Aquarium Auto Refill With Arduino

“This Arduino Pump Tutorial shows a simple example of how to use a float switch and RobotGeek Pumping Station to refill a reservoir once the level gets too low. For our example we use a small aquarium, but this same …

Arduino Soil Probe using DS18B20 and DIY Moisture Hardware

“As a fanatical gardener or a professional farmer, knowing the environmental conditions of our soil is invaluable. Obviously, we can’t measure the number of worms or pieces of organic humus, but we can measure temperature and moisture content really …

Decorative LED Table Top

“This is my first project for my Interactive Design class where I play upon the Light Up Disco Table decoration by turning it into a prototype for an Interactive game using a Hall Sensor as the trigger. This is my …

DIY PCB 4 channel IR remote controller

“in this posting, i can share PCB 4 channel remote controlled with IR sensor, using atmega 328, programmed with arduino uno R3.”

Project  OBD Reader

OBD Reader

“This was a project for one of my college courses. I decided to make an OBD II reader that will allow me to connect to the car computer and access different values! This project has the original code posted here …

Smart Humidifier (make Your Room Comfortable)

“There are three key components to healthy air. It must be fresh, clean, and have the proper humidity. Humans are sensitive to humidity because the human body uses evaporative cooling, enabled by perspiration, as the primary mechanism to rid itself …

Wearable Infrared Thermometer

“This Instructable will demonstrate how to make a wearable, mobile earpiece thermometer. This thermometer will use an infrared temperature sensor, and relies on tympanic radiation to acquired temperature readings. These readings will be able to be stored using an SD …

Weather box using arduino ~the easiest

“The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins …

Full Digital Clock With Presence Sensor (RTC - Alarm - PIR - Temperature - Humidity - Dew Point)

“I already have done some digital clocks projects with Arduino including LED and LCD displays, but this one is more special because I have introduced a new feature with a movement sensor (PIR).”

Precise Air Quality Monitoring System (Portable)

“In this Instructable, I will walk you through the steps to build an Precise Air Quality monitoring system. It consists of an Arduino R3, 2 Grove sensors along with 2 other MQ gas sensors to keep the data in check …
