    28X/40X Protoboard?

    I recently bought a 40X chip to help handle all the tasks I throw at it with my roller coaster model. Now I was trying to make my own custom circuit with the 40X (and download circuit) on a piece of stripboard. Unfortunately the wide size of the chip will not work with the patterns on the...

    28X + H-Bridge?

    Well this is a continuation of an H-bridge topic I made a few months ago. I finally bought most of the parts and have a few questions about their integration. Just a little background on my project. I am building a model roller coaster with a launch section. I am using the 28X (in the 28 pin...

    Sample LED Circuit and More?

    So the first test I did when I got my PICAXE chip/project board is the LED test with the LED and 330 ohm resistor on output 4. I just wanted to know exactly why you connect the LED between the V+ and output pin? Just trying to figure this out so I understand it for hooking up 4 LEDs in parallel...

    Another H-Bridge Topic

    First off, I know there is a H-Bridge topic out there already...made by useless. I have read every post, but since his motors are much ligther duty that mine, most of the suggestions in that topic don't help me. Thus I made this topic to not impose on his... My motor is the Traxxas Titan...

    pwmout ?

    I've searched the archives and read the entire monual on the pwmout command with a 28x chip yet I am still confussed on what to do. When I use the formulas in the manual I usually get #s less than 1 or larger than 5000000, or so. What am I doing wrong? Are the duty cycles and period values in...
