motion sensor schematic | Next Electronics

Currently working on an insect robot project. This is the first robotics project. The focus is on two methods of detecting obstacles, namely infrared (IR) and ultrasound. A decision has not yet been made regarding which method is more reliable...

LES production with automatic hand controller circuit

The circuit operates based on the interaction between an infrared light-emitting diode (VD1) and an infrared receiver diode (VD2). When VD1 emits infrared radiation, it is detected by VD2, which causes a decrease in its internal resistance. This change results...

Simple Infrared Remote Control Extender

This ultra-simple remote control extender is ideal for use with a hidden video recorder. The recorder is a Panasonic NV-SD200 and is employed as part of a camera surveillance system. A PICAXE-08-based circuit detects events and controls the recorder. Additionally,...

ir volume control

The television screen used at home features built-in speakers; however, since it functions as a computer display, it lacks an infrared receiver. This limitation prevents volume adjustment using the TV receiver remote. A recent acquisition of Stellaris LaunchPad development boards...

Battery Powered Infrared Remote Control Extender

This is a battery-powered infrared (IR) link that can be utilized in multiple rooms. The standby current is exceptionally low, resulting in excellent battery life. The circuit is designed to shut down when faced with extraneous IR radiation, effectively managing...

Infrared (IR) Proximity Detector

This is an infrared (IR) proximity detector circuit. A matched infrared emitter and detector pair is used in this circuit. The voltage-controlled oscillator is involved. The infrared proximity detector circuit utilizes a matched pair of infrared emitter and detector components to...

Infrared IR Receiver Circuit

The Infrared IR Receiver circuit consists of a phototransistor, a microcontroller, and an amplifier. Understanding the data transfer between these three components is essential for successfully operating the circuit. The phototransistor receives digitally encoded data from an IR emitting diode...

Day and Night Infrared Detection

The following is a method to allow day and night detection using Infrared/Visible light sensitive phototransistors and a simple LM339 voltage comparator circuit. A phototransistor is mounted between the rails so that it is covered by the train as it...
