An IR sensor module, which is used to detect fan’s blade to calculate the rpm, is connected to interrupt 0 means D2 pin of Arduino. Here we have used a stepper motor driver namely L293N module . IN1, ...

This project uses an Arduino Uno, a TSOP1738 infrared receiver, and an IR remote to wirelessly control an LED. When a specific button on the remote is pressed, the Arduino reads the IR signal and ...

Infrared sensor Arduino The connections for the IR sensor with the Arduino are as follows: Connect the negative wire on the IR sensor to GND on the Arduino. Connect the middle of the IR sensor which ...

An infrared sensor based prototype of self-adaptive traffic signal control system has been developed in this paper. An autonomous traffic signal system can be an effective measure to alleviate ...

As we all know by now the sensor outputs an analog signal and it's really easy to process the signal. We can use the ADC of the Arduino to process the signal and we can light up some LEDs to show the ...

It provides a complete signal path solution between a sensor and microcontroller that generates an output voltage proportional to the thermopile voltage. The LMP91050 is a programmable integrated ...

GND of the module is the common (0V) connection. 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 ...
