Introduction: Sensor + Arduino +gsm Shield
this is my first time to upload experiment
simply it is about a sensor ( any type of digital sensor) once its sense the arduino will send a SMS to you with a text
Step 1: What Will You Need ?
you will need:
1_arduino uno or duemilanove (any type could be)
2_ GSM Shield with SIM card
3_a digital sensor ( I used Normaly close switch as a sensor)
***since I used a normally close switch that will effect on the software I wrote it
Step 2: Fix a GSM Shield on the Arduino
put the GSMShield on the arduino that you will use it
and the connect your sensor
the +wire with 5V ,-wire with GND and the signal wire with pin number 8 ( you can use any one from 4 to6 and from 8 to 12) code
Step 3: Code
follow the code and enjoy
We have a be nice policy.
Please be positive and constructive.
