure is a GIF image. Some LEDs in the first column glow, and LEDs glow according to the alphabet.
After a few milliseconds of delay, the LEDs in the second column glow, and the LEDs are very fast, so we can't differentiate the changes and only see some letters.
In the rotating LED display, the Arduino Nano is used as the control unit.
Arduino is a micro-controller board that controls LEDs and forms a flashing mode.
1 pair of ir led (Infrared LED)and PD (Photodiode)
Used to determine the starting point of rotation.
When the circuit of the POV display goes through the white strip, the photoelectric diode detects it and starts the LED strip according to the letter, each time it makes the same pattern so that we can see the letter clearly
Eagle BRD File: please visit our POV display website is very simple, but we need to make it as compact as possible because it runs at a very high speed (
Above 500 RPM)
The motor can't handle the larger circuit, so I designed the circuit on the Eagle CAD software, which can make the circuit very compact.
If you are good at PCB etching, you can make your own PCB, click here if you want to learn about PCB etching.
If you would like the PCB to use the circuit given below or you can purchase from us, please contact us if you are interested.
If you are not familiar with PCB etching . . . . . . Don't worry, you can make the circuit on the zero PCB using the circuit given below.
In the POV display circuit, seven LEDs are connected to the Arduino pin (D6 to D12)
330 ohms through resistance.
A 10 k ohm resistor is connected to the photodiodes of Vcc and GND, and the connection points of the photodiodes and resistors are connected to the Arduino's pin A7.
Ir led connected to Vcc and GND by resistor 330 ohms.
