Dot Matrix Printer from a CD/DVD Reader with Arduino Tutorial
Check out this creative tutorial from Robson Couto on instructables and learn how to build your own Dot Matrix Printer using an arduino!
Hey!
Some time ago while going through the pages here in Instructables, something catch my attention, a printer made of a CD reader, and i was amazed.
I thought: “This is incredible, I have to make one!”
I know that these kind of projects don’t always receive a “I made it”, because of its degree of difficulty, so i tried to make mine easier.
This project was started more than a year ago, because of the lack of time i could only work in it while on college recess, but this is great because I finish it during the remix contest, that’s fit perfectly in this case. If you think that I deserve your votes in the contests don’t be shy and hit the button, I really like your support.;)
I also wanted to make this a motivation, i don’t even dream of putting my hands in a laser cutter or 3D printer for making my projects, so i made this printer only using my dremel to cut the plastic pieces and gluing them together with super glue.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
