In this small project I will show you how to use a TC35 GSM module properly and how to use it with an Arduino Uno to send a SMS with it.

Step 1: Watch the Video!

This video gives you all the information you need, so you will not destroy the TC35 while you use. I will give you some additional tips in the next steps.

Step 2: Get Your TC35 GSM Module!

Step 3: Download the Schematic and Sketch!

Make sure to get the connections between the Arduino and module right by using my schematic. And don't forget to upload the code/sketch to the Arduino

Step 4: AT Commands?!

Here is the site where you can find all the AT commands for the module:


And also a manual for the board:


Step 5: Success!

Now you should be capable of sending SMS with your Arduino.
