Hello, I was wondering what the impedance of a Picaxe pin would be, when using the ADC? I searched around but couldn't find any previous posts.

Hello, I am doing a school project with the Picaxe, using the 14M2. I am using most of the pins, and I need to control an LED with C.5 (serial in). The pin is input-only, how can I turn the LED on and off? The LED to connected to V+ through a resistor and the cathode is on the Picaxe pin.

And it does work. :)

About three weeks ago I designed a PCB and had it made through Seeedstudio. I recently received them and they are just fine. :o The circuit is quite small and just consists of IC socket, the download circuit, 2.1mm DC jack and pin headers. The minimum order quantity was 10 and I got them cheaply...

I recently received three 16X2 LCD displays I bought off of eBay. I would like to use them with the Picaxe and I was wondering if there was a guide for using it or bit banging it. (I will control it directly rather than use an AXE133). I have read several tutorials but they are all ATMega and...

I got the idea of making a synthesizer with the Picaxe. I googled around and it seems to have been done already though I have not found a finished project. I was thinking of using a 14M2, using the four PWM pins to have four oscillators. The plan was to use potentiometers to adjust both the...

Hello, I have known about this bug/weirdness for some time but now I am posting to see if this is a known problem. :o When using PWM in simulation with the 14M2 selected, the PWM icon does not appear on the left side pins (C.0 and C.2). Here is a picture, the program has been looping so PWM is...

The hole is not visible because it is filled with some old solder: Looks like some kind of prison shiv or something! ;)

A couple of weeks ago I tried etching some boards using the toner transfer method. Transfering toner went okay and etching went fine. I waited for about a week before soldering and I think this might have made the copper corode, parts of the traces had a bluish tint when viewed under a light at...

Hello, I am playing around with Diptrace and I'm looking for a 2.1mm DC socket in the program. I have Myc's and wa55's libraries installed. I cannot seem to find it. :) Did I miss it or can I download it somewhere?

Yesterday I recieved a couple of shift registers, the 74HC595N type. I've looked around for how to use them with the Picaxe and it seems that X2 parts have the command "shiftout" which does it all for you. Some alternative code is given here in Example 2. I have not yet tested the code. Could...

I soldered this thing together a couple of days ago. It has got decoupling caps. I hope they are they right kind. A big one for power fluctuations and a small one for higher frequency noise. It has a red LED on the serial out so it is visible when the chips are communicating with the computer...

I was thinking of what to add to the protoboard, if I decide to make a new one. I would like a status LED that would light up when programming through the USB cable, and jumpers that would decide which chip to program, since there will be room for 2 of them. I have tried with both serial in, and...

Sorry for making a new thread but I am about to order some stuff from techsupplies. What size plug will fit in this socket? http://www.techsupplies.co.uk/epages/Store.sf/en_GB/?ObjectPath=/Shops/Store.TechSupplies/Products/CON010

I got the 8x8 LED matrix soldered together a while ago but I did not properly plan the control board for it so I've had to breadbord it as much as possible. I have written a program where a single LED lights up, and goes in a circle around the edge of the 8x8. This animation alone takes up 2028...
