Tarjeta de desarrollo para PIC16F84A

This is a new design of a tutorial board based on the popular PIC16F84A microcontroller. It features eight single leds, a 7-segment display, an LCD display and five push buttons. It is an ideal solution for the beginner to take his/her first programming steps in the world of microcontrollers. Having an in-circuit-programming (ICP) header, it can be easily reprogrammed without unplugging the microcontroller each time, provided that the programmer also supports this feature...

Reloj 12/24 hrs con PIC16F84A

This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it "The ANP LED Clock". (ANP stands for Almost No Parts.)

 Using the micro controller PIC 16F84A or the 16F628 (same pinout), this clock have more and improved features This LED clock may not be the easiest to build but surely it is the one with fewer parts that you can find, for that reason I call it "The ANP LED Clock".

Controlador de temperatura con PIC16F84A

The Temperature control module was a part of my Final year undergraduate project,which consisted of transmitting data wirelessly.
The module uses an inexpensive 8 bit Temperature Sensor the TMP37 from Analog Devices.
Since the data was analog and the PIC16f84 does not have an analog input,an external ADC had to be used.
Texas Instruments’ TLC549 was chosen for this.The advantage of this ADC was that it could communicate with the microcontroller serially.You may also use similar ADCs from Maxim-IC.
The LCD is a normal 16×2 display which uses the Hitachi Controller HD44780.
The module is breadboarded and not done on a PCB.Schematics are included in appropriate places below.
