    14 m chip coding

    I am new to this, be kind of my lack of knowledge.. I have been using 14 m2 chips. I picked up some 14 m chips cheap. I noticed the pin outs are different. Is the way I both code and wire a toggle switch to pin 1c the. Same for both chips? Thanks for the input

It works perfectly. I plug in the servo where the leds were wired. test it out and nadda...unplug the servo and...

    toying with an idea and would like some input

    I am a model railroader in n scale. In n scale 33 ft is one scale mile. I want to determine how fast a train is going. My idea is to put a photo resistor under the track and 33 ft away a second photo resistor. When the train passes over the first sensor, it would start a clock and when it...

    I am new to this need advice

    I feel like a 9th grader asking a Dr. of math how to slove 2x+1=5. I replaced the "goto" command with the "gosub". ran the simulation and got a stack overflow - more gosubs than returns I did not get that with the goto commands. not sure why. i will post full code with no explanation and...
