“Hi guys, we will make an interesting project in this project. We will try to make a flame by snapping our finger.Let’s get started on the project.
First, let’s create a prototype. I will use Arduino Nano for this project. You can use any Arduino model you want. The source codes will work on all of them.
Parts Required for Prototype:
1x Arduino Nano V3
1x Sound Sensor Module
1x IRFZ44N Mosfet
2x 3.7v Battery 18650
1x Battery Holder 18650
Matches and Candles
Let’s put the Arduino Nano on a breadboard. Next, let’s plug in the sound sensor.
We need a Mosfet for switching and power balancing. Also, we need a resistor to use with Mosfet.
Next, I’ll use an LED to adjust and see the sensitivity of the sound sensor. Actually, LED is just like a flame trigger. Of course, I add a resistor that I will use only for LED.
Yes, we’ve completed all the components. Let’s start making connections.
Sound sensor VCC to Arduino +5V
Sound sensor GND to Arduino GND
Sound sensor OUT to Arduino Digital 10
Mosfet & LED:
Mosfet Pin 1 (Gate leg) to Arduino Digital 9
Mosfet Pin 1 to 10K Resistor
10K Resistor other leg to Arduino GND
Mosfet Pin 2 (Drain leg) to LED (-)
LED (+) to 220 Ohm Resistor
220 Ohm Resistor other leg to Arduino VIN
We’ve completed the connections, now let’s take a closer look at the source code.”
