I've had an idea for creating a non dcc sound modual for a model railway that could be built for under £20 While watching a youtube video of various locos doing their thing, I thought it would be interesting to take some sound clips of the locos and play them in relation to the track voltage on...

Are there any obstacles or protocols that should be used when trying to Connect multiple picaxes to each other via serin/out commands For instance if I wanted to connect ten pics together via one wire (plus common earth return) and control them from one central circuit, would this be possible if...

I've been working on a circuit to control a servo and a relay for what seems like months now and have got to the stage were the circuit and code has been refined and work 99% as I want it to When the circuit starts up for the first time c.3 is used to set the parameters of the servo movement...

I want to build around 15 small pcb circuits each with an 08m2 on board which will control an individual servo. I was thinking that it might make sense to have one power supply for all the picaxe circuits that is regulated and smoothed and another power supply feeding the servo's. The supply for...

Hello all, its been a while since I was last on here but I've returned with a query regards getting a servo to move slowly. I'm trying to get a servo arm to move slowly between two points and then back again. It works up to a point in that the servo does move slowly but not throughout the whole...

Hi all I've built two small circuits that are connected together with a ribbon cable that provided V+ and V- between both boards from the same on board power supply. On the main board the axe is a 20x2, and on the secondary board the axe is an18m2 and they are connected together again via the...

I have just discovered the hard way that the 20x2 only supports the servo function on the B ports and NOT on the C ports :eek: However this particular piece of information seems to be lacking in any of the spec sheets for the 20x2. Or its very well hidden. It is possible that I have missed the...

I'm just going to start playing around with the touch function on an 18m2 but would like some advice/clarification around the touch pad. The data sheet states that a touch pad can be created using a 20mm copper shape on a pcb as long as the pad is isolated from the finger by 2mm of plastic. So...

Hi all, Using a servo for the first time I want to make the servo travel from one side to the other very slowley using the code below... symbol delay=30 start: servo 2,150 pause 1000 for b1 = 150 to 180 servopos 2,b1 pause delay next b1 pause 1000 for b1 =180 to 150 servopos 2,b1 pause...

Hey all, Not strictly picaxe but would be an excellent project for one http://www.wimp.com/turnon/ Rgds, Sid

I'm a bit confused around the pwm and hpwm commands and the 14m. The pin out and appendix for advance use shows PWM2 on pin C5. In my simplistic way I would assume that there should be a PWM0 and a PWM1 as well but this is not shown. The data says that....... "C5 can be used with the pwmout...

Hi all, I've made a few picaxe curcuits but my knowledge of electronics is a bit sketchy and I've come up against a problem while making a new picaxe circuit that involves a diode. As you will see in the attached diagram the axe is powering led1 via a 330r resistor, however led2 which is...

I want a laser cutter but I can't afford one, not even a cheap one from China via ebay, so I looked around youtube and watched a few diy laser cutters and thought that perhaps I could make the hard ware but how do you get a 2d drawing from the pc to control the cutter. Obviously some sort of...

With much help from this forum I have just completed a Picaxe circuit that will control up to 8 signals for a model railway and in the spirit of sharing, the link to this circuit is here http://www.stuartmoore-modelrailways.co.uk/multiple_signal_control_unit.htm Doubtless some will pick holes...

I have one circuit sending data to another circuit via a serout/serin connection and both circuits work as expected. The output circuit monitors a set of 14 toggle switchs and depending which switch is used sends the data to the other circuit eg: if switch1 is high then b0=1 etc then b0 is sent...

I've made a small circuit using a 20x2 which works well enough until I switch on a couple of 240ac > 24/12vdc transformers which are close by, then circuit starts acting up. If I disconnect all wiring into the circuit so the only connection is the 5v & 0v the circuit stops playing up, but as...

I'm using a 20x2 and the pinout shows that pin 10 or C.0 is a dedicated hserout pin. I've read manual 2 pages 92 & 93 but I'm still obviously missing something because when I use the following code.. start: hsersetup B1200_8, 1 b0=1 serout c.0,n1200_8, ("uuuuuuuuuu") pause 10 serout...

hi, Advice from a previous post helped me to get an 08M to talk to a 20x2, now I'm trying to get the same 08m to talk to a 28x1. I've written a short test code which works in the simulator start: ;serin s8x1 setfreq m8 serin 2, n1200_8, ("ABC"),b0 if b0=1 then goto led1 if b0=2 then goto led2...

I've written a program that starts off by waiting for a serin input, when this is received the program happily goes off and does the other things required of it. However at various points within that program I want to "gosub" back to the serin section of code to see if a new piece of data has...

Hi all, I've spent the last two evenings trying to get an 08 to talk to a 20x2 via a serial out/in link but without success. I've managed to get the 08 to talk to another 08 but when the transmitting 08 is connected to the reciving 20 nothing happens, so I assume that error is in the coding of...
