what is the HID device you want to get detected as??
did u load all the necessary files?
Or may be to check the communication first, you should try mounting the HID codes from microchip applications library.
Its difficult to measure using a multimeter, since transformer will be operating at very high frequency, and I'm not sure if multimeter can read at that high frequency. A better way to read will be on an oscilloscope.
For that 1800 turns you can choose the finest available copper wire, since your current will be very less. You can maybe go for 42-43 AWG. And yeah FvM's suggestion is much better
you can use a sensor network including distance sensor, IR sensors, etc to come up with a solution, otherwise you can use a kinect and develop your environment around it.
For a better performance, you can create a 3d visualisation and accordingly feed commands to the user to take directions...
Hi barry!!
sorry to misread you, I was thinking something else.
BTW for Pot based circuit, I think your device will turn up more into a device dependent voltage as well, since your device impedance will matter a lot when you are setting a voltage.
I would still go on with a buck converter...
I just read a lot of quite complex ideas. I think I can suggest a simple one. why dont you use a 16:1 mux?? you will surely need 4 control lines, but that can be on board. You just need to create some gap at the beginning and ending to signify the start and end of the reading. Apart from that...
I agree with barry!! If not a good idea to use potential divider. But I'll correct him here, this potential divider will work if your load is having low impedance than the potentiometer, otherwise most of the energy will flow through the potentiometer resistor and that would be waste of energy...
Yup it will. But it depends on coupling factor as well. Generally for current sense, primary conductor is also wound for a single turn over the coil to give a better coupling factor.
I would say you need to rethink your logic.
A few suggestions : use switch statement outside your if(count_in ==1) and use this block only to update the value of count.
you are getting an auto increment B'coz once you get into the while loop (first while after checking the button ==1), you never go back to check it again, and you are stuck in infinite loop. Count++ does its work at every cycle and you find that system is auto incrementing.
Moreover to check...
