GSM module Interfacing with PIC Microcontroller - Make and Receive Calls EMBEDDED By Aswinth Raj   Aug 23, 2017 26 GSM Interfacing with PIC Microcontroller PIC16F877A - Make and Receive Calls GSM modules  are fascinating to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a normal microphone and speaker to this module and converse on your mobile calls. This will open doors to lot of creative projects if it could be interfaced with a Microcontroller. Hence in this tutorial we will learn how we can  Interface the GSM module (SIM900A) with our PIC microcontroller  and will demonstrate it by making and receiving call using GSM Module.  We have previously interfaced it with Arduino and Raspberry Pi for calling and messaging: Call and Message usin...

Interfacing Ultrasonic Sensor HC-SR04 with PIC Microcontroller EMBEDDED By Aswinth Raj   Sep 26, 2017 12 Interfacing Ultrasonic Sensor HC-SR04 with PIC Microcontroller For any project to come alive, we need to use sensors. Sensors acts as the eyes and ears for all embedded application, it helps the digital Microcontroller to understand what is actually happening in this real Analog world. In this tutorial we will be learning how to  Interface Ultrasonic Sensor HC-SR04 with PIC microcontroller . The  HC-SR04 is an ultrasonic sensor  which can be used to measure distance anywhere between 2cm to 450cm (theoretically). This sensor has proved itself worthy by fitting into many projects which involves obstacles detection, distance measuring, environment mapping etc. At the end of this article you will learn how this sensor works and how to interface it with PIC16F877A microcontroller to  measure the distance and display it on the LCD screen ...
