Sometimes you want everything in the program to stop while a given condition is true. You can do this using a while loop. This example shows how to use a while loop to calibrate the value of an analog sensor. In the main loop, the sketch below reads the value of a photoresistor on analog pin 0 and […]

This example demonstrates string-based communication from the Arduino board to the computer using a call-and-response (handshaking) method. The sketch sends an ASCII string on startup and repeats that until it gets a serial response from the computer. Then it sends three sensor values as ASCII-encoded numbers, separated by commas and terminated by a linefeed and

This example demonstrates one techinque for calibrating sensor input. The Arduino takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the

Since getting an Arduino starter kit I was wondering what to make of all those fancy buttons, shiny LEDs, touchscreen LCD displays… I was thinking about weather station, but I was told that in the maker’s world, weather station is like a “Hello World” app. Like playing “Stairway to Heaven” in a guitar store. Then, when

Breadboards are very handy, but sometimes I just want to connect one IC or some LEDs and resistors to the controller. My simple solution was to canibalize a cheap Breadboard to get two expandable PrototypingShields with some additional features. What I used: Breadboard (~3$) 2 Pieces of Veroboard (<1$) 28 PinHeader (<1$) 28 femaleConnectors (<1$)

When you are tinkering around with your Arduino and a breadboard you might want to make yourself an “Arduino Bracket”. Nothing more than header pins and a piece of wire, the “Arduino Bracket” keeps wiring neat and tidy, and lets you easily disconnect your Arduino for use in other projects. Step 1: Gather Necessary Supplies

In this instructable, I’m going to show you how to make a simple circuit/code with an arduino, which will make an LED connected to it flash from off to on, with 1-second intervals, as shown below. This is a very easy, basic idea, however it leads to many more complicated codes and circuits. Attaching the

This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishingserial communication between your Arduino and your computer over USB. Additionally, when the input is HIGH, the onboard LED attached to pin 13 will turn on; when LOW, the LED will turn off. Circuit image developed using Fritzing. For more

The ‘Poduino Case’. A protective case for your Arduino (with breadboard work area): I just received my Arduino Duemilanove and breadboard today. After some careful thought, I realized there is no way this thing could possibly survive daily life on my desk. I saw some great Instructables on plastic cases, and even one that used
