Hello my name is John and im fifteen years old. In my school i must do a project for arduino but i am having difficutlies in programming it. The project is a security system with a monitor sensor, 2 aleph magnetic contacts and a 4x3 keypad. I know how the arduino works(just the basics). Basically, when the sensor detect movement or the contacts are activated i want an alarm to start. Also i want to activate and deactive the system using a code with the keypad. Im just a beginer with coding and i cant find anything on google so i found this forum and i hope it is still active. Also i would like to clear out that i would really appreciate any kind of help not just telling me what to do(which is also fine in the worst senario) . Thanks for your time
This forum is certainly active, but very people are prepared to invest time in order to help create custom code, which is made even harder since they do not have the parts to test. Start with the basics:
- What is the input / output for each device you want to connect?
- How does each device get power (what are the voltage and current requirements)
- How would you connect each device to the Arduino?
- Start with one device at a time and write basic code to interface with it (see if there is any existing code online).
- Integrate the code.
Ok i will take your advice and start working piece by piece. But i can be sure that im going to have troubles with the keypad as i am not familiar with it at all. Anyway thanks for replying.
There is actually quite a bit of sample code for Arduino explaining how to use a matrix keypad - an online search should give many results.
