This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

allowing the sensor to measure the distance and subsequently prompt the buzzer to emit the right note. Since the project uses pretty basic components, the Arduino code is equally basic ...

On the software end, the Arduino code is pretty ... tripwire alarm project works much like those in movies. There's a tripwire — made up of a laser directed at a light sensor — that's placed ...

Here is the test code that indicates the soil wet/dry conditions using just two LEDs (green & red). int GLED= 13; // Wet Indicator at Digital PIN D13 int RLED= 12; // Dry Indicator at Digital PIN D12 ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds ... You can use only the leds if you want, the lcd is optional. The Arduino sketch code is pretty simple ...

the sensor was soldered to an Arduino ProtoShield on the pins. The other end of the 9DOF was glued to the shield. The source code for the project is based on the AeroQuad [open source quadcopter].

The readability of your code can make the difference between your project being a joy to work ... It’s designed primarily for the Arduino IDE but doesn’t have any dependencies on the API ...

Put Arduino to work protecting your secrets. This project is a keypad-controlled lock that will allow the user to select a six-digit secret code and lock out anyone without it. Now we're having fun.
