Currently working on an insect robot project. my first robotics project! I`m looking into 2 methods of detecting obstacles i. e. IR and Ultrasound. I cannot seem to choose at this point in time! Can someone give me some guidelines as to which is more.... -
his remote transmits a tone using an infa-red LED. This tone is decoded by the receiver. Since the receiver only switches when it ""hears"" the tone, there are no accidental activations.... -
As I was developing my IR Extender Circuit, I needed to find a way of measuring the relative intensities of different Infra red light sources. This circuit is the result of my research. I have used a photodiode, SFH2030 as an infra red sensor. A MOSFET.... -
Most of the IR remotes work reliably within a range of 5 metres. The circuit complexity increases if you design the IR transmitter for reliable operation over a longer range, say, 10 metres. To double the range from 5 metres to 10 metres, you need to.... -
Most homes today have at least a few infrared remote controls, whether they be for the television, the video recorder, the stereo, etc. Despite that fact, who among us has not cursed the light that remained lit after we just sat down in a comfortable chair.... -
Normally home appliances are controlled by means of switches, sensors, etc. However, physical contact with switches may be dangerous if there is any shorting. The circuit described here requires no physical contact for operating the appliance. You just need.... -
The IR detector (IC3) controls an LM 7555 CMOS timer (IC2) which operates in mono stable mode. When the beam is broken, IC2 is triggered and its pin 3 output goes high for about half a second. This extinguishes LED1 and turns on transistor Q1 to drive a 5V.... -
Men in particular enjoy the convenience of television remote controls often to the annoyance of their female partners. Men apparently want to know what they re missing when the TV is tuned to a particular program, so they like to keep zapping to other.... -
Using this circuit, audio musical notes can be generated and heard up to a distance of 10 metres. The circuit can be divided into two parts: IR music transmitter and receiver. The IR music transmitter works off a 9V battery, while the IR music receiver works.... -
Here is a very simple infrared detector circuit which can be used to detect infrared light. The circuit is consist of only three components a RS-276-145 photo transistor, 330 Ohms resistor and a general purpose LED (Light Emitting Diode). When the photo.... -
Do you know how infrared motion detector alarm Whenever someone comes in the infra-red zone. Infrared motion sensor, which detects moving human body. The alarm will sound automatically. The detection zone coverage is 80 degrees horizontally to 8 meters.... -
About a do-it-yourself alarm arrangement body with PIC18F452. It`s a abundant amusement activity although the schematic is actual complicated. This activity uses three capital accessories to actualize the claimed alarm system. The IR Ambit sensor gives.... -

This circuit can be built from readily available low-cost components, some of which may even be hiding in your junk-box! The indicated value of 22 for resistor R1 causes an average current of about 65mA through infrared emitter D1. Because the IRED is.... -
This ultra-simple remote control extender is ideal for use with a hidden video recorder. The recorder is a Panasonic NV-SD200 and is used as part of a camera surveillance system. A PICAXE-08-based circuit is used to detect events and control the recorder. It.... -
All modern IR remote control devices produce a continuous coded stream of pulses at 37. 9 kHz when any button on the module is pressed. These IR pulses are detected and decoded by a receiver (your TV, VCR etc. ) and the appropriate function activated. In our.... -
There are so many circuits available for infrared Burglar alarm but transmitter section of these burglar alarm circuits are complicated and you may have assemble it yourself. But here is burglar alarm circuit that uses the ordinary DVD remote as the.... -
The circuit depicted here forms one half of a device that will prove extremely handy when tracing the path of electrical wiring in a building or to locate a break in a wire. The system is based on similar equipment that is used by technicians in telephone.... -

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
