Arduino GPRS tutorial

Connecting to the Internet using the GPRS service is very easy using an Arduino and a TinySine GSM shield. That opens up a whole new world of projects. Our projects can now easily sense the environment and log that data in an online database even from remote areas!

This project, connects to the Internet via the GPRS service and visits my website in order to download a small text which is then displayed on a Nokia 5110 LCD display. The text that it downloads is located at this path educ8s.tv/test.txt and it is our familiar text “It works fine!”. As you can see, after a few seconds, the text appears on the display! Great, our project works fine! We can now connect to the Internet even from remote areas given that there is GSM coverage at that area! The connection speed is slow, at most time less the 100Kbps but it is more than enough for simple projects! Let’s now see how to build this project!

The parts needed in order to build this project are these:
• An Arduino Uno
• A TinySine GSM shield
• A Nokia 5110 LCD display

WHERE TO BUY
——————–

1. Cheap Arduino Uno: https://educ8s.tv/part/ArduinoUno

2. TinySine GSM Shield: https://educ8s.tv/part/GSMShield

3. Nokia 5110 display: https://educ8s.tv/part/NOKIA5110

4. Powerbank: https://educ8s.tv/part/Powerbank

5. Small Breadboard: https://educ8s.tv/part/SmallBreadboard

6. Wires: https://educ8s.tv/part/Wires

Since some of the digital pins of the Arduino are used by the GSM shield we have to connect the Nokia LCD display to the remaining ones. The TinySine shield is using pins D2,D3,D7,D8 and D9. I am going to use pins D4, and D10 to D13 for the LCD display. Check the connection diagram and also watch the Nokia 5110 LCD display tutorial I have prepared for more details. That’s it. If we now power up the project, it will connect to the GSM network, next to the GPRS service, and after about 2 minutes it will display the text from the remote server. The procedure is slow, we are going to miss the speed the Wi-Fi.
