Here’s an example of a project that uses a 5×7 matrix and time mulitplexing: I have not done it yet, but you can address 5×7 matrix’s using a maxim max IC. Have a look here: Ashish Mehta depicts We offer prompt technical support, comprehensive data sheets and help customers choose the right product for their applications. Please enter your Email ID. If you do this fast enough, it will look like they’re always on. In this case, all of the anodes in a column are electrically connected, and all of the cathodes in a row are electrically connected or vice versa, depending on the model.

Have a look here: Not sure what’s wrong with your code, but I might have a simpler solution for you.
By contrast, the versatility of a dot-matrix arrangement allows an LED unit to display complicated shapes. To accommodate the 5×7 LED matrix on a solderless breadboard, two of them are required for proper mounting of 5xx7 optoelectronic display.
I have just ordered an arduino and have the max chip sat beside me. In other words, make sure the hardware is working with the simplest code you can.
Building Raspberry Pi Controllers: To control all of them, you’ll need to switch each column in sequence, changing which rows are active. Now, let’s build a working 4-bit binary counter. Number of Employees Upto 10 People.

5×7 LED Dot Matrix Display | NightFire Electronics LLC
Mother nature has been generous to boon us with all these in full abundance. We are here to help! LEDs are often arranged in patterns to display information.

5×7 LED Dot Matrix Square Dot
I used a le similar 5×7 matrix on Arduino a while ago. How to scroll a character across the display? So does our needs, requirements and applications. Join Stack Overflow to learn, share knowledge, and build your career. Here we put the letter A on the display as you can see in video, using a breadboard.
You don’t care about multiplexing or other complex controls. The magic behind an electronic counter is based on a cheat sheet called binary weighted values. I’ve included a video clip showing the counter in action provided below. The digital matgix circuit provides a series of repetitive pulses, or square waves, for proper time sequencing of an electronic device.
