In case you don’t have an AVR programmer but you do have an arduino, the arduino can be converted into an AVR flash programmer, meaning it can program bare AVR microcontroller chips. Say if you have an AVR chip and you want to program the chip, so that the program that you’ve written and compiled […]

Close Encounters of the Curiously Minty Kind. This Instructable will show you how to build an Altoids version of the ‘Close Encounters’ mothership, and how to interact with it. This may be vital training for that day when the Bright White Beam comes to suck you up into the unknown. It will also introduce you […]

An infrared (IR) distance sensor is a sensor that can measure distance from a solid or physical object. An infrared distance sensor does this through light waves. It sends out infrared light and waits to receive it back at the receiver end. If it receives back the infrared light, this means that the light waves […]

In this project, we will go over how to build a carbon monoxide sensor circuit with an Arduino. The sensor we will utilize is the MQ-7 sensor for detecting carbon monoxide. This sensor is responsive to the impacts of CO. Carbon monoxide (CO) is a highly hazardous gas that lacks odor, color, and taste, making […]

An ultrasonic distance sensor is a sensor that can measure distance from a solid or physical object. An ultrasonic range finder does this through sound waves. It sends out high-frequency sound waves and then waits to listen back for these sound waves. If it has heard back these sound waves, then this means the sound […]

In this project, we will go over how to build a servo motor circuit using an arduino. This is a circuit which can control and rotate a servo motor to rotate a certain amount of degrees. Specifically, in our circuit, we will make it so that the servo motor rotates 180 degrees and then stops […]

In this project, we will show how you can build an ohmmeter using an arduino. An ohmmeter is a device that can measure resistance. Most of the times now, ohmmeters aren’t standalone devices but appear as one of type of measuring device amongst many in a multimeter. An advanced multimeter, today, would have an ohmmeter, […]

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 […]
