Re: Several questions and problems

I think I've found the source of the problem is to kill the store ... RGB LEDs I have are of common anode, common cathode instead of ... tube so much trouble to make them work but I did not realize it ... and so the dough I have in the circuit should actually be food, so I have to buy RGB LEDs commo...

Re: Several questions and problems

Is that I have reviewed everything, but I did not do some simple programming. I mounted on a breadboard only PIC with tension, with a 10k resistor to pin 1 Vdd, and a cable to give finishing touches to the Vdd pin to pin 10 player who came out for the pin voltage output signal to the LEDs that not b...

Re: Several questions and problems

When I test the sensor on the breadboard, the output voltage and draws me when I approached the magnet goes to 0, which gives me a 1 or a 0 logical. In contrast, taking the montage just like on the plate, the sensor did not change from 0 to 1 and always gets me is near the magnet 4.95V or not. The m...

Re: Several questions and problems

Hi After reviewing the track well, the only problem I found is that hall sensor had fueled by MCLR pin 1 has a resistance of 10Kohm to Vcc, which reduced me to 2.2vy is 5v power sent him to the hall sensor. Now I get the 5v to the sensor. Even so, the circuit is not writing anything ... - I get the ...

Re: Several questions and problems

I bought another power supply rated at 2A, so that will feed the engine with the 1A and 2A Circuit with. Then I put a screen on the outcome of the PICkit 2 programming, which I think is going well, so I doubt arise because I do not write the PIC. http://img685.imageshack.us/img685/1971/pickit2.th.png

Re: Several questions and problems

Hi Brad, I built the one chip pov, but I finish work correctly, so I'll make a couple of questions about the problems I have come to have if you can tell me more or less to be if you know. First say that I followed the steps in your explanation instructables. - First I welded RGB LEDs with their res...

Re: Several questions and problems

Once I had all the material I assembled it all, the perfect wheel plate, the tension reaches all parts well, but I have emerged a couple of problems. The first is that the RGB LEDs that I have do not work or I get the feeling they do not work as they should then seek information on their operation, ...

Re: Several questions and problems

Hi. The Hall effect sensor component which I choose not as I found Hall effect latch, switch, sensor, and most for SMD with 3 legs, and with prices ranging from pennies to $ 10. If you could show me a link to the component that you used some might find one with similar characteristics, because this ...

Re: Several questions and problems

The information I received from your instructables project, in that there is no problem as I see that everything is well explained step by step. What I mentioned is that the circuit is very small, but the plate on which is mounted, the horizontal, is very large. And I wondered if it was some mechani...

Re: Several questions and problems

Brad has convinced me, I dropped the schema and is far simpler than the 8x85, but before you start purchasing components and the montage, I would like to know: - What is it and for serving the "Hall effect sensor ", but if it enters the MCLR must be a pulse generator or something? or is it to send t...

Re: Several questions and problems

Hello, I commented on but only you know, since I have seen the explanation of 8x85 in various forums and websites, to find out about these by offering a bad circuit, when theoretically would copy it, program it and then we each would work to gauge the speed sampling and rotation, nothing more, and a...

Re: Several questions and problems

Hello again, After watching and reviewing over and over again the circuit, I have concluded that the circuit provided is the same as shown in the photos of Dai Omie, and I've noticed that the layout provided is the same the photography circuit where the problem lies in the output of the LED latch th...

Re: Several questions and problems

OK, I did not put the sensor, thinking that without him and start to show something, so that when you deploy the sensor gives the signal through RA5, should provide the impetus to start writing. I'll try this week. The engine is 5,000 rpm, if theoretically to see the POV must go to 25Hz, 25Hz X60s =...

Several questions and problems

Hello, Almost a year ago to look to this project, and gradually I've been doing with my free time I have as a hobby, and I find several problems have if I can lend a hand. I have the assembly like you have your timber and the motor attached, I have made with the circuit board that is on the web, I h...

I mean the PIC16F628A is programmed with the .hex of the MPLAB, and EEPROM27C512 is programmed with the .hex to obtain with Excel and HxD, program for paint, I am right?
