7 Segment Display Interfacing with PIC Microcontroller

7 Segment Display Interfacing with PIC Microcontroller EMBEDDED 12 7 Segment Display Interfacing with PIC Microcontroller This is our 8th tutorial of  Learning PIC microcontrollers using MPLAB and XC8 . We have come up all the way from  installing MPLABX  to using a LCD with PIC MCU. If you are new here, then look at previous tutorials where you can  learn timers ,  blinking LED ,  interfacing LCD  etc.. You can find all our  PIC Tutorials here . In our last tutorial we saw how we can generate  Custom characters with our 16*2 LCD display , now let us equip our self with another type of display module called the  7-segment display and interface it with PIC Microcontroller . Although  16x2 LCD  is much more comfortable than 7-segment display but there are few scenarios where a 7-segment display would come in handier than a LCD display. LCD suffers from the drawback of having low character size and will be overkill for your project if you are just planning to di

CONTROL DE ACCESO CON CLAVE ALFANUMERICA Conmutadores de corriente alterna a 220V. Presentar un interruptor inalámbrico de 4 vías. Ver un caso práctico, de cómo conmutar varios dispositivos de 220V. MATERIAL REQUERIDO.    Arduino UNO o equivalente . Teclado matricial 4×4 Un display  LCD, de 16×2  o  LCD 20×4 , I2C. Resistencias  de: 1 x 100 Ohm, 1/4W  para el buzzer 2 x 330 Ohm, 1/4W para los LEDs Un  LED rojo y otro Verde . Una  Protoboard  . Algunos cables de protoboard, preferiblemente  Dupont macho/hembra . Fuente de alimentación externa 5V  Buzzer pasivo SIMULANDO UN ACCESO CON CLAVE AUN LOCAL No es raro que de una forma u otra acabemos encontrandonos con la necesidad de montar un sistema de control que nos permita activar algo, una cerradura por ejemplo, mediante un codigo numerico tecleado en un keypad a modo de clave de control de acceso. Y como estoy seguro de que esto es algo que se nos a ocurrido a muchos, pero rara v

Digital Thermometer using LM35 and PIC Microcontroller EMBEDDED By Pankaj Khatri   May 14, 2018 4 Digital Thermometer using LM35 and PIC microcontroller In this tutorial, we are making a  Digital Thermometer using PIC microcontroller and LM35 Temperature Sensor . In this project, we will sense the temperature using LM35 and display it on  16x2 LCD . LM35 Temperature Sensor is accurate and cheaper and doesn’t require any external calibration. The output voltage is proportional to Celsius temperature scale and changes by 10mV per °C. Material Required PicKit 3 LM35 Temperature Sensor 16*2 LCD PIC16F877A IC 40 - Pin IC holder Perf board 20 MHz Crystal OSC Female and Male Bergstick pins 33pf Capacitor - 2Nos, 100uf and 10uf cap. 680 ohm, 220 ohm, 10K and 560ohm Resistor Potentiometer 10k LED of any color 1 Soldering kit IC 7805 12V Adapter Connecting wires Breadboard LM35 Temperature Sensor: LM35 temperature sensor  has zero offset volt
