Many Thanks, same results have to admit there are quite a few things on my breadboard so i will start again from scratch. Thank you

I am trying to reaquaint myself with picaxe after several years of non use. Useing a Picaxe 18m2 I am trying to read a POT (on a breadboard) it is simply wired to the same 5v supply with the "wiper" connected to c.0 the resulting debug output is just a series of random numbers main: readadc...

Dear Oracacle Thank you so much. I will have a go with this over the week end. I know that the motor I am playing with is not powerful enough but once I have proved that the electronics work I will roughly measure the torque required and get a bigger one. The torque required for microstepping...

Thanks so much for your reply. For the moment I would just input the numbers as part of the program i.e. if each tooth requires 245 steps for a particular gear, then that is all the program will do so for a different gear with more or less teeth I would change the number of pulses in the...

Hi its been a long time since I've been on this forum. I have a little project in my head to control a Dividing Head or rotary table on my milling machine with a stepper motor. (specifically to make clock gears). the only info I can find is related to Arduino. I have managed in the past to...

referred to as "smart wire" in the manual. has anyone found a way of attaching this to a small component. I want to make a proportional air valve using a tyre valve as the basis. Solder doesnt work, brazing's too hot. was wondering if anyone knew of a neat and compact way to do this. The only...

can anyone tell me why this doesnt work main: readtemp C.2,b27 ; read value into b27 serout b.6,n2400,(254,128,#b27,"C") if b27<20 then heat ; turn on heat source if b27 >23 then heatoff 'turn off heat heat: high c.1 high c.6 gosub main1 heatoff: low c.1 low c.6 gosub main1 when this...

My incubator project requires a geared motor to turn the eggs! This comes from an old electric pepper mill not a terribly powerful motor but very low geared running from 12v. this was all working well until a couple of days ago when I had a software problem that caused the motor to overrun and...

Just a quickie In a program I am writing I have four similar lines "if b8 ="1" and b9 = "5" then gosub ..... 3 similar lines follow question is how do i activate them so to speak in the simulator many thanks

I'm guessing this is a silly question! cos its probably been covered many times but I cant find it on the forum! Have built a strip board circuit with an LCD and a ds1307 timer, all up and running works a treat but when I disconnect the download cable and try to run it alone it doesn't run...

I dont know if this is simple or stupid. Is it possible to run a motor so that it hits a physical stop and then switch off the power having monitored the current. I assume there is a build up when the motor is put under a load! I dont know what this might be called so not much Idea where to look...

Part of my incubator project. I'm getting ambitious now! Have just bought the above DS1307 to provide timing for turning the eggs every few hours, and to switch this part of the process off after a number of days. All is controlled by an 18m2 on one board simply outputting high or low to various...

Hi all I have been messing about with one of these for a while with an 18x chip using: Main: readtemp 0 , w1 sertxd ("the temp is:" #w1,13,10) pause 1000 goto main this has been displaying the temperature in centgrade of anything i put in front of it from my thumb to (near) my soldering...

Can any one point me in the direction of a project that will do this, the joystick control must be smooth, not one axis at a time. I have looked at the project files but someone may remember a project that covers this under a different heading! best wishes doggington

I have just aquired a rise and recline chair from the scrap heap. control box knackered. Have built a new one using a picax 18x chip and a uln2803 which controls 4 relays. 2single pole that control the power and 2 double pole to give me foreward and reverse. the control pad is wired to simply...

Sometime back I bought a USB to serial cable (usb010) to help me program a basic stamp(sorry to swear) I have now gone back to a couple of picaxe projects. Trying to program them via this cable connected to the serial download cable gets (error on COM 3). should I be using the axe027 cable or...

I Have been useing a short little program to count pulses, and useing the serial terminal to see that it is working properly. No problem. As soon as I disconnect the program cable it doesn't work???. I have taken out the sertxd lines ( in the code) and stopped the serial terminal opening after...

I am useing this little program to count a flashing IR LED counter: count 1,1000, w1 sertxd ( "the value of w1 is" , #w1,13,10) ' displays value on screen pause 100 goto counter the LED is flashing via a 555 timer at 148 flashes per sec this works nicely but what I want to achieve is to...

Firstly many thanks for the replies to my previous questions. I am experimenting with the picaxe18x with an infrared reciever and a stepper motor for no other reason than curiosity. A short little program runs the stepper forewards and reverse through the Darlington 2803. The motor is running...

I am trying to get a display in the serial terminal window to read 3 pots. by useing the code :- Sertxd (''The Value of b2 is'' , //b2 , 13 ,10) ( my hash sybol on this keyboard doesnt work) By useing the above I get a scrolling display of the the text and value , I would like to keep...
