Hi. I have a Bluetooth connection between my phone and a Bluetooth module connected to a 8m2 Picaxe chip and the connection is working. The thing is that the number I send is split into digits. The number I send is from 0 to 255. Both inclusive. Here is the code I use on the Picaxe: setfreq m8...

Hi everyone. I have been wanting to build Game of Life for some time now and recently I stumbled upon a cheap nice LED matrix http://www.taydaelectronics.com/led-displays/8x8-dot-matrix-led-display-red-3mm-common-cathode.html so I have decided to give it a go. I would like to get some input...

Hi. I recently got two Wi-Fi printers that got thrown out so I decided to take them apart and salvage what I could. I got some nice stepper motors and normal dc motors but I also got some Wi-Fi modules. Now my question is if I could interface those modules to a Picaxe chip without much hassle...

Hi. I have an application where I am using a Picaxe that spends most of its time off (battery disconnected). Once a day it is awoken by a button press that connects the battery to the Picaxe. This button can be pressed down from anywhere between 5 seconds and 10 minutes. While the button is...

Hi. I have a picaxe development board with an 18m2 Picaxe chip and I am trying to interface with an LCD module that I got from a different source. I backed a project on Kickstarter that was called Digispark and I got some LCD modules with my pledge that use i2c. You can see it here...

Hi. I have a logging project and I am trying to connect Openlog to a picaxe 18m2. I have the board connected to 5.2V power supply. I connect RXI on Openlog to C.2 on the 18m2 and I ground Openlog pin BLK. Here is my code: pause 5000 high C.1 ' Turn an LED on to see when it starts pause 100...

Hi. I have been programming picaxe chips for some years now but recently I have been getting an error message when I try to download a program to my 08M chips. I use those the most. The wierd thing is that I can download to my 20x2 chip with 100% success rate using the same, exactly the same...

Hi. I am making a project that involves a wireless communication using 433MHz cheap chinese wireless modules. I can't find the datasheet for them but I have them working without a problem. The question is if someone has come across a good way to make a reliable communication using one transmiter...

Hi. I have two computer fans and I am controlling them with a picaxe 08M. The fans are four pin fans, meaning that one pin is 12V, second is GROUND, third is output and fourth is input. I am using 12V, 500mA power supply model HNP06-120 and a 7805 voltage regulator to supply the picaxe with 5...

Hi. I want to be able to push a push button, the ones that are only on while you press them, and have the microcontroller keep it self on with software. I tried to make a small circuit on my prototype board but it does not want to work as I want it to. I am using a transistor to try to keep the...

Hi. I have an idea about making one of those travel mp3 players with loudspeakers. By loudspeakers I mean that 4 people should be able to hear the music in a crowded place. I want to use a Picaxe to control the player. I have searched a little bit on this forum and on a lot of threads people...

Hi. I was wondering if someone knew a minature GSM and GPS modules? One minature GPS module is for an example this one: http://www.4dsystems.com.au/prod.php?id=106 But it is harder to find a GSM module that is minature. The dimensions I am looking for is something like 25mm width, XXmm...

Hi. I was wondering if someone knew if it is easy to make a small device that emits some radio waves constantly and to use another device to track the signal. Needs to have a range of about 20 meters and to have an accuracy of about one meter or so. Meaning that there should be a detectable...

Hi. Does someone know of a way to detect when a servo is stuck? Let's say you send the servo from 0° to 180° but something blocks its path on the way, could be anywhere from 10° to 170°. Is there some way to detect that it is blocked and stop it from breaking? I was thinking maybe by detecting...

Hi. Is there any way to know how long time it takes a picaxe to execute a specific amount of code? For an example a 40x2 running a code with 500 if statements. Each if statement checking if a variable matches the number of the if statement. As a worst case cenario the variable would be 499 so...

Hi. I am trying to make a 08M controlling another one. I put together a breadboard and have two 08Ms and some diodes. I want 08Ma to blink the LEDs on its pins and then serout a command to 08Mb to make it blink some LEDs on its pins. Here is the code so far. Master: main: b1 = 1 pause...

Hihi. I was wondering about those LED cubes I have been seeing on the internet. Most of them control each "floor" of LEDs and not each individual LED. When you have 3x3x3 it's 27 LEDs making it nice for the 40x2 but when you go to 4x4x4 or 5x5x5 I guess you have to figure out another way. I...

Hei. I wanted to ask if it would be wise to short the outputs that I am not using. For an example. If I take a 08M and only use one output and one input. Instead of pulling the unused pins high or low can't I just short them, to destroy them, and then I don't need the pull up/down resistors...

Hi. I have a project I want to build. It's in two parts and the first part is the SIM card. I want to be able to receive an SMS with a "password". If the "password" is correct then send an sms back. The password part is not important right now as I think it's only code based. I have a cheap...

Hi. I am working on a little project. I want to be able to shoot IR light from a IR emiter and catch it with an IR sensor. I bought both IR emiter and the sensor from http://www.techsupplies.co.uk/PICAXE . Here is a simple block diagram. The IR emiter shoots the IR light forward and if a...
