2D Matrix display

Final Touches

Giving some final updates and verification to all the sections of the project.

In this devlog,

I finished writing my code and after verifying it I uploaded the code in my microcontroller [ESP32] after that I plug in my display to see if it works. At first, the 2nd col LEDs and the 4th col LEDs does not seem to work. Perhaps, it was my bad soldering skills. So, I started looking for leaks or I should say bad circuits. After some fixing, It seem to be better but still the 2nd col LEDs and a 4th col 4th row LED did not work. So using my multimeter continuity I eliminated some more troubleshooting and it finally worked like fantastic.

I updated my Readme and Github and I think it is ready for submitting.

That’s All.

In this devlog,

Finally, the hardware is done. I took a lot of patience and troubleshooting to get this right. I must confess, the soldering is not the best but it is under progress. I begin writing code for microcontroller in the Arduino IDE which I forgot to take the screenshot of.

Done

• Assembling
• Soldering
• Circuit verification for troubleshooting

Under Progress

• Writing Code
• Updating GitHub
• Testing
• Finalising

That’s All.

In this devlog,

So, It has been long since I last worked on this project. So, working on this gives me a long feeling. I suppose, this project has taught me a lot. Any way, I continued the assembling work and almost at the end. Made some minor file updates and also added a BOM.file .

Done

• BOM.csv
• CAD.file
• Assembling [Almost]

Up-Next

• Code.ino [ArduinoIDE]
• Testing

That’s all.

In this devlog,

I was planning to finish my soldering but it went wrong. Here’s what happened, I bought enough soldering wire for my project[The last picture below] and was ready to finish all the soldering work of my project. As I was working through, the worst thing happened, my Soldering Iron BROKE [the Tip]. I guess this project is gonna take long time.[There is a picture of Broken Tip too.].

That’s all.

In this devlog,

I continued my work by soldering the rest of the led’s pins[i.e. anode, cathode]. I did the best I can still I made some mistakes. Perhaps, I am still a beginner.
Now,

• Soldering [About to finish, Last phase]
• Circuit [Checked]
• Microcontroller [Yet to program]

That’s All.

In this devlog,

I started to solder all the components which I assembled in last devlog.

• First, I soldered all the anode pins of individual leds
• Secondly, I started to solder all the cathode pins of all the individual leds
• Then, I started to connect[solder] the anodes pins to make columns, that when my soldering wire ran out. Perhaps, I must have a good stock of it.

That’s All

In the devlog,

I add the other components which were not added in the previous devlog. I was confused between two resistors about their resistance so I just calculated it. I had a little trouble getting the components in the right place but I figured it out. So, this is how it looks till now. I think will work on the programming the microcontroller or maybe soldering the components in the next devlog.

In the devlog, I got all the components required and started the assembling process. Unfortunately I had to check all the leds before using them and turned out some of them were fused. I still have to solder everything and also code the esp32.

Final updates and changes to schematics of my project 2d matrix display. I tried making it more neater and organized than before. I removed all the excess text and other interferences. I think it is done. But I do think I have to make some changes after I make it physically [Maybe].

This Project is a continue work imported from macondo and will continue in stardance
