Arduino PWM Interrupt Clock

Using the milli() function in order to do accurate timing on the Arduino doesn’t work because it shares the same priority in code execution as any other code. I wrote a blog post that talks about using PWM and an interrupt in order to create a much more accurate clock. In my post I talk about how to wire the PWM to the interrupt and how to use the Adafruit 2.2 inch TFT LCD to display the time. The full post with pics, links and demo code is here:

I also recorded a video of it in action:

Wifi Temperature Monitor using an Arduino Nano

My plan here is to use the $9 Arduino Nano and the Roving Networks RN-171 serial wifi to make a wifi enabled sensor that can post to the cloud. First step i had to do was solder some legs on the smd wifi chip. These pads are small but you can see in the pictures that i have 4 legs now: tx, rx, gnd and 3.3v.



I put this new setup on a breadboard so that i could reconfigure the pins as needed. I like this sort of “dead-bug” construction.


Next up I have to communicate over serial with the part and has a lot of questions about the best way to do it.  For now I am toing to use my FTDI Basic USB from and teraterm at 9600 (from the user guide). Ill let you know how it goes.

Headtracker new video with actual gameplay

My latest demo video of the IR Cam Headtracker:

This is actually not the latest version of the controller software.  I have made a few revisions since posting this on youtube that eliminates some of the jerky movements and gets rid of all the mismatched Bytes (coming from the camera).  The end results is a lot smoother than you see here.  Right now I am working on putting the Max Power IR LED’s into the headset in the hopes that I can extend the distance between the headset and the camer (right now my max distance is ~1 meter, and i need it to work as well at 2 meteres for larger TV’s).
