Halloween Hack: How to automatically activate your Halloween Arduino Project

Halloween Hack: How to automatically activate your Halloween Arduino Project

With Halloween coming around the corner it is time to see how we can automate some scary projects. We are going to explore two of my favourite ways to do this. First we are going to look how to integrate a pressure plate switch (a big push button you step on which we are going to build), then we will look at how to connect a motion sensor (Passive Infrared Sensor or PIR) to your scaretastick project for the maximum scare factor. I recommend you also watch the video below to get the most out of this tutorial.

Helpful Tip: How to create a more professional and user friendly Arduino project by storing your configuration in the EEPROM

As makers we strive to make projects that are easy to use and have a more professional feel about them. If your project is user configurable (e.g. are you using C or F for your temperature), how do you store that information so it is kept, even when the Arduino gets reset?

 What if you could make your Arduino remember these types of user changeable settings (e.g. using a menu saving your Wi-Fi password)?

Tutorial: Using Interrupts to improve the functionality of your Arduino projects

A couple of weeks back I wrote a short tutorial on using timers instead of delay() functions to make your Arduino projects more responsive to input from buttons and sensors. Using interrupts is a different way to achieve the same result. By attaching an interrupt to a digital pin the Arduino will halt what it is doing to handle the input as it happens making your project more responsive. 

EXPLAINING WHAT AN INTERRUPT IS AND DOES.

Let’s say you are listening to your music with your noise canceling headphones on. At that point somebody calls you on your cell phone. Of course you don’t hear your phone ring as your music is loud and you are distracted by it. Luckily there is someone in the room with you who hears the ringing. This person pokes you in the side to let you know that your phone is ringing and tells you can answer it.
