The Arduino Sketch (code) uses the external interrupt (int 0) on Arduino’s digital pin 2 (D2). This is used to read the output pulses coming from the water flow sensor. When Arduino detects the pulse, ...

The DS18B20 library supports only the DS18B20, only one sensor per pin, no parasite mode, no Fahrenheit and no alarm functions. The only feature the class supports is the asynchronous reading of the ...

Arduino is an open-source platform that consists of a hardware board and a software IDE. Arduino boards are microcontrollers that can read inputs from sensors, buttons, switches, and other devices ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

This sensor is built for detecting ppm of certain gas molecules, such as VOC, ethanol, ammonia, Hydrogen sulphide, etc. This sensor can't distinguish different gas molecules. Please use the table ...

Learn the advantages and disadvantages of using analog and digital sensors with Arduino for mechatronics projects. Find out how to interface, calibrate, acquire, troubleshoot, and select sensors ...

Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.
