    Met

    Okay so I have been working on a digital metronome project using the Pic16f877a. Its nearly complete. I am looking for some help with the timing. I have had success using a lookup table for each BPM but I'm looking for something a little less bulky. The time between clicks is as follows...

    Voltage divider in a filter?

    What I mean is set the date on your computer ahead by say 10 years, install, and then put your computers date back. When you open the program it thinks you have like 2000 days left on your trial. The only catch with the trial is you cannot print directly from the program but that is it.

    iPhone Controlled Circuit Switching

    Could you provide a link to exactly what you mean? I haven't found anything too simple or inexpensive. I did find a basic Bluetooth module via spark fun for $15.00 and that's about it. I plan on using this in my home with Wifi so I am thinking that might be a better route. Bluetooth isn't...

    Voltage divider in a filter?

    If you want a great simulation program check out national instruments Multisim. It has so many interactive tools it's mind blowing. Also its component database is massive. It also allows you to perform complex calculations. Highly recommend it. Multisim 12.0 is the newest one and it isn't free...

    how to read signal from hall effect and magnetic speed sensor on PIC

    In my opinion I think the choice of the mosfet for the hall effect sensor is a good one. When the Hall Effect sensors senses that magnet it will trigger the gate of that MOSFET connecting +5V to the input of the PIC. Of course I thought that the Hall Effect is wired at 12V so when it is...

    Choosing of Micro Controller

    HI, I am a Senior at a great tech school doing a two year degree. As seniors we have to each do our own senior project of varying complexity. Most of the people in my program opted to use the Ardunio Uno which I myself purchased. Our Professor actually pushes them on most of us. The great part...

    iPhone Controlled Circuit Switching

    I am looking to use my iPhone to give wireless control to something as simple as a single pole single switch, etc. I'm not so interested in the iPhone portion of it (the software - coding) but more of the method of communication between it and a device. Also any recommendations of what would be...
