    Connecting two outputs to one input

    Many thanks for your input guys, much appreciated. So after reading about diode logic (I should know this stuff!) as suggested by Buzby I have sketched a proposed solution, attached. The input to 18M2 is held low via R1 and R2 until either of the 08M2 outputs goes high. R2 acts as current...

    Connecting two outputs to one input

    Hi. I want to connect an output from two 08M2 chips to a single input of an 18M2 so that either/or of the outputs will trigger the 18M2 input. I understand that I need to place a 1k resistor in series from each of the outputs but that will mean the two outputs are then connected together with a...

    08M2 controlling 12v DC motor via L293D - Help!

    Hi, I have built the attached circuit but can't get it to work. If I place a high (5v) on pins 5 OR 7 (C0 or C2) (with the 08M2 removed) then the motor will turn in either direction as designed. But the 08M2 does not seem to be able to drive it. All I get is a slight twitch at each 20 second...

    Re-acting to Hex inputs

    Following on from my (hopefully) successful build of the mp3 player, I want to choose a track (from 16 available) to play by responding to a logical input across 4 input pins ie 0-F Hex. My idea is to use one of these to select the inputs then a separate input (push button) as a "trigger" to...

    SPE035 mp3 player

    Hi, First post here but been lurking awhile. After several years away from programming I have just restarted after another member on here introduced me to the Picaxe range of micro controllers. I had some (limited) success so far with playing with these things but have run up against a problem...
