Can I use the picaxe o8 proto board with a normal 08 picaxe chip? I have used a 08-m before but when I try a normal 08 picaxe it sais it does not support the device or something like that? could I have a blank pic controller? (If I have those people at sth is. communications are l*sers)

I have searched high and low on the internet for the piano keys for james bond theme so I can put it on my 08-m picaxe. I can't read music sheets (piano sheets) but I can understand C C# A B C etc etc and 1/4 notes and 1/8 etc etc. I need this by an hour please help if anyone can help if they...

Question #1 Does a picaxe 28X always have to have a 4mhz resonator and a reset switch? or onlt in the download circuit. Question #2 Im using the BS-C515RD 7 segment display but have no information on the pin-outs I have 10 pins and I know 8 of them are for the display itself (7 seg + dp) and...

Is it possible using the infrared reciever circuit shown in manual 2 basic commands and a simple res + led ir transmitter connected to output 0 to send a message via infrout then see if the reciever picks it up. ( the receiver and transmitter are next to eachother facing foward) if the reciever...

Can you turn an input off, So that it doesn't rrad anything or let power into it. e.g have led going from +v to input, can you control wether the led stays on or off?

HI, um This is my first ever post... lol, Um Theres a little challenge with a prize of lots 6000mcd ultra bright leds to the person who can turn the most leds on seperately (one on at a time) using a 08-m picaxe, naturally I'd like to win (sadly its a young peoples challenge so none of you guys...

Quickly reply, is there any difference between the two, I want to connect 2 together to use 2 7 segment displays can I do this with the 4033be? I want to use the circuit shown in the interfacing circuits manual 3.(in otherwords if I use a 4033be can I keep the same circuit in the same pins with...

You must be sick of me now. anyone know of anything that would be suitable as a ram to connect to a car window squirter pump, im trying to make my own little hydrolic ram kit. yes, another project

Has anyone used the (CAT. NO. KG9158) Ultrasonic Proximity Detector Kit B214 before? I was thinking about connecting it to a picaxe for a play-around.

besides numbers what else can you make on a seven segment display? is it impossible to do anything other than 0-9 when using a dic like the 4026be. is using alternative symbols only possible if all 7 segs are connected directly to the picaxe?

I had one of those days where I just feel like ripping something worthless apart and see what I could do with it, an rc car was my victim. I have a controller at 40.635MHZ(rndabout) and a reciver (at the same MHZ) in the car. the car drives two motors, each one either fowards or backwards. first...

I don't quit understand the random (wordvariable) command. what I want to do is generate a random number and then depending on that number perform a certain task (of five tasks) I understand that this command generates a number beetween 0 and 65335 so I would go something like: if w0 < 1200...

Im using two 7 seg lcd displays with two linked 4026b dec ic's (although this question applys to single combination aswell - 1 7seg + 1 4026b) as in manual 3 -interfacing circuits however I just have one question, where do the pin 0 and pin 1 pins go in the picaxe (im using 28x) out of the...

what do the 'out c1-c7' pins on the manuals for 28-40x chips represent, just more outputs? Edited by - useless on 18/08/2006 11:05:22

Can anyone give me an example counter module that is sold through the picaxe site (and sicom.co.nz) because the manual does not give any examples, also is it possible to incriment the counter by more than 1 each time or is a for...loop required to do this cheers

I need to use every single output and adc input on an 18pin picaxe (18x) So I want to use a PICAXE-18 Standard Project Board (CHI030) but is it true that you cannot use all the adcpins and all the output pins with this board? (like 2/3 or something?) Also when reading the manual the connections...

I am presuming that there is no code for generating random numbers on the spot but has anyone been able to get close or create the illusion that random numbers are being generated, cheers

I have a small 2 transistor amplifier for a speaker im using and it includes a 500k potentiometer log type as the volume control but all it does is keep it at steady volume for everything except the highest resistance when it turns off, is this normal, or should I be using a linear pot?
