I found limited documentation on the usage of a color sensor I recently purchased, so here is my attempt to make it more simple.

Someone has been eating my cookies! Thankfully Arduino is here to help find out who it is.

Water quality, anywhere, anytime!

An Arduino electromechanical barometer.

During the summers, many people get sunstroke because of playing in the sun for too long. So this device will prevent getting sunstroke.

This is an Arduino Uno with a DHT11 temp/humidity sensor with and LCD screen powered by a power bank.

Clock without using RTC in Arduino with Temperature and humidity indicator

My project helps visually challenged people to walk without crashing into walls and obstacles.

A standard speaker can be used to detect vibrations and send data to a microcontroller.

Glowing LED to detect the increase in pressure by pressure pad using Arduino.

When you put anything in front of your mobile camera and push the button, your mobile will say the color of that thing.

Short and easy, read distance 2 - 400 cm and plot it in I2C OLED screen.

This is tutorial to help you understand ultrasonic and buzzer and go deeper into learning Arduino, follow these steps and give me feedback.

It reads from up to eight temperature sensors (DS18B20) and displays on the LCD display (16x2)

How to build a device for estimating blood alcohol content from a breath sample. Developed with Zerynth and an ARM board.

Clouds meter <> establish the height of clouds through an IR measurement temperature of saturation.

Like a real pyranometer, realize a measurement of sun power.

This device measures fine dust and NO2 concentration in the air while on the move and adds GPS coordinates to each measurement location.

Build a weather station with Arduino & ASP.NET Core.

I built an Arduino Weather Station. It uses a DHT 11 (it will also work with DHT21 DHT22).

Basic weather system, in/out temp and humidity with heat index, dew point, pressure and weather prediction and time and date.

Worried about the quality of air around you? This project will help you monitor the air pollution levels in your surroundings!

An Arduino Uno with DHT11 sensor module, three LEDs and a Piezo speaker.
