hi zmanultra, i think u ought to search this site throughly, as there are more than enough discussions, articles and tips for one to become an expert from a novice. i learnt a lot from this place and i think i owe a lot to elektroda. Take a look at the search engine and u may find ur project done long ago here.... Goto davi
traxonja a few years ago i programmed a project in PIC assembler which was storing data from a magnetic card reader in a 24C16 using a 16F84. I have posted the source here: hope this is useful for you best regards
Hi there Guys and gals :) I have a problem here - I'm trying to set up a little project for my kids, and I'm a bit new to this, so naturally I'm having a bit of difficulty. I need to use a pic16f84a with a number keypad to light up numbers on a seven-segment display. The pin diagram for the keypad is: Here--->
Hi, if you need a good project try here:
this is our project design the main problem with the hardware is the software... we don't have a software yet... please kindly help me with it... we are using PASM program. thanks
hi friends, could you please send me some examples based on PIC 16F72.or some projects related to this so that i can practice it.even a small led based project will do. will be really thankfull. eagerly waiting for your response thanking you
thanks, but i still have one more question : i want to start any project using pic16f84a, i have some projects for the 16f84 (without A) . can the 16f84a work with the same code ? Regards,

is brend in world of microcontrollers. So I believe they never be publish something which is not good. So, try to make more effort to find mistake in your circuit. This programmer is good covered I think. Any programmer project will not work if you enable to find mistakes.
I have tried hard that project w/o positive results. Here's the schematic (attached) for the AN828 H ehe he hee h he ! There is the problem in your schematics. XTAL has got 3 pins and you mustn't connect the center pin with GND ! Good luck for U !
Use a 10K resistor between MCLR & 5V add a 0.1uf cap across the power & gnd pins on the PIC Check my download section for a pdf file called Inchworm Quick project , it has the schematic and source for blinking an LED on a 16F84A
Hi! has some SMS projects with english description
I am looking for a programmable chip to drive an array of leds: 1. chip should be able to control up to 16 leds or more. probably 0603's 2. chip needs to be very low power. (battery operated) 3. I would like to control intputs to make leds have different patterns 4. A nice function of this chip would be to have a fade effect for led array.
Here is a project I am working on. I can give you the schematic and HEX file, for code I can help you to write your own :wink:
we're doing a project on 16f84a that needs to count pulses... any ideas how to do it?
Hi, im doing a project about pressure sensor but i havent find and get any schematic for the i planning to use this project and change it question is: 1.

Greetings guys. I am currently working on a project using the PIC where I am programming a PIC and interfacing it with a 16x2 HD44100H LCD, programming in assembler. I have used one of the bits on PORT A as an input bit. Each time the input bit is low it triggers the PIC to display a message on the LCD. There's a counter which counts how many times

masters.. I am also intersted in this project.. sir hameed, can you share this circuit with us? ??? ??? ??? please.... here it is pure sine wave inverter using 8051, just u need is Proteus V7.5
You have to include the library in your project. There is a panel with the libraries those can included in your project, you have to select the "USRAT" library.
you gonna b kidding me.... u are going to do a project and don't know what to do????? My suggestions are: design and code; in parallel. Means design a small part, test it and so on, then integrate ur design and recheck i. What about C?? Do u have any knowledge???
hello, I recently started learning microcontrollers and ran into a little problem here okay, so once I got all my stuff delivered I rushed into building that power circuit thing to transform 9v to 5 (from tutorial for noobs Beginning Embedded Electronics - 1 - SparkFun Electronics ) -6 hours of my life
