I'm going to show you how to make an LCD thermometer with an Arduino UNO and a LM35/36 analog temperature sensor.

This is a 360 radar using an ultrasonic sensor that saves data and encodes them onto an image.

PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small

Controls cursor using a simple joystick

A pair of talking smart glass, intended to help the visually impaired.

Build your own IoT-based water quality monitoring system WITHOUT any TDS/pH meter !!

Easy peasy reliable tachometer, that you can use to measure the rpm of tools, bicycle wheels, and robots using inexpensive parts.

This is a preliminary project that will take you through the steps I took to get the SR04 ULTRASONIC SENSOR.

Sunglasses that serve an even more useful purpose than protecting the eyes of the blind. They can help them detect objects in front of them.

It is a simple tutorial on how to create little a security device using an Arduino.

Generates maps based on distance between itself and obstacles autonomously and provides visual feedback.

A feedback control system which can control the given fluid level and display us the water level in a tank.

Use three HC-SR04 ultrasound sensors and two battery displays to show you how close the obstacles are and from which side.

Typically ultrasound sensor used to measure the range of the target, this project can locate the target in two dimensions.

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

Arduino learned how to tell the temperature

Soil moisture sensor which gives you LCD display of percentage of moisture.

Track ME is a "small" GPS, SD Card, and GSM Shield controlled by an Arduino Mega. Call me and get my location.

Very simple station that shows: Temperature, Humidity, Heat index, Carbon Monoxide, Alcohol, Carbon dioxide, Toluene, Ammonium and Acetone.

The lightmeter based on Arduino as a main controller and BH1750 as a metering cell. Information is displayed on SSD1306 OLED display.

We are going to learn a technique for building gesture-controlled laptops or computers using the power of Arduino and Python.

Clock without using RTC in Arduino with Temperature and humidity indicator

Remote temperature monitor using a Bluetooth module and an NTC thermistor. An Android app made with App Inventor is used to read data.

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