About this project

Hey all!

How's you doing?

You all have vehicles in your home. Vehicle safety is important to all.

I am back with a similar type of project.

In this project I made a bike unlock alert system using a GSM module and Arduino.

When the bike is unlocked, it sends a text message to the phone number that is uploaded in the code.

If any intruder or thief steals your bike and unlocks it, it directly sends alert message to your phone.

Steps to build this project.

1. Gather all components like Arduino Uno, GSM Module, M - F Jumper wires, sim module, 2 DC jack of 12V.

2. First connect Arduino cable and upload the code without connecting Tx and Rx pins.

3. Connect jumper wires to GSM Module.

4. Insert Sim to GSM Module and Connect Rx pin to Arduino 3, Tx to Arduino 2, Vcc to +5v and GND to GND.

5. Now press the reset button of Arduino to receive message.

6. Check whether its working or not.

7. Place all the components in a secured box and connect dc jack to GSM Module and Arduino and make sure to short the RESET button of Arduino otherwise message will not sent to mobile phone.

8. P.S : Connect dc jack to correct terminals of battery

red wire to +ve

black wire to -ve

9. Here is my bike.

10. carefully check and connect with the polarity of wires.

11. Place the box carefully and check all connections.

Tighten it with zip tie so that when bike runs the box will not get loose.

12. Now take key and unlock the bike.

13. See that alert message is received.

14. Now fulfill my dream please.

Thanks!

I hope you all like this project.

If you like the project, follow me and respect it.
