Arduino Code for Speed Sensor In general, the following code makes Arduino to measure the speed of the moving object using two IR sensors and display the object speed in the I2C 16x2 LCD display. When ...

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

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 ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

Working Principle of ACS712 Current Sensor with Arduino The ACS712 sensor operates on the Hall-effect principle. When current flows through the input terminals (IP+ and IP-), it generates a magnetic ...

Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

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.

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

Abstract: This paper presents a measurement system with capacitive sensor connected to an open-source electronic platform Arduino Uno. A simple code was modified in the project, which ensures that the ...

In recent years, with the increasingly serious problem of environmental pollution, the demand for real-time monitoring and early warning systems in homes and industrial places has been increasing. The ...
