In this video, I’m building a LoRaWAN Class A sensor node using an ESP8266, BME680 environmental sensor, and REYAX RYLR993 ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

This project shows how to build a light gauge that uses an LED bar graph to show the measured brightness level. The function “gauge()” is a good example of using “if” statements to analyze sensor ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. [Udo] hit upon the idea of pulsing a laser pointer and measuring the time of the ...
