    Driving a Mosfet (Wat am I doing wrong????)

    Hi Guys, can someone help me please. Im trying to get a Picaxe 18A to trigger a Mosfet N - Channel (BUK456). But im only getting like 3v on the output, why? Heres how i hooked it up. Drain - To 12V Siren Source - (+)12v Gate - Picaxe output 5v (no resistor) I also have a resistor on the Gate...

    Hows Project going now of yours Haxby?

    What, it did'nt work. I tried replying to Haxby's old thread but interestingly enough it doesn't transfer it over to the new Forum, Huh? Bugger it, Haxby I am just interested in how you are getting on with that project with your Ultrasonic Reversing Alarm as I am doing the same thing at the...

    Have you seen the thread I am looking for?

    I can't find the bloody thing! I while back someone on here was asking questions about Ultrasonic sensors and the Ultrasonic module. I need to get back on to this parking radar project and wanted to know more info about it as far as using external sensors off the board (The board being the...

    Is this actually possible to do??????

    Yep, me again. Still playing around with code and want to be able to the following. Input 1 can be my trigger which is a switch going low when pressed. Output 2 can be my output which simply turns on an led. Now the tricky part. If Input 1 goes low once (a single negative pulse) than I want...

    Playing with code

    Ok, I am just mucking around with code at the moment and have now got stuck again. How do I make this led turn off? I know if I put 'low 3' it will stop but I don't want to do that. Can someone please modify this code so I can see how you do it. Thanks guys symbol ledstop = input2 start: if...

    Stop Flashing you stupid led!!!!!!!!!

    Hey guys, can someone help out with this problem please. PICAXE 18A. I am using a transistor (npn) on the output of picaxe to trigger an input of same picaxe. When this input is grounded the picaxe will flash a light on a different output twice and than stop. The problem is IT WON'T STOP...

    Turbo Timer Issues

    Ok I was going to design a little Picaxe circuit to go with my new Turbo Timer but the Turbo Timer has an issue. When I turn off car the turbo timer starts counting down but the engine cuts out immediately(Picaxe circuit not connected at all yet). I have heard this is something to do with the...

    Siren Driving with positive outout

    Hi Guys Hi need to get a Picaxe to drive a siren with a positive output. It must put (+) positive to the siren to drive it. I don't want it to gnd the siren through a transistor as I need the sirens earth to be permanently grounded for this application. It's just a normal 12v oscillating car...

    Part 1 finished. How to do Part 2?

    Ok I have done part 1 with the Ultrasonics Project. So far I have the following code which I am using from the SRF004 DATASHEET. symbol trig = 3 ‘ Define output pin for Trigger pulse symbol echo = 6 ‘ Define input pin for Echo pulse symbol range =...

    2 Completely Different Questions

    Hi Guys. My first question is: I want to make an ultrasonic reversing thing for my car. I just want the display to be a BAR of leds and a Piezo. Can someone lead me to a starting point with this project. I want to build it with a Picaxe of course. My Second Question: Does anyone know where I...

    OH NO!, I think it's dead

    I have a Picaxe circuit I have designed for a car again. It was working very intermittently and starnge. Only difference this time is for example instead of triggering INPUT 1 to ground through a npn transistor, this time I just put pin 1 directly to ground through a 1n4004 diode. I don't think...

    TEZARM explains better (I Hope)

    OK. Lets see if I can describe it better. If I permanently put input 2 to ground then ouput 5 goes high for 2 seconds then STAYS OFF. (if input2=0) If I take input2 away from ground then output 5 will AGAIN go high for 2 seconds then STAY OFF. (if input2=1) If i put input 6 to ground then...

    It won't work

    This Code does not work, WHY? It says mistake in this line: symbol on=0 And the same problem with: symbol off=1 start: symbol on=0 symbol off=1 if input2=on then ONE if input2=off then TWO if input6=on then THREE ONE: high 5 pause 800 low 5 goto start TWO: high 5 pause 2000 low 5 goto...

    3 PHASE

    Hi Guys. Look, I know this is completely nothing to do with Picaxes but does anyone know where I can find some diagrams on how to hook up 3 phase mains voltage. I need to wire up my hoist into a new building and have googled around but not found anything useful at all. Need info concentrating on...

    Help, I am absolutely confused with code!!!

    main: loop: if input2 is on then loop high 5 pause 800 low 5 loop2: if input2 is off then loop2 high 5 pause 2000 low 5 goto main OK.The problem I am having is finding where to put this piece of code into the above so it works. go: if input6 is on then go '(goes to gnd) high 4 pause 2000...

    OK. The Problem is.........A PROBLEM.........

    OK. Here is my next question. How do I Program a Picaxe 18A so that when it gets a constant positive trigger it tells an output to turn on for 2 seconds and then off again. Now the Problem is that the Picaxe is to IGNORE all Positive Feeds to the Input Pin between 0 Seconds and 2 Seconds. Only...

    Is it OK

    Hope this is not to stupid a question but... Is it ok to have a Input Pin triggered negatively or positively, obviously having the pull up and pull down resitors on the input aswell. I am guessing the answer is yes as you can change it in the software. But I want to send A Positive 12v Trigger...

    How on earth do you do it ???????????

    Someone please help me. Heres an example. Picaxe 18a. Ok Pin 1 is the TURN ON trigger (A N/O Switch going to ground when closed). Pin 2 is the TURN OFF trigger (Also a different N/O Switch going to ground when closed). Pin 3 is my output with my led which is a loop so it flashes. OK. So when...

    Am I the only one that kind of feels Guilty?

    Ha Ha Ha. Ok I have to comment on this. Am I the only one that feels guilty about posting in a topic I need to know the answer to but it's not exactly Picaxe related. I know that you guys would always have the answer to all electronic questions Picaxe related and Non Picaxe related. People seem...
