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...

Yeah I am pretty sure it is "standard". I got a backpack on it. Here is a picture: And here is some Arduino code that I have used to successfully display text on it using Arduino Uno. In my picaxe code I have tried to change the address to 0x27 but it gives me an error. "Error: Please use...

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...

Yes I connected pin 14 (pin 8 in my case since I am using 08M) to ground. I made a simpler version while I was waiting for answers from forum members. It looks like this: It has the same problem. Just starts without pressing the button. Might it be because when the picaxe starts up, all...

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...
