Testing the PICAXE-28X CPU

Wow, I am a convert of using PICAXE chips They are so easy to use!

Close up of the test circuitry.
I have played around with measuring voltages (hence the red variable resistor), switches, LED's and (not shown), reading DS18B20 temperature sensors.
I should also be able to get rid of having to use the Northlight Digital Servo controller, and connect the Servos straight to the PICAXE chip.
One of the web sites listed in the great PDF manuals that come with the Programming Editor, listed connecting a CMPSO3 compass via the I2C bus IO pins. The compass looks to be cheep with 3-4 degrees of acuracy. Wish I and found that one earlier. One for the web sites (robot-electronics) lists a lot of cheep modules you can connect to the I2C bus.
Well, I might take a break from all this for a while. I think I will work out in the shed, working on building some walls and a clear plastic front to my yellow PC board. I would like to be able to take it out to one of my favorite camping spots, and take some GPS readings.

 

Here is the test circuit diagram:
