Sir i have 9 V power supply with a current rating of 0.4 A. i tried to split the supply, one at atmega arduino with 9 V, and the other was 5 V which i regulated to supply GSM module. But it didn't work, the GSM module did not turn on. can you help me hoe can i troubleshoot this matter tnx?. smiley

how did you split the power supply ? try using lm7805 voltage regulator to get a 5v for your atmega mcu

do you have a breakout board for your sim900 or how are you going to use it in your circuit ?

I've done connecting the gsm sim900d to my arduino and it works fine i can send & receive message. Now what I am trying to do is I will light up a led with a text message is there any code for that?



hi what code did u use for sending and recieving message... i am doing a project that can send and received text messages but the recieving text messages is not consistent on reading the recieve message... what might be the solution forthat

If you find a way to light LEDs with sms messages, let me know.  :)
