Hello friends! I am in the final stage of my project. I am stuck with a problem.
Here are the components i have
- Mega 2560
- Ethernet shield
- SIM900A shield
SIM900A requires 12V 1A power supply.
I have mounted all these. I have used a 12V 1A external power supply. When i connect all these 3 together the voltage regulator(AMS117) in Mega gets extremely hot and i am scared whether it might burn away! Please help me with what should i do now as soon as possible!!!
