DIY Phone - Incoming/Outgoing Call & SMS Using GSM Module & Arduino

We present you the Simple Homemade Phone using GSM Module and Arduino. This simple phone is capable of calling to another number as well as receiving an incoming call. Similarly, it can also be used to send an SMS as well as read a received SMS. So we have interfaced GSM Module SIM800/SIM900 with Arduino UNO Board. A 16x2 LCD is used for displaying the operations that are happening like displaying signal strength, carrier name, incoming or outgoing call, SMS sent received status and also time elapsed. The 4x4 Keypad is used to enter the number or type an SMS text using the alphanumeric keyboard. The mic is used to transmit the spoken sound and a speaker is used for ringing and listening incoming voice. This simple homemade phone can be useful for final year projects and also for understanding the functioning of the GSM module using some AT Commands functions. The components can be purchased from the link given below. All the circuit diagram, connections as well as every explanation is included below.
