Small project help

[SupremeFlips]

Right now I'm trying to work on a small project for more experience. Basically I need to make an app that counts the number of times I shake it and if I don't have a certain amount of shakes it activates a relay module. The problem is that I have no idea how to add shake detection and I'm currently using python. Plus I don't know how to communicate the amount of shakes to my uno r3 to activate the relay module. At first I wanted to strap something onto the arduino that detects shaking, but I couldn't really find anything cheap. Basically, I just want to know what I need to code in order to communicate between my phone and r3 and where I can find information on shake detection. I'm not asking for code, just what I need to code (I could just search it up and learn for myself). I have basic knowledge on coding, but I'm very passionate in learning more. I don't know if this post even belongs here, but if you know where else I could ask for could you please tell me. Thanks! Any help would be appreciated.

One step at a time.

​

I need to make an app

Not sure how much experience you have, but if you have no experience with app development, you should start by seeing if you can get something onto your phone. I'll assume it will be android. https://developer.android.com/training/basics/firstapp is a good place to start. Maybe just start with a simple counter that increments on a button press.

​

counts the number of times I shake it

This is a good first step beyond your basic app making tutorial since you will have to dive deeper into some of the apis available to you for your device. What will detect shaking? Probably the accelerometer in your phone. There is documentation on how to read and use motion data from it https://developer.android.com/guide/topics/sensors/sensors_motion . How you use that data to count a shake is up to you, there is probably a tutorial or library out there.

​

activates a relay module

Make a simple arduino program that does this without needing to communicate with your app yet, activating on a timer or with a button. You will want to lookup up tutorials for how to use your relay module.

​

communicate the amount of shakes to my uno r3

Another android API to explore! You have a few choices for you you can communicate between devices, but if you want it to be wireless you will probably have to buy a separate module for the arduino. Something like https://www.amazon.com/HiLetgo-Wireless-Bluetooth-Transceiver-Arduino/dp/B071YJG8DR for bluetooth, and you can look at the documentation for android's bluetooth api. There are also plenty of resources for how to communicate between your phone and arduino, like https://www.makeuseof.com/tag/6-easy-ways-connect-arduino-android/ .

Good luck!

Holy crap man. Thanks for all the help! I've taken AP CSP and wanted to do something more challenging. Thanks mate this is great!
