Raspberry Pi HATs offer small, stackable data acquisition with features like analog and digital I/O.

Quantizing - breaking down analog value is a set of finite states Encoding - assigning a digital word or number to each state and matching it to the input signal There are ... General specifications ...

The digital signal output to be detected (usually marked as DO in the module) is applied to D2 input of the Arduino. Analog output (marked as AO) from the module is not used here. Sensor-head of the ...

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 ...

One advantage of using Arduino as a security system is the flexibility ... The alarm system is triggered when a “Logic High (H)” level signal is detected at its sensor input port. As indicated, our ...

The device includes the connection between an Arduino microcontroller and an optical mouse sensor to provide help in reading the movements from horizontal and vertical directions. The Arduino board ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

At the start, the message is printed on the screen that guides the user to choose the sensor through a keypad. The user has to provide the input at the TestPin and the output is fed into the Arduino.
