How to use infrared based music transmitter and receiver

This is a very interesting project for beginners. We had made similar project several years ago and published on BuildCircuit.COM. Check out this page. In this project, music from an audio source can be transmitted wirelessly via infrared medium.

There are two kits included in this package. One is transmitter and the other is a receiver.

On the transmitter side:

On the transmitter side, music is fed to the circuit and it is transmitted to infrared LED via an amplifying transistor so that the audio signals can be transmitted as infrared rays. If you connect a speaker in place of the infrared LED, the kit would work as a simple amplifier. (more…)

Infrared sensor with PWM

Description: In this project, Arduino first encodes the remote signals and decodes them to control LED brightness. First of all, connect the Infrared sensor as shown in the picture below. Then, press keys 0 through 4; Arduino stores the values for keys 0 through 4 and when the sketch runs, key 0 turns off the LED and the brightness of the LED increases in steps when keys 1 through 4 are pressed. (more…)

RC module

Description: An RC circuit is used to introduce time delay in circuits. A combination of resistor and capacitor gives a time constant.

The following circuit shows a basic RC circuit. In the figure C1(100uF) works as a storage capacitor. When you press the switch, the capacitor charges quickly and provides base current to the transistor Q1, that results in collector current and that glows the LED D1.. The resistance R2(1K) provides a time constant of around 10seconds. After 10seconds, the base current is not enough for driving the transistor, so the LED also goes off. (more…)

MINIBREAD

MINIBREAD is a simple technique of making electronic projects on mini breadboard. I have published basic electronic projects keeping electronic amateurs and students in mind. (more…)

How to use infrared module with Arduino

infrared module with arduino (1)

This project is similar to the following projects:

1. ON and OFF LED using infrared sensor

2. PWM experiment using infrared sensor

For this particular and the above listed experiments, you need this library: arcfn.com/files/IRremote.zip

See the following image to know how to fix the infrared sensor on the breakout board.

Datasheet of HX1838

CHECK OTHER IMAGES

Use the three dupont wires to connect the breakout board to your Arduino.

VCC pin on the board- goes to VCC of Arduino

GND pin on the board- goes to GND pin of Arduino

IN pin on the board – goes to digital pin 2 of Arduino

And a connect an LED to digital pin no. 13. As you press a remote control directing to the Infrared sensor, the LED will be switched on and off.

Upload the following sketch on to your Arduino:

Remote operated musical bell using UM3481

This article is about remote operated musical bell using UM3481. The M348X series IC is a mask-ROM-programmed multi melody generator , implemented by CMOS technology. It is designed to play the melody according to the previously programmed information and is capable of generating 16 songs with 3 instrument effects : piano, organ and mandolin. The device also includes a pre-amplifier which provides a simple interface to  the driver circuit. The M3481 series is intended for applications such as toys, door bells, music box, melody clock/timers and telephones. (more…)

Light operated switch

Light operated switch works with NE555 timer and light dependent resistor. It uses relay and toggle switch idea for operation.

Remote Operated Switch

When you press an infrared transmitter or normal TV remote control near TSOP1738 infrared sensor, the 555 timer configured in monostable mode gets triggered.
