433MHz Radio Frequency (RF) transmitter and receiver using PIC12F1822

433MHz RF Remote control system with PIC microcontroller This project shows how to use low cost 433MHz RF transmitter/receiver modules to build a 5-channel wireless RF remote control system using 2 x PIC12F1822 microcontrollers. The used RF modules in this project are cheap and easy to use with any microcontroller. These modules are shown below with pin configuration: Communication protocol: In this 433MHz ...

PIC12F1822 + DS3231 + Remote Control

PIC12F1822 is a small microcontroller has only 8 pins which is not enough for building a real time clock using DS3231 with set buttons because the DS3231 needs 2 pins and the LCD screen needs 3 pins, therefore I've only 1 free pin. I connected that pin to an IR receiver and I used a remote control with a lot of buttons where I used only 3 buttons and the problem solved. This post shows how did I build a sim ...

Make a Wireless Thermometer with a PIC Microcontroller

ntroduction In this article, I'll show you one way to make a wireless thermometer using two PIC microcontrollers. One microcontroller, the PIC16F688, will measure voltage from an LM34, convert it to an ADC value, and transmit some data. The receiver will receive the data, and display a message on an LCD. Sending data with the 433MHz transmitter is easy: in my case, I connect the PIC TX pin to the 433MHz dat ...

Interfacing ESP8266 with PIC16F877A Microcontroller

Interfacing PIC16F877A Microcontroller with ESP8266 In this article, let us discuss how to interface WIFI module ESP8266 with a PIC microcontroller. So far you might have been using the ESP8266 module as a standalone microcontroller or might have been using it with the Arduino library. But, when it comes to hardcore embedded system projects we should know how to use it with PIC microcontrollers as well. Thi ...

IR Remote Controlled Home Automation using PIC Microcontroller

R Remote Controlled Home Automation using PIC Microcontroller In this project, we are going to use a PIC microcontroller to remotely control few AC loads by just using an IR remote. A similar project IR remote controlled Home automation has already been done with Arduino also, but here we designed it on PCB using EasyEDA’s online PCB designer and simulator, and used their PCB designing services to order the ...

How to Send E-mail using PIC Microcontroller and ESP8266

In this tutorial let us learn how to send E-mails from PIC Microcontroller using famous WiFi module the ESP8266. This tutorial uses PIC16F877A IC and MPLABX and XC8 compiler for programming. At the end of this tutorial you will be able to send E-mail from any normal E-mail ID like Gmail, yahoo etc to any other E-mail ID. Hence this tutorial assumes that you have some basic knowledge on ESP8266-01 Modules an ...

Remote Control Server

One of my friends asked me if I could design a circuit for him to be able to remotely power up a server. He has 2 servers and he didn't want to keep them both on whilst he travelled. He wanted to be able to turn on a server when he needed it. He has one server which is on all the time (web server) to which he RDPs occasionally. The project involved a microcontroller circuit with RS232 interface and a simple ...

Underground locator generator for Radiodetection using PIC16F628

Introduction I obtained an early vintage Radiodetection® RD400 "LLTS" Precision Line Trace unit for a very low price through eBay. The RD400 is the receiver portion of a transmitter/receiver pair that comprise an underground cable locator system. Because the matching transmitter was not available (hence the low price,) I had to design one that matched the two audio frequencies detected by the receiver. "LLT ...

IMAR-3 PC-KEYBOARD ADAPTER FOR SPECTRUM using pic16f84

While I was writing some tips to solve problems about Spectrum' keyboard, some guys asked me for the possibility of using a PC-keyboard coupled by adapter. One market solution was launched by 'Sintech', but isn't available the scheme nor the program used by inner microcontroler. This lack of information pushed me to do an innovating project: I would do the design, prototype, programming, debugging, etc. Thi ...
