The Purpose of This library is to use the module in the most easy way and transparent.
##To download and Install. Go to Releases click the " Source Code (zip) " button, then rename the uncompressed folder to Sim800l. Check that the Sim800l folder contains Sim800l.cpp and Sim800l.h
Go to arduino IDE Sketch >> Import Library >> add library... Select the folder Sim800l
OR
Place the Sim800l library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE.
| Arduino Uno | Sim800l | Notes |
|---|---|---|
| +5v | (3.8v)~(4.4v)! | Power supply input |
| 10 RX_PIN | TX | |
| 11 TX_PIN | RX | |
| 2 RESET_PIN | RST | Reset Pin |
| GND | GND |
You can regulate the voltage to the desired with this, is not the best, but for start it's easy.
For the reset pin they need NPN transistor, this is an example circuit that you can use.
