Circuit Splash

In this project we are going to make Clapper circuit using the concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. We are going to use a MIC and Uno to sense the sound and trigger a response. This Clap ON Clap OFF switch basically turns ON or OFF the device, by using the clap sound, as switch

We have built a Volume Meter or VU meter, with the help of MIC, OP-AMP and LM3914, which glows the LEDs as per strength of the sound, if sound is low, lesser LEDs will glow, and if sound is High more LEDs will glow, check the Video at the end. VU meter also serves as a volume measurement device.

In this instructable i will explain how to build a simple 555 circuit that will blink a led and sound a buzzer, this has many application for example you can connect an LDR between the power source and the circuit and then put it in your closet where it is dark and when someone opens the closet the alarm will sound

In this project, we are interfacing Mercury switch / Tilt sensor with Arduino UNO. We are controlling a LED and buzzer according to the output of the tilt sensor. Whenever we tilt the sensor the alarm will be turned on.

The purpose of electronic circuits is to control the flow of electric currents. This may sound like a silly question, but why do we need to control the currents? Well, it has been found experimentally that the intensity of various electrical effects is related to the amount of the charge Q that passes by a certain region per unit time.

Learn how the build your own WiFi switch with the ESP module and how to control any appliance of your favorite place.

An ATMega32 sound generator code is extremely simple to implement. Almost any GPIO pin can drive a piezo buzzer, and the output quality is fine for producing some beeps. The code shown here is the simplest one I remember using basic physics, and since it does not use PWM it could be implemented on almost any microcontroller.

Here a tone generator project is developed using Arduino Uno. A few number of buttons are interfaced with the UNO and each button generates different intensity of tone. The frequency of tone generated by the UNO is same at every internal. It’s the intensity of the sound which changes with each press.
