RFID – is also an option for sensing interaction/motion!
RFID is used to wirelessly identify something. RFID is about reading tags that have a small amount of information stored in them. They are super cheap and tags such as UHF RFID can be read from far away. Passive UHF allows objects to be read across the room, and battery-assisted-passive and active tags can be read across buildings!
RFID will be important for the future of IOT(Internet of Things) systems. In the future every object may have a digital identity that rests in an ecosystem of identifiable objects by means of a prevalent network and mode of information exchange! how will this change the way we interact with the world??
Arduino does not just come in one form. There are several you can choose on depending on what you want!
Here’s a few I’ve used:
~also there’s ‘off-brand’ Arduinos that are cheaper but of course are riskier in terms of quality. I bought the Elegoo version of the Arduino Mega off of Amazon for about half the price and it’s working just fine for me!
A stepper motor is a very magical motor. That is because it works through electromagnetism. The shaft of the motor is mounted with a series of copper coils and magnets. The copper coils are charged by an electric current in a sequence in order to activate and deactivate the magnets. These forces of attraction and repulsion work to spin the motor!
Arduino is great for controlling stepper motors! You can control speed of rotation extremely accurately in the code and with sensors!
So now’s the time for starting some real interactivity with lights and sensors! Again my goal is to create sculptures with embedded lights and sensors that react according to the environment.
there’s a lot of cool sensors out there!
For a simple example of an idea I have is to build a box (either with a material that is illuminated or has holes in it) then program LED lights to interact with a sound sensor, put it all in side and wallah! I think a lot of bands would like this for some good ambient set design!
Something else I am working on involving lights and a motion sensor, so using the same design idea as above, I could have a box that gets brighter or changes color the closer someone walks to it.
