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.
advantages over incandescent light sources = lower energy consumption, longer lifetime, smaller size, and faster switching, variety of color and controlling capabilities!
RGB LED = LED containing one red, one green and one blue LED
PWM = post width modulation is a technique used (in/with Arduino) for controlling the brightness of the LEDs, allows you to fade the LEDs, Arduino only has 6 pWN pins so you can only hook up 2 rgb LEDs at a time =[
-also PWM is what is called with AnalogueWrite() commands
-also PWM is used for driving a motor at various speeds
Of all the technology trends that are taking place right now, perhaps the biggest one is the Internet of Things; it’s the one that’s going to give us the most disruption as well as the most opportunity over the next five years.
A micro-controller is a computer! That is, it is a chip with a CPU (central processing unit), that has inputs, outputs and memory (RAM).
Micro-controllers are “special purpose computers.” They are made to primarily run just one program and perform one task (while the computer you and I are on is made to run thousands of programs). Because of this they are generally quite small and low power and low cost.
Micro-controllers are often embedded inside another device, often a consumer product. For example, a microwave has a micro-controller inside of it that takes input from the keypad and displays an output on the display and then runs a program that turns the power generator on and off.
