What is Arduino?
Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
Build "sketches" (combo of C/C++) in a Java based IDE and uploaded to Arduino via serial port.
/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
This example code is in the public domain.
*/
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
What is firmata?
Firmata is a generic protocol for communicating with microcontrollers from software on a host computer. It is intended to work with any host computer software package.
This firmata protocol uses the MIDI message format, but does not use the whole protocol.
-
Port of pyFirmata. No longer active.
-
A full IDE aimed at replacing the Arduino IDE.
-
Requires custom sketch. Implement own command wrappers.
-
Not fully implemented or currently active.
