This is almost a more general electronics question, but I would like to have the frequency of a tone, picked up by a mic, inputed into a picaxe chip. Does any1 know of a way this could be done easily? Thank you

Hi, I read about doing this in a book... And i'm sure there are loads of threads about it - I have had a look, and couldnt see anything. I'm looking for chip I can send a serial output, from a PICAXE chip, to and it converts the 8 bits I output into 8 digital outputs. What's its called? Thank...

Would this kinda of idea work? i know i might need another resistor here and there, and not too such about the resistance of the 1 ive put in. Basically, you press the PTM button, which turns on the transistor, effectivly turning the circuit on. As long as the output pin connected to the...

I am trying to design a program to display the amount of time i have been on the phone for, as i get free phone calls or an hour and always seem to forget and just go over (lol). i found a simple circuit to put an LED on when the phone was off the hook, and was going to use this as an input...

sorry about this

hey, the PDF on the PICAXE Manual, it says that pins 11-18 on a PICAXE 28X are, not only inputs 0-7, but can be use as outputs C0-C7. how do i use these? when i cant find anything on this on the web, and PICAXE Programing Editor gives me an error when i use C0 as i would use output 0 (high 0)...

I have been looking through some posts here, but all the speech synthesizer chip s mentioned, i cant find a single supplyer of one. I am looking to buy just one. I am looking a chip that i can use with a PICAXE, to speak, and a number of places say it's possible. This is for my Systems and...
