Topic: Arduino/Atmel development Board with LCD serial output (Read 997 times) previous topic - next topic

basically just a simple board with an lcd for serial output being driving by a separate chip so that the chip im programming is not deprived of GPIO pins.
i wanted to make it all from scratch and use all my own code, even to drive the lcd, no libraries .
i learned a lot after making this, well i learned a lot of things not to do.
not the prettiest thing in the world but it get the job done.

Looking forward to progressing with the design and making it better and definitely cleaning it up.

i do not know how to embed youtube videos

I could print the Arduino logo on a box of cereal and sell it as "Arduin-O's"

One of the members of this forum (Liudr) makes various serial/shield display units with available lcds and sells them through inmojo.  I believe the 16x2 and 20x4 serial units may be what you desire: http://www.inmojo.com/store/liudr-arduino-and-physics-gadgets/item/serial-lcd-back-pack---phi-panel/

As of this writing, I don't yet own a Liudr display, but it is on my someday buy list.

Dude! That board looks pro.

I was wondering if plastidip could be used like that - nicely done. It costs ~$25 / can here, so not something I was prepared to try on a whim. I think you guys pay something like $6 yeah?

To embed the video, just use the youtube.com URL rather than the youtu.be URL.

Well done, this is a great job. Multi-mcu boards FTW!!

I bought some I2C serial interface boards from Ebay to control some LCD screens I have with fewer pins. They use PCF8574 ICs.

Do you have plans for using more of the secondary 328's pins or processing power than just driving the LCD?

Nope not planning to use the second 328 for anything other then to just listen to the first 328  and print out what it says...it only for debugging purposes ..since I use atmel studio not the arduino ide getting a serial output window is harder so I just made this for that purpose.

Plastic dip is made by the same people who make liquid electrical tape...they just call the two products by a different name but for the most part its identical. A rubber non conductive and removable coating.
Yeah it was 6 dollars at homedepot
