* - Arduino Wiring - POT DISABLED IN SOFTWARE AFTER 15 MAY 2016 -

Pin 8 will provide the crank or primary wheel signal - essential
Pin 9 will provide the cam or secondary wheel signal - optional
Pin GND

15 May 2016 - Fixed several bugs. 1 RPM defaulted to zero, 2, on exit it would default to POT …
…mode which can cause the rpm signal to go way out of range (disabled POT mode), 3. added state tracking for RPM variable as an experiment (druid4arduino 1.3.0 or higher)

Supposedly RPM pot is commented out in Arduino IDE, but can be returned by removing the comment code.

UPDATE : NEW VERSION - 2.2.0 tested working

4 December 2017 ·
New code pushed out (tagged v1.0_SerialUI-2.x). NOTE: This requires SerialUI 2.x to compile, Tested with the 2.1.6 tag from git. Tested and verified working with devicedruid (successor to druid4arduino) and a serial console application (minicom on linux), though any serial comm app should work at 9600-8-N-1 with Echo On. All patterns appear to work and sweep as well as linear mode seem to be working normally. Please let me know of any bugs you find with as much detail as possible.

I'm getting closer to publishing my simulator interpretation (hopeful, wishful thinking on my part considering things), so I will follow your guides in order to bring up the Mini's I have for running Ardu-stim.

Thank you for your guidance.

I stuffed up.

Adru-stim can output 2 triggers, pin 8 for crank, and pin 9 for cam, and I only put pin 8 crank trigger in my simulator circuit. Doh

Plenty of time to recover.

Well that was a write-off. Ardu-stim with UNO works fine on the bench, plugged it into my SIM board and the LEDs go out. Plugged in extra power pak to the UNO and smelt smoke. Quickly unpluged it and the diode? on the power plug side next to the 2 big caps got hot. Luckily it still works.

That's not good.

Any idea what happened?

Not really - I'm not a EE so I'm not good at that -, but it looks like a high current drain, like a short, because the LEDs go dim before going off.

Even though Druid4Arduino has rpm, there is a pot controlled rpm pin connected to the UNO, that I can't remember where I got from, that might have something to do with it.

The on-board oscillator works on a scope, the UNO works on a scope, but The UNO on the SIM board it dies - on-board osc not connected -.

The other bad news is that 2 people have their SingleSided working - I guess the circuit is ok -, but mine is also dead in the water.

Peculiar, at least.

I know it's of little consolation but if people are using your designs with no ill effect, that means your design is good... right?

Maybe take a step back, put on some George Thorogood (one bourbon one scotch and one beer perhaps?) or Grateful Dead... then go back over things with a clear head.

One thing that caught me out when i was playing with Ardu-stim was setting the specifics for sweep RPM. You enter it as its written, min,max,rpm/sec.

So if you want to start at 1000 rpm, sweep to 6000 rpm and have it go up in 500 rpm increments, its 1000,6000,500

I had some trouble where it doesnt sweep cleanly at low rpm, but it gave enough of a test that i could still work with it, it was just a tad jumpy.

[DanSankey]

A0 is the wiper input for the RPM, also i didn't use the serial UI, i don't even know what it is if i'm honest.
