Pic Programmer USB

Introduction: Pic Programmer USB

About: Student of Computer Science, Faculty of Sciences, National Autonomous University of Mexico, I like mechatronics and robotics and programming course, my favorite food is pizza like most, I love pizza

Well I'm bringing home pic programmer, inexpensive clone pickit2 and support products microchip pic 18F2550 is used, this controller has an output voltage of 3.3v and 5v for different pic's that use different voltages.

Well this programmer is built because here in my country Mexico, a PicKit2 costs about $ 35 and to create this programmer to spend more than $ 15.

Before continuing, I want to make a clarification: this programmer public has so far worked perfectly with different models Pics I've programmed. Either way I can not guarantee that works well in all cases and not give a full support because there are too many variables in play at the level of software and hardware and would have to spend all my free time alone to this.

Step 1: Materials

    good job mr

    what is the job of the three pin header and how to connect it with microcontroller
