so I guess I should go over the design. Basically I am using a surface mount 28x2 (I will be converting to PIC to bring down manufacturing costs). The picaxe communicates to a ws2803 chip which is an 18 channel PWM driver which drives the leds under the touch screen and the two 12v LED strips...

Hey guys, some of you might remember a while back the endless questions I had on topics such as RGB leds, serial communication, frequency adjustment, circuit designs etc... I would like to officially present to you the result of all that hard work! https://www.youtube.com/watch?v=CapW1XaoJUU...

Hi, I ordered several 28x2 chips (AFTER already running into this problem with the 20x2!) It says here http://www.picaxe.com/BASIC-Commands/Analogue-InputOutput/touch/ that the TOUCH command applies to the 28x2 AND it says on the 28x2 shop page...

Hi, I have an adxl345 accelerometer breakout board from sparkfun. I have it working with my 14m2 chip. Here is my code: setfreq m32 HI2CSETUP I2CMASTER, 0xA6, i2cfast_32, i2cbyte HI2COUT 0x31,(0x01) 'Put the ADXL345 into +/- 4G range HI2COUT 0x2D,(0x08) 'Put the ADXL345 into Measurement Mode...

Hello. I am making a circuit that uses the famous MSGEQ7 audio spectrum analyzer IC feeding values into a picaxe to make some visualization effects. I have a pre-amp microphone circuit set up as well as a stereo 3.5mm audio jack (however I have connected the L and R pins to make it "mono"...

Hi. For a picaxe project I am working on, I have a rectified 60hz 120v DC that has NOT been filtered by a capacitor (so it is purely a rectified sine wave) . I now need this to be converted back to a ~120v ac sinewave. The only way I can think of doing this is to make an h-bridge out of mosfets...

Hi, I am using 3 common anode 12v rgb led strips. I have been successful in pwming them for different colors using an npn transistor. I have each of their red, green, and blue pins connected together so each of the 3 strips are essentially connected together and doing the same thing. But now, I...

Hi all. I am working on an RGB led project and I am trying to get a picaxe talking to a WS2803 chip. I know on this forum there is a lot of information and code for the WS2801 chip, but I haven't had any success learning or transferring any of that knowledge to this. I am very new at...

Hi guys. I am having trouble understanding how to impliment a mosfet and transistor in the way that I need, and am hoping someone could help me out with this really simple problem. I havent taken any pictures of an actual circuit yet because this is a "How am I supposed to make this circuit"...

Hi, Guys I am having more problems with this hook that squeezes the lever of a gas pump as you may have seen in previous posts. Basically an h-bridge is used with a picaxe to raise or lower the hook based on a touch sensative button. The hook is raised or lowered by a dc motor. Everything was...

Hi, All I need to do is control the direction that a DC motor is spinning. Every time I hook it up, there is ZERO response from the motor and the darlington transistors heat up to the point of smoking. I have checked my wiring a million times but no luck. See the attached pictures...

Hi guys, I am running into a problem which I'm sure is very easy to solve. I am just blanking out at the moment. some probably unimportant details about my project: I have a project which raises or lowers a hook (responsible for opening or closing a lever) by use of gears and a motor. There is...

controlling several leds with 1 picaxe Hi. I am looking to find the best solution to control 5 rgb leds with 1 picaxe. I know that ways to do this have been discussed many times, I am not asking for ways to do this! I am asking the experts here for their advice on the BEST way to do this. I am...

Hello all. I am working on a project that is battery powered. I want this project to be completely waterproof, so I need all the user interface buttons to be touch sensors. This is all fine when it comes to the normal operation buttons, however when it comes to the power on/off button it is a...

I have asked alot about this, I know. But I still need help with this chip and getting it to read the values for each electrode to b0-b11. I have done all the research I can. I have looked all over the datasheet, I have read the only 2 threads on here about the mpr121...

Hello, I am trying to get the MPR121 breakout board from sparkfun to talk correctly to the picaxe. The MPR121 chip has 12 touch sensitive electrodes. All I want to do is read the values for each of them. here is the datasheet of the chip...

Hi, I looked at basic commands for math and I didn't see the answer. I am getting a value from 0-70 in b3 and I need b10 to be a value from 0-255 where the closer b3 gets to 70, the more it affects b10 (so on a graph it would be a curve rather than a line.) So I want to do b10 = b3^1.3042 how...

Hello, I bought the breakboard for the ADXL345 from sparkfun and can't seem to get it to talk to the picaxe. I have gotten it to work perfectly on the arduino, so I know that the chip itself is working. The problem I am having is that the values I am receiving from the chip are all 255. The...

Hey guys, I have a 14m2 picaxe. I need it to be smaller to fit in a certain space and I dont have time to order an 08m2 picaxe. I only need 1 i/o pin from the chip. If I were to literally cut the picaxe in half leaving the +,- serial in,serial out, b.0,b.1,c.4 and c.5 pins would it still...

Hey guys, I ask a lot of questions, but never share anything. So I thought i'de just share this code. I was looking for code for an rgb led color fading, but couldnt find anything. I even posted a thread about it. I ended up just writing it myself, so heres what I came up with. It's nothing...
