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
