Here we call one of the effects in setup() instead of in loop() - this way it doesn't keep repeating itself. The function "buttonTriggered" will reset the Arduino, which then will run setup() again and show the effect. Once setup() is completed, it will go to loop() and do noth...
This is because of the help of the Arduino Microcontroller itself and the If-Else function of the Arduino programming language and also the Pulse Width Modulation. The microcontroller has two sensors attached and able to get its average to display it in the serial port of the Arduino Program ...
If you are using a different Arduino or Arduino compatible device, you will need to change this function. If you are using a FIO or LillyPad Arduino or Arduino Pro Mini 3V or Arduino SimpleSnap or other Arduino that has ATmega168 or ATmega328 with 8MHz oscillator, change the line TCCR2B...
In the Arduino, the sine function is namedsin(). It takes a floating-point value (known as a "float") as an input and returns a float as an output. Unlike integers (whole numbers), which you use for most things, floating-point values give you the ability to use decimal points (such...
