    Detecting horizontal position

    Revisited a few details on the little ATtiny85 and it might just satisfy your requirements. Found a video(rather than explain everything here) where the bloke uses a Arduino UNO for programming. Essentially same programming arrangement for the code, just need to rename i/o's to suit the little...

    Technique Question

    Do everyone a favour and proof read your input. In reply to other query on soldering, it is essential that the soldering surface is clean and free from contaminants. For example, acid from handling. Best approach(if it is bare copper) is to clean with a scotchbrite pad or steel wool and then...

    Samsung Monitor repair

    Last pic looks pretty conclusive to me, even without any further testing. Board similar to this advertised on Ebay from the States for US$29.00. https://www.ebay.com.au/itm/Samsung-2494HM-LCD-Monitor-power-Board-model-1P-54155B/264027306199?hash=item3d7940f8d7:g:xJUAAOSwzcNb4hdW

    Detecting horizontal position

    Ah, ok.... Worked mostly with Arduino as it is relatively straightforward with heaps of contribution to go to if ever in a pickle. Also did a bit with Picaxe but it was rather limited in what it was capable of. Then there were some with 8 pin microchip pic12F683 when we were doing the ignition...

    Detecting horizontal position

    Series connection would require both to close to get a circuit. Parallel connection will give an OR contact. (one OR the other). Problem is, one cannot differentiate in logic as to which is which. Alternative is, if used as 2 inputs to a microcontroller, such as say an Arduino,then you can OR...

    Fan making humming sound but not turning - CBB61?

    Bearings tight perhaps? Not much torque in these motors.

    Samsung Monitor repair

    This should never be done. Some of the voltages should not be present unless the power button is operated. What indication do you get there? Should be some LED indicator somewhere, possibly dual colour.

    Frustrated

    Just stick to the link I gave you for Talking Electronics as it will give you animated examples in some cases. Forget these other foreign videos. They'll more often than not get you in a tangle. While you are at it, another word of warning. Don't take too much from Instructables as being...

    Need inductive loop/clamp for A0 input to measure -30 to 80 amps dc

    Detecting horizontal position

    I'd get the module, remove the sensor and install remotely with wiring back to the module. Sensitivity is a module adjustment and even at that, limited to whatever Arduino considers as a high or a low. You may find the mounting to actually be less than directly upright. Also be aware it has a...

    Samsung Monitor repair

    It may be that all the monitor would need to be connected to get the power supply running but I don't see why it would need to be connected to the PC. Monitors usually have a menu screen which would be sufficient to tell if operational. Advice already given there.....point is, you may...

    Current sensing using transformer - how to limit inrush and false sense

    Simplest non-invasive method would be to use a programmable timer set to the maximum run time of the device. Start the timer which allows the device to start, and after the above run time setting, power drops to both the above device and an auxiliary no voltage contact relay. No_volt relay...
