Hello Sir,
I am currently working on a project on gps & gsm based tracking with RFID based security.
My project needs to interface 3 modules (gps, gsm & RF module) to the micro controller but the problem I am facing is that the microcontroller can be interfaced to 2 modules & I am not getting how to connect the RF module.
We are using 89c51, SIM 300.
Would be thankful if you help me with connecting the modules or any alternatives.
