Hi, can any one help me to get the best simulation software for AC & DC, more specifically of Analog DC. I had tried lot of free, which has limitation either in the number of parts in a schematic or does not have the large list of components or it dos not give a real simulation like glowing the...
I am using a two line 16 character display LCD , JHD, in my project, I am not able to get the display clearly I have given a 5v to the Back light with 470Ohms resistor.
pls help
I need the LED to glow when the voltage drops below 11 volt (ie.zener 10 + base current of 1 volt), by reversing the zener the LED glows at 12+ volt and is off, it it is below 11 volt.
Sorry i had used a 220ohms at the ground connection of LED. i am uploading the image file to show the schematic.
When the Voltage is below 10V the Zener would not conduct and the BC557 PNP transistor should conduct and the LED should be in ON state, if the voltage is above 10V the Zener would...
I intend to use BC557 (PNP) transistor in indicator circuit, +at pin 1 (E), connect a + pin of LED at pin3(C), and the -pin of LED to Ground, the LED is not glowing (6V input), when positive volt is given through pin2 (B) the LED is glowing, since the transistor is PNP type if the base is biased...
the web site is not opening, i intend to store the phone number in PIC memory and call it to interface and generate DTMF tone and pass it through the phone line.
Tested the TIP 127 front view pin 1 base pin 2 - collector pin 3- emitter, input volt 12v 1 amp. Base 12v .8 amp, Collector - 0v. when base pin is activated, the collector output is 12v and .07 amp.
Re: JDM Programmer
Thank you for input, which is the best Programmer available in the market to handle PIC 12C...., 16F..., 18F..., Eprome 2cC....and AT...series and ATMEL 89c... etc
Re: JDM Programmer
However I was able to write, Reade and erase pic 16F84 in the same JDM, does 16F873A require a different voltage? pls clarify. Could you pls give the web site link for Pickit2?
Re: JDM Programmer
Before writting it is 10V during writting processes it is 4v. yest it is powered from the port itself. do i requirer to raise the volt though the WINPIC software?
