"You are going to design an alarm system that works by pushing a button to arm it. The alarm will have a motion detector that alerts when someone is moving. When the motion is detected, a 60-second countdown timer begins (visual). The 60-second counter can be interrupted by inputting the proper code. If the code reaches zero, a buzzer will sound. Upon the buzzer sounding, a message should be sent to the Arduino display that reads “The authorities have been notified. Please exit the premises.” "
I really have no idea what to do. If anyone knows what I should do, I would appreciate it very much.
Hello,
at first make selection for the hardware that is suitable for yout project.
The second step is to take a pencil and a piece of paper and draw a flow chart for your sketch.
In third step you can check the examples inside the IDE for the basic function are needed.
Let´s start!
Look. What you are asking for is a ton of work and you'll have to make a lot of research. This forum is designed to ask for help when you don't understand a problem or when you need advice but definitely not for asking someone to make your project. I suppose you understand what I mean, right? There are tons of tutorials and projects you can find here on Arduino Project Hub, Instructables, YouTube etc. look into basic arduino tutorials first and also about pir sensors. Good luck.
Why is this urgent? any school would give you pleanty of time to design, build, program and test your project. When was this assengment issued? What have you written so far?
What is your exposure to software and hardware so far ?
Show us what you have done so far.
In the Arduino IDE, use CtrlT or CMDT to format your code then copy the complete sketch. Use the </> icon from the ‘reply menu’ to attach the copied sketch.
Show us a good schematic of your circuit. Show us a good image of your ‘actual’ wiring. Give links to components.
If your instructor hasn’t taught you anything about hardware or software, invite them to come here so we can have a chat.
Well you forgot to answer the question about when you first got this assignment. And you haven't told us what components you have to work with. And you haven't said what your coding experience is and if you have made any attempt to write any code.
So can we help with some code for an unknown collection of components to implement a fairly complex and poorly defined requirement that apparently you've not bothered thinking about until it was too late even for experienced programmers to complete? No, not a chance.
Here is some hints. Look into how to use a 16 x 2 LCD and a 4x4 keypad just a quick google search will do it! and then look into how to use the HC-SR04 Sensor and then start makeing the code... if you go into TINKERCAD.com and go to circuits there is examples on how to do it. just google this thing
The place I would start is to clearly define all the system requirement. Then I would draw a flow chart showing all the actions decision points etc.
Is this a hardware / software project or only a software project.
If indeed it is due next week I suggest you go out, have a beer and enjoy yourself as I don't see how you can do this is a week if you have no clue where to start.
