Rutronik Adapter Board RAB7 Sensor Fusion Arduino shield features seven sensors from Bosch, Infineon, and Sensirion Rutronik Adapter Board RAB7 is an open-source hardware Arduino shield designed for ...

A simple LED dot matrix clock project based on Arduino Nano (ATmega328), also using a DS3231RTC module and a LDR sensor.

Wasting energy by keeping the street lights on all night, we can build an affordable, high-performance smart street light system with the Arduino, LDR sensors. In this article, we'll discover how to ...

STMicroelectronics’ TSB182 dual operational amplifier is featured for high-accuracy signal conditioning with sensors, including maximum 20µV input offset voltage, 100nV/°C drift over temperature, and ...

This circuit is an especially simple op-amp application, and is a typical one for a sensor interface where a DC voltage needs to be brought into range of a microcontroller.

There are many articles about non-linear op amps being used as a comparator, but IC vendors caution against this design approach.

To use a dark sensor instead, connect LM358 ‘s pin 7 of to one of Arduino’s digital I/O pins. As a dark sensor, the circuit will output as HIGH when it’s dark and a LOW when there’s light. The output ...
