Sensor "persistence"?

[iahim67]

I think the RESET could be the problem but I cannot find the schematics of this Arduino Mini to determine the precise source of the problem.
I'll use the Nano or the Pro in the future ... but thanks anyway, it was instructive!

Have you tried just supplying it with 5V, without the reset attached?

[iahim67]

Yes, I did, no change.
I have removed the capacitor on the RESET pin and I have pressed the RESET button on the Mini, nothing happens to my surprise.
I shall try to use a different 5V power supply instead of supplying the Mini from the USB adapter. Eventually remove every wire between the Mini and the USB adapter and use an external 5V supply.

I have re-wired everything and it works now if I remove the wire from the USB Adapter "EXT. RESET" signal to the 100nF capacitor connected to the Arduino RESET pin - after the code upload.
I guess we can say "solved", I still can use the Arduino Mini if I remove either the RESET capacitor or the wire to this capacitor, like in the attached picture ... nice help on this forum anyway:-)

@iahim67

thanks for the feedback, and good that you got it working finally :)

One more thing :simple_smile: , this is the Arduino Mini schematics if someone needs it (not very easy to find):
