I have tried these and they don't work very well at all, mercury works better, what tilt switches don't seem to like is very slow change of angle, they don't operate well if used very slowly. I have look at all sorts of tilt sensing.

I was wondering which way to go, i'll try and get one of them and see if they work better, at this point of the project its a case of working out which direction is best, the mercury tilt switch does work, but there is must be a better way to sense small changes of tilt and act on it?

Hello I tried putting too much info into my opening lines, i am trying to move away from a mercury switch if possible and use other methods of getting angle detection, the mercury switch at best is 15 degree's and that varies on every switch, looking for something more repeatable at a lesser angle.

Following on from my question ref can a certain pib be used for ADC input, the question was leading to this. I have bought a SCA60C module online its based on a chip by VTI N1000060, it has a LM393 to give 2x switched output that i was hoping to use in the first instance, but it seems they are...

Thank you for the replies from all the picaxe gods on here, its an existing project I wanted to adapt, being a pcb it's much harder to rearrange uses of pins, will play on a blank 08m2 and reconfigure when looking at another run of pcbs, Thank you all again for your answers and creative thinking.

Hello All, looking at altering an existing project that uses a 08m2, currently actual pin4 or C3 is and can only be an input i understand, what i want to do requires it to have ADC function, i seem to remember some pins can be made to do functions that they normally can't do, is there anyway to...

Yes my mistake i have corrected it now. The code works very well but at the moment the catcher doesn't catch the pendulum as i have to sort the code for that to happen, Jack tells me when the clock stops in the code it restarts at the correct time, which is great, we don't have much code space...

This is the current schematic for the setup, also included is the pcb design

So after about a year of playing about with the idea, Jack Burns has been helping me with the coding, no not quite like that until now is has done everything needed to get the code to work along the lines of Hippy's finite machine setup, we have had to go from a 4 bit screen to a 8 bit screen...

Having been forced into the 40X2 I have spare pins, didn't really see any point having the screen showing when not required. I do have a menu button already of which its first task can be to switch power on via an output and as you say rum the setup routine, good point that it needs doing I had...

Starting at building a PCB for the project, how best to turn the oled screen off when not needed? A n-type mosfet controlling negative to the screen maybe? Disable the E input? what's best for power saving, other than setup there will be nobody to see the screen 99% of its life

Interesting i use the PC817 which i find great, another old component, really need to upgrade to something more current and smd but its not broke so why change

Ok thanks, so it looks like normal speed is 8Mhz and max speed without resonator is 16Mhz, and it will only use the external resonator if i use commands to tell it to, so my conclusion is to fit a 8Mhz resonator giving me access to a speed of 32Mhz by command should i need it later in my project.

What I find misleading then is than the development board seems to have a 8mhz resonator fitted and by the terminal setup is running on the internal resonator at 8mhz, so it seems you can have an external resonator fitted and not actually use it, or my clock speed would be 32mhz which it isn't?

Thank you everybody just so kind of you all

The idea of moving over to the 40X2 is one thing, trying to buy one seems almost impossible to use on my AXE development board? Anyone know how currently has stock of them? Maybe somebody has a spare one i can buy from them?

I see on the AXE091 development board the resonator that is used is a 8Mhz, what does everybody use for a 40X2, does it matter what the resonator is within the 4Mhz to 16Mhz range? I thought we set the running frequency in the code, i see the picaxe store sells a 16mhz resonator along with other...

Hello again, possibly silly question I'm working on a pcb for the project and running out of pins so looking to go to the 40X2 so i have pins spare. Main question being on the OLED there are connections for RS and E can i use any outputs for these or does the pins i use have to have certain...

Papaof2 Thank you for the reply, i removed the 2 loads that the 3 relays control, so just the relays connected and it ran fine, i re-connected the electromagnet and still ran fine, so re-connected the actuator and had problems, so seemed it was the actuator motor that caused so many problems, so...

Jack Yes like you say 5v would be forced into the picaxe pin. i can add diodes inline with the picaxe pin to prevent 5v entering the picaxe pins I have just removed the loads that are switched and the code runs fine so seems to point to back emf issues from the electromagnet and possibly the...
