Logic Behind Displaying Texts in 16*8 LED Display (Part 4 of 13)

<<<<  Read previous part (Part 3)

          We had completed the circuit for 16*8 LED display. Next is a step by step procedure to display the word "HE" in the 16*8 LED matrix as shown in the following image.

          LED matrix works based on the principle of persistence of vision. That is, when some frames are displayed one after another at a high speed, our eyes will feel that all frames are displaying together because of persistence of vision. Frames used to create "HE" display is given below.

          When these frames are displayed at a high speed eyes will get "HE" feeling. Next is to write an arduino program that will generate these frames and display one after another at a high speed.

  1. can u send me the whole code for this

  2. This information is meaningful and magnificent which you have shared here about the LED display circuit. I am impressed by the details that you have shared in this post and It reveals how nicely you understand this subject. I would like to thanks for sharing this article here.

All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
