IR Sensor Pinout. The IR sensor has a 3-pin connector that interfaces it to the outside world. The connections are as follows: VCC is the power supply pin for the IR sensor which we connect to the 5V ...

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, ...

Analog signals – directly measurable quantities in terms of some other quantity. Examples: Thermometer – mercury height rises as temperature rises Car Speedometer – Needle moves farther right as you ...

This project demonstrates the design and programming of an electronic circuit using the LM35 analog temperature sensor with Arduino. The circuit reads temperature values from the sensor and displays ...

In the electronic tongue which we have proposed to develop will consist of an IR sensor which will ... and the sensor has been incorporated in the arduino board where different color LED's has been ...
