Project number 22 LED Matrix Display

91.87mm * 100mm ,Thickness:1.6 mm, 2 Layers, Finished Copper:1 oz

Basically DOT matrix is a LED Display arranged in such a way that to turn the led (x, y) it takes a combination of voltage between Pin row & column. LED dot matrix is a very popular means of displaying such information that allows both static and animated text and images. I found them at gas stations displaying gas prices, or in public places and along the highways, showing ads on large dot matrix panels. In this experiment, I use a monochrome (single color) LED dot matrix and interface with a microcontroller to display static characters and symbols. It may include animation stuff. cool, pcbway send eleven pieces. bonus one pieces. of course include free univers4l PCB 3x7cm  2x8cm  in box. In the dot matrix display, some LEDs are wired together in rows and columns. This is done to minimize the number of pins needed to drive them. This 10 × 10 matrix LED will require 100 I / O pins, one for each pixel LED. By wiring all the anodes together in rows (R1 ... R10), and the cathode in the column (C1 ... C10), the required number of I / O pins is reduced to 20. Each LED is addressed by row and number of columns. In the figure below, if R4 is drawn high and C3 is pulled low, the LED in the fourth row and the third column will be turned on. Characters can be displayed by either a quick scan of rows or columns.

how to simply repeat order to PCBway

Gambar
After my PCB Project completed. Here my Arduino board i spread to my friends. One of them is Mr. Chandra built that Arduino Board with all of parts. Thanks to you "Mr. Chandra". Let's mark this PCB with QC Passed sticker. The next question is "how to repeat order to PCBway ???"  Log in into pcbway.com and choose sidemenu : active order - completed. Click that and the form show like this below. Click Repeat Order, just simply step fill out the number pcs and duration (cost) fabrication type, ordinary $10 or Epxress (move expensive)  I choose ordinary in 2-3 days process fabrication. Click submit. ok thats is Wa are done order. NO need re-upload gerber files just wait for audit design. Unfortunatelly i cannot change my green board into cool color white or red board in this form. perhaps PCBway can do that for me. please.... :-)
