Arduino Mega: PWM Pin and Frequency Timer Control

Arduino Mega: PWM Pin and Frequency Timer Control

LOTS OF NEW UPDATES! These have all been personally Measured By Myself!!


Want to change the frequency on your your arduino mega?

I have painstakingly Spend many hours today going through every timer one by one and checking them on the Oscilloscope.

I can now accurately say these are all guaranteed within .05% precise… 

A lot of this info is out there on the web but not much of it is all in one place and as easy to find as right here VS. Arduino’s Forums.

Getting all this data together for my projects has taken me much effort since a lot of it was hard to completely understand when every place said refer to the datasheet.
That’s great! The french in the data sheet says yes there are timer’s and yes they can be changed, but there was no dumb dumb version in there to say , Do this, Type this here.

There is a lot of info on this for other boards like UNO etc…. but they don’t work the same on the mega’s.

Ok So…..

Clear Glass PCB’s

Jeri Ellsworth just shared a post about how Charles Lohr has developed a method for making glass PCB’s.  Charles  goes step by step in how he makes a touch controlled LED board.

This Is just ,just Hell there isn’t a word, GEEK-TASTIC. How would you use a clear PCB?

I’m thinking maybe a LED Matrix Cube With the circuits around the Outside. That Would BE epic.




Update! Corrected Datasheet…..

These are a nice Led Dot matrix I found on ebay. I picked up 12 of them for around     $14 US.

The leds are 8×8 and the total size is 32mm x 32mm.

If you want alot of leds in a small area these are great.

I bought them to use with an arduino for a led sign I was making. The only problem I ran into was trying to find a good data sheet that was also in english.

So I painstakingly Made one. You can get it below. Enjoy!

I have run across several Forums where people were all  bummed about getting these said they didn’t work with Arduino’s matrix Libraries.

Well I’m here to confirm that in fact they do work with arduino led matrix libraries and 74595,  Max7219/7221, AS1107 chips just fine.

That is after you use my datasheet and not the crap ones everywhere else on the net to wire them up correctly.

Your welcome Sobiguy OUT!

Found this on the Nets today. Had to happen sometime.

Still You have to recognize to potential this will undoubtedly lead to. T-shirts with your own graphics or logo this epic!!!!

This got me thinking. Now I what to build my very own RGB LED Screen. And I Want to do it on an arduino.

Can it be done?  Who cares!  Where there’s a will there’s a way.

JOS- Arduino TFTLCD Menu Interface Mega support

JOS- Arduino TFTLCD Menu Interface Mega support

Jeremy From Writes:

JOS stands for Jeremy’s Operating System and is open source. I encourage you to use it, hack it, and do what ever you want with it. I know some might say “it’s not an operating system!” I know, but it’s just a name. It is based on Lady Ada’s TFTLCD and TouchScreen libraries. It shares some of the code from Lady Ada’s tftpaint sketch found in the TFTLCD library. It is written in the Arduino IDE and works perfect with the 2.8″ TFTLCD breakout board and the Touch Shield. This version does not support and SD card/bitmap functions as I do not have a touch shield yet. I will write these in when I get a Touch shield some day.

This was already A great piece of code Jeremy over at created.

After giving it some trial Runs. I could instantly see the potential. Tho It worked great if you are on a uno board or the ATmega: 168/328’s.  I found out quickly it wasn’t up to the task of running on a Mega 1280/2560. Which I myself use most of the time.  Thus started my quest for improvements.
