WebThe ultrasonic sensor is the heart of this Arduino-based Alarm stick. It senses the distance from the obstacle and sends this data to Arduino. Arduino further processes this data and thus determines the frequency with which the buzzer produces sound. Components you need for this project are: Arduino Board; Ultrasonic Sensor HC-SR04; Buzzer and LED WebAug 20, 2015 · IR Transmitter Circuit Diagram. We are using TSOP1738 as IR receiver, so we need to generate the modulated IR of 38 kHz. You can use any TSOP, but you need to generate IR of respective frequency as TSOP. So we are using 555 timer in Astable mode to oscillate the IR at 38KHz frequency.

Automatic AC Temperature control using Arduino and TSOP

WebNext, point a TV remote control at the detector and make sure the status LED flashes. If the status LED doesn't come on, make sure you wired the detector properly, and connected to input 2 of the Arduino. If the status LED won't turn off when you break the beam, you probably aren't blocking the IR signal well enough. WebBuy Original Arduino Boards, and Kits Online at the Best Prices in India.
