Hi, I'd like to be able to measure the delay between 2 audio pulses (e.g. hand claps) ideally in milli seconds using a picaxe e.g. 08M2. I have the hardware and microphone sorted, but need a pointer with the code. Can this be done? Thanks in advance. Mike.

Hi, The code below runs OK when the Picaxe type in the emulator is set to 20X2 or higher BUT, returns a syntax error if the Picaxe type is set to 08M2 !? I'm running the latest emulator version 6.0.8.0. What am I doing wrong? Thanks in advance. Mike. LET b0=247 LET b1 = b0 DIG 0 '...

Thanks AllyCat! I've tried this on a breadboard and it works well - re setting the CD4026, as this is obviously a very high impedence input. I used 100k pulldown. And am using the freed up C.4 for the sounder. I've attached a revised circuit. :) Cheers, Mike.

Hi, Thanks for all your replies! Sorry I meant pin C.4 (leg 3), in my original post, I'm not using C.3 in, probably needs a pull down resistor? I've inserted a circuit diagram. I agree using the bigger 14M2 is the way to go, I was just trying to push it as far as possible and only have 08M2s...

hi, I'd like to use port 1 (pin 6) on a Picaxe 08M2 as an ADCinput using a thermister and resistor potential divider, BUT also use this pin to beep a piezo sounder. All the other ports 0, 2 and 3 are tied up with driving a seven segment display. Port 2 and 4 to reset and clock a CD4026 driver...
