Our schematic consists on 3 elements which are: Photoresistor (LDR), Piezo Buzzer, 1 – 10 kΩ. The LDR can be connected any way you want because doesn’t have polarity.

Just connect an piezo to the board and you are good to go. Pin 11 is used in every sketch because some piezo speakers can be connected between it and the close GND pin without any wiring. You can use ...

Materials Required Arduino Uno Piezoelectric transducer 1N4007 diode Capacitor (10 µF or 100 µF, 25V) LED Resistor (220 ohms) Breadboard and jumper wires Circuit Diagram Description Piezo Transducer: ...

Here is a simple general-purpose security alarm circuit built on the Arduino platform. It brings up an obtrusive alert signal when an intrusion/theft attempt is observed by its front-end sensor. In ...

This paper presents the performances of rainfall energy harvesting through the use of a piezoelectric transducer and an Arduino-based measuring system. Different studies agree on the possibility of ...

Spread the loveSchematic drawing software for Arduino, Raspberry Pi, and other Single Board Computers (SBCs) is essential to developing electronics projects. When it comes to creating circuits on a ...

This week, with a little help from a Roomba, [Dino] built a guitar pickup and preamp that sounds marvelous. A pickup takes vibrations from the guitar and turns them into an electrical signal which … ...
