    Button to button circuit

    Why would blowing the horn while the headlight is on stall the bike? Btw, what's a Pit Bike? Chris

    Serial communication problem.

    The Great Cow Basic Forum will guide you through transitioning. They will never talk down to you and are happy to see Picaxe users join the GCB fan club. Sometimes I think that forum never sleeps because replies are fast! There are also gobs of GCB vids on youtube. You will find that the syntax...

    Serial communication problem.

    That comment was an expression of how much I love GREAT COW BASIC! Perhaps I should have said "Wean" you off Picaxe? Don't get me wrong. I admire what the folks at Picaxe created. They created a painless and inexpensive gateway into embedded programming. If it were not for Picaxe this old...

    Reed switch door alarm help

    Here's a complete schematic. The component ID numbers won't match yours but the values should be correct. To save a bit of power I placed the exit delay LED in series with Q1's base. I also increased some R values from what you had to save some more battery life. I kept your RC time constant...

    For this discussion: Exit 555 = U1 Entrance 555 = U2 When I drew that circuit I assumed that U1 & U2 share the same Battery. IE: Vcc (9V rail) and GND (0V rail). I suspect that you neglected to disconnect U2's Reset pin from the 9V rail. This must be done before tying the 2N2222's (Q1)...

    Uses of USB IC Programmer

    I could be wrong but judging by the image you posted it looks like the K150 PIC Programmer. The K150 has been produced in quite a few incarnations. That's the first one I've seen enclosed. They're usually sold in open board form. The K150 was never intended to be an IC tester. It's function is...

    Something like this. The resistor values are not critical. Chris

    Use the button triggered 555' output to hold the reset pin low on the reed switch 555. You'll need an NPN transistor to invert the logic to the reset pin though. Chris

    Serial communication problem.

    I haven't installed the latest version of GCB yet but I doubt that the terminal looks any different than my version. Here's a screenshot of a macro I wrote that sends that string every 100mS. I'm reading the Input buffer because I'm using a Loop-back Tester. So anything I transmit echos back to...

    Serial communication problem.

    Constantine, I don't know if the serial terminal included in GREAT COW BASIC provides a 'Send until the earth stops rotating' option but it's built into the IDE and the software is free. Best of all GCB will nurse you off Picaxe. ;) Chris

    PIR operated DC motor project odd behaviour help

    That is contrary to what you posted earlier. If the base -emitter junction never goes to 0V then it's not logical that the vibrator output does. What does the vibrator output measure when not ringing? Yes, a resistor would be better. Better yet,.. do you have a Red LED? If so connect the LED in...

    PIR operated DC motor project odd behaviour help

    A thought..... Have you ever measured the vibrator output voltage with the vibrator motor disconnected? I'm taking an educated guess that you'll find it doesn't drop to 0.0V when not loaded. If so connect the vibrator motor and test the timer again. Chris

    Is there a logical answer to my question? Chris

    PIR operated DC motor project odd behaviour help

    Despite the fact that using all black wires is bad practice (the source of many "Oh sh!t" moments) I don't see anything wrong there. Admittedly, my old eyes suck! Measure the voltage between the base and emitter while it's ringing. It should swing from near 0.0V to ~ .65V upon each ring. Chris

    PIR operated DC motor project odd behaviour help

    No surprises there, so something else is amiss. Logically it would point to the 2N2222 basing. Please post a clear photo of the GSM - 2N2222 - Timer interface. BTW, why are you testing this with the timer's timeout set to only 2 seconds? I would think that the GSM's vibrator output has a pulse...

    You forgot #(5). It's important! Also, is it timing out as it should? Chris

    Serial communication problem.

    General purpose serial terminals don't typically provide a function like that. What's the purpose of repeatedly transmitting the identical message? Chris

    PIR operated DC motor project odd behaviour help

    That's higher than I'd expect. I would think it would be closer to 0.30V because the LED in the Opto doesn't pull much current. That said that voltage is close enough to GND to turn the Opto LED on. So that's not the problem. The voltage between the Collector and Emitter should inversely...
