ArduinoBuy Download Getting Started Learning Reference Hardware FAQLearningsearchBlog » Forum » Playground »Examples Foundations Hacking LinksExamples Digital I/OBlinkIn most programming languages, the first program you write prints "hello world" to the screen. Since an Arduino boarddoesn't have a screen, we blink an LED instead.The boards are designed to make it easy to blink an LED using digital pin 13. Some (like the Diecimila and LilyPad) have theLED built-in to the board. On most others (like the Mini and BT), there is a 1 KB resistor on the pin, allowing you to connectan LED directly. (To connect an LED to another digital pin, you should use an external resistor.)LEDs have polarity, which means they will only light up if you orient the legs properly. The long leg is typically positive, andshould connect to pin 13. The short leg connects to GND; the bulb of the LED will also typically have a flat edge on this side.If the LED doesn't light up, trying reversing the legs (you won't hurt the LED if you plug it in backwards for a short period oftime).CircuitCodeThe example code is very simple, credits are to be found in the comments./******Blinking LED-----------turns on and off a light emitting diode(LED) connected to a digitalpin, in intervals of 2 seconds.

ArduinosearchBuy Download Getting Started Learning Reference Hardware FAQLearningBlog » Forum » Playground »Examples Foundations Hacking LinksExamples Digital I/OBlink Without DelaySometimes you need to blink an LED (or some other time sensitive function) at the same time as something else (likewatching for a button press). That means you can't use delay(), or you'd stop everything else the program while the LEDblinked. Here's some code that demonstrates how to blink the LED without using delay(). It keeps track of the last time itturned the LED on or off. Then, each time through loop() it checks if a sufficient interval has passed - if it has, it turns theLED off if it was on and vice-versa.Codeint ledPin 13;int value LOW;long previousMillis 0;long interval 1000;void setup(){pinMode(ledPin, OUTPUT);}////////LED connected to digital pin 13previous value of the LEDwill store last time LED was updatedinterval at which to blink (milliseconds)// sets the digital pin as outputvoid loop(){// here is where you'd put code that needs to be running all the time.//////ifcheck to see if it's time to blink the LED; that is, is the differencebetween the current time and last time we blinked the LED bigger thanthe interval at which we want to blink the LED.(millis() - previousMillis interval) {previousMillis millis();// remember the last time we blinked the LED// if theif (valuevalue elsevalue LED is off turn it on and vice-versa.

ArduinosearchBuy Download Getting Started Learning Reference Hardware FAQLearningBlog » Forum » Playground »Examples Foundations Hacking LinksExamples Digital I/OButtonThe pushbutton is a component that connects two points in a circuit when you press it. The example turns on an LED whenyou press the button.We connect three wires to the Arduino board. The first goes from one leg of the pushbutton through a pull-up resistor (here2.2 KOhms) to the 5 volt supply. The second goes from the corresponding leg of the pushbutton to ground. The thirdconnects to a digital i/o pin (here pin 7) which reads the button's state.When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin isconnected to 5 volts (through the pull-up resistor) and we read a HIGH. When the button is closed (pressed), it makes aconnection between its two legs, connecting the pin to gr

arduino’s analog pin 4 (SDA). And the pin labelled as SCL on the MPU 6050 to the arduino’s analog pin 5 (SCL). And that’s it, you have finished wiring up the Arduino MPU 6050. Step 2: Uploading the code and testing the Arduino MPU 6050 To test the Arduino MPU 6050, first download the arduino library for MPU 6050, developed by Jeff Rowberg.
3. Then, use the Arduino IDE to write code to send to Arduino. Once a code is sent to the Arduino, it lives on the Arduino Uno. Any future edits to that code on the computer will not be sent to the Arduino unless it is manually uploaded to the Arduino Uno. When using the Arduino

2.2.2 Arduino IDE Download and install Arduino IDE from the official web-site of Arduino. Get a version 1.6.4 or newer. It is important that the Arduino IDE version that you get has the additional boards manager. We used Arduino 1.6.6 during the preparation of this document. If you want to have the exact same behavior as us, use Arduino 1.6.6.
