Experimenting with air-writing recognition on Arduino’s smallest board

This is a 3D Scanner. An ultrasonic sensor is rotated by the servo motor. The object to be scanned is revolved by a motor. Plots in Python.

Measuring temperature and humidity featuring LC display and webserver upload using Arduino with Ethernet shield, LCD and realtime clock

Super simple Weather station containing only two components.

This Portenta things have become like an addiction here I post a new project where I used a thermocouple sensor through my Arduino Portenta.

Build a simple shutter speed tester for film cameras.

Plantoolighter is a system which redirect sunlight to the plants which are adjacent to garden wall and unable to get proper sunlight.

Weather forecaster, which displays the weather forecast on the screen in the form of descriptive text.

A simple VU meter realized with only mechanical typical items, as screws or nuts, but powered by Arduino!

In this case, it is interesting that are used two sensors to scan the entire 360-degree space.

Pressure tendency can forecast short-term changes in the weather. This is a very sophisticated device designed for sailors, yachtsmen, etc.

Variometer is instrument that indicates the changes in the altitude variations.

On this project I will show you how to measure the speed of movement of an object using HC-SR04 ultrasonic sensor.

Monitor to record temperature and humidity, store 24 hours history and display these in a graph. Battery level monitor screensave.

This is a thermometer intended for measuring the temperature in the room where we are staying, also known as room comfort thermometer.

A very low power consumption rechargeable temperature and humidity monitor that can run off a rechargeable battery for 12 days or more.

This simple Arduino project can limit the number of people inside a shop and maintain social distancing in an automated contact free way.

Use an ESP32 Cam and a passive infrared (PIR) sensor to create a motion-activated security camera that posts photos to a Discord channel.

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

Use a ratiometric linear Hall effect sensor to build simple magnetic field strength meter.

Protect your projects by making them fingerprint-secured with sleek, compact and fast ID809 Capacitive Fingerprint Sensor.

Better code for the MMA8452Q

Using Arduino and the sensors I analysed how a small air humidifier can change the parameters of the room and influence health state.

Use to record somebody's blow strength. Since without calibration it is relative value.
