hello guys... please I need an assistance.. am new to programming and I have an arduino uno board. I have problems with interfacing the board with GSM (sim900a) module which I wanted to use in controlling lighting I also don't know how to go about the coding. the GSM module has 2 sets of pins (6 pins in a group 3vt 3vr 5vt 5vr and 2-gnd) also ( tx rx and gnd as another set)

You can connect arduino with GSM module using Rx,Tx pin and look for AT commands to interact with the GSM module from Arduino. As this require serial port for communication you might look for SoftwareSerial if u are using Arduino UNO/mini.
