Why are there two PWM pins in sim900a?
The PWM is mostly in microcontrollers for industrial applications but due to IoT, the module offers two PWM pins which helps to make the IoT and PWM based device without using any third interface. The audio interface will help to connect the mic and speaker with SIM900A.
What is the RESET pin on the sim900a?
The device has an external LOW input signal reset pin to reset the device with the use of an external signal. To extend the range of the SIM900A the antenna pin needs to connect with an external wire. The official antenna is also available for the module. The module SIM900A has multiple types of power pin.
How to interfacing GSM module with AVR microcontroller?
Connect to GPRS with your APN and Pass key. Can be obtained from Network Provider. Here we will use AT +CMGF and AT+CMGS command to send messages. If you have used GSM module with Arduino, while receiving messages you can use +CMT: command to view the mobile number and text message on serial monitor.
How to send DTMF number with AVR microcontroller?
