In this project, we will go over how to connect a microphone to an arduino so that the arduino can detect whether there is sound in the environment or not. This circuit is only capable of detecting whether there is sound in the environment or not. It won’t be able to record the words that […]

Spectrographic Auroral Indicator – A Northern Lights Warning Device using arduino
3/16/2011 EDIT: The Wing Kp Predicted Geomagnetic Activity Index model is now deployed and operational. Costello is now considered non-operational and will be discontinued on 23 Mar 2011. Comments and questions are welcomed at [email protected] The Wing Kp Predicted Geomagnetic Activity Index model is known to perform well for large geomagnetic storms and includes both […]
How to Integrate a Temperature Sensor Circuit to an LCD
In this project, we will go over how we can build a temperature sensor circuit and integrate it to an LCD so that we can get a readout of the temperature on the LCD. In previous projects with temperature sensor circuits, we built the circuit and then got a readout on the computer that we […]
How to Build a LM335 Temperature Sensor Circuit
In this project, we will demonstrate how to build temperature sensor circuit using a LM335 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay this temperature to us back in degrees Kelvin. The difference between an LM335 and LM34 and LM35 temperature sensors is the LM335 sensor […]
How to Build a TMP36 Temperature Sensor Circuit
In this project, we will demonstrate how to build temperature sensor circuit using a TMP36 sensor. As a temperature sensor, the circuit will read the temperature of the surrounding environment and relay the temperature to us back in degrees fahrenheit. The IC we will use to measure the temperature is the TMP36 IC. We will […]
Hard Drive Persistence of Vision (HDPOV) using arduino
The platter of a hard drive spins well over sixty times a second. If a narrow slot was cut into the platter to allow LEDs to shine through, we can achieve flicker fusion and trick the eye into seeing a stable image. This phenomenon is known as persistence of vision (POV). There are many examples […]
How to Drive a 7 Segment LED Display with an Arduino
In this project, we will show how to drive a single 7 segment LED display with an arduino microcontroller. A 7 Segment LED Display is an electronic device housing 8 individual LEDs. Using this device, we can display all numerals and many alphabetical characters and many more types of symbols. The 7 segment LED is really a […]
Low Cost Water Flow Sensor and Ambient Display using arduino
Water is a precious resource. Millions of people do not have access to clean drinking water, and as many as 4000 children die from water contaminated illnesses every day. Yet, we continue to be wasteful with our resources. The overarching goal of this project is to motivate more sustainable water use behavior and raise awareness […]
How to Build an RGB Full Color LED Module Circuit
In this project, we are going to build an RGB Full Color LED module circuit. A full color LED module is a circuit in which an LED can be lit to any color. This is why it is called a full color LED module. By programming the module with a microcontroller, we can program the […]
Super Simple Beginners Robot! using arduino
I created this Instructable for the absolute n00by robot wannabe. I have noticed a huge jump in the number of beginners getting into the hobby and the number of “how do I” questions seem to be mounting. Maybe this humble little Instructable will help one or two create their first robot. You will find basic […]
