I see it all the time - robotic students go into infinite loops turning nuts this way or that or strip the threads on every project presented to them. This kid finally reveals the secret to screwing in not only a light bulb but bolts, etc. I know some adults who could use this, too.

I'm interested in showing some kids how the PicAxe might be applied to some entertaining attention-getting projects, and since Halloween is coming up in the US, I thought some video demonstrations might do the trick. I'm especially interested in seeing the effect (for example, a monster moving...

As part of learning about the PicAxe, I've been tinkering with using two Picaxe 14M2 chips to play a song using the tune command. I programmed a "master" chip to play the melody and a "slave" chip to play the harmony. I thought I could use a single wire going from one chip to the other to...

There are two "eyes" on the ultrasonic sensor and I'm just wondering if one is an emitter and the other is a receiver or if they both emit a pulse and then both detect the pulse as it returns. It's a simple question, but I haven't found anything answering this question in any of the...

The Tune Wizard is very cool, but because most music has repetitive units, I was wondering if there's not an easy way to copy and paste segments of music in the Tune Wizard. I've tried control click, shift click, etc. but at least on my Windows 7, I can't seem to get segments of the music to...

I'm trying to run a very simple program on a 14M2 chip to play a tune I downloaded from the ring tone files on the picaxe website. The downloaded text file for the ring tone looks like this: (IndianaJones:d=4,o=5,b=250...

On page 230 of the PicAxe Manual 2 for the sleep command it says: "Some PICAXE chips support the disablebod (enablebod) command to disable the brown-out detect function. Use of this command prior to a sleep will considerably reduce the current drawn during the sleep command." I was wondering if...

Recently I've been looking at ways to get one PicAxe to talk to another PicAxe in an outdoor environment. I've been looking at cheap 433 MHz radios (like what are used on garage door openers). These would use a serial type communication at low (600) baud. All seems well, except I've noticed...

To save battery power, I plan on having my 433 MHz radio receiver turn on only when needed, but I noticed that RFIN is a blocking command that appears to have no "time out" feature. Is that true or am I missing something somewhere? If such a timeout feature is needed so that the PicAxe can...

I've been reading over older posts in this forum on the use of the Dorji 433MHz modules and they look very attractive, especially because they can use voltage supplies other than exactly 5.0 volts. But I haven't found a source for them in the USA and I've also heard people mention that their...

I'm new to the PicAxe and I've never worked with any RF communications before so I was hoping somebody here might have some tips about using Sparkfun's 434MHz RF modules or something similar to them: www.sparkfun.com/products/10534 www.sparkfun.com/products/10532 EDIT: NOTE: Please see post...

I would like to run a battery-powered PicAxe with as little power as possible. As I understand it, running the clock as slowly as possible is one way to reduce power consumption. On the M2 parts, the clock can be set down to 31 kHz by using setfreq. However, I would like to have my PicAxe...

Greetings, I'm totally new to the PicAxe world, and except for the "Code Snippets" category on the forum, I haven't been able to find something like a large library of often-used code examples, such as what might be used with LCDs, a compass or altimeter, or for controlling various external...
