In this project, we will go over how to build an alcohol sensor with an arduino. The alcohol sensor we will use is the MQ-3 sensor. This is a sensor that is not only sensitive to alcohol, particularly ethanol, which is the type of alcohol which is found in wine, beer, and liquor. This type

In this project, we will go over how to build a smoke sensor circuit with an arduino board. The smoke sensor we will use is the MQ-2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ-2 smoke sensor reports smoke by the voltage level that it

In this project, we will build a liquid level gauge circuit with an arduino. This is a circuit in which a liquid level can be monitored through a gauge. We read the liquid level from the gauge (low, medium, or high), just as you see above. With a microcontroller such as the arduino, building this

In this project, we will go over how to connect an analog volt panel meter to an Arduino so that it can measure and give us a readout of light striking the circuit. In this way, the circuit will function as a light meter. When there is a lot of light shining on the circuit,

In this project, we will go over how to build a heat detector circuit using an Arduino. A heat detector circuit is a circuit, of course, which can detect the presence or absence of heat. This could be useful for a wide range of circuits including any device that needs monitoring and protection from excess

Build a strobe tuner with an integrated tone generator to teach tuning by ear. -=Background=- I have always dabbled in instruments. Over the course of my life, I’ve attempted (with varying success) Piano, Guitar, Banjo, Penny Whistle, Ocarina, Panpipes, Great Highland Bagpipes, Smallpipes, and Didgeridoo (don’t ask, It was late, and I was a bit

Wish you were bat? Want to Experience Echolocation? Want to try to “see” with your ears? For my first Instructable, I will show you how to build your own ultrasonic Batgoggles using an Arduino microcontroller clone, Devantech ultrasonic sensor and welding goggles for around $60 or less if you already have standard electronics components. You
