Burning LED

hi guys! this time I want to show the results of my project, i.e. led intensity. led intensity is a condition where the intensity of the LED changes every 200 milliseconds. make the value of the LEDs vary so that the LEDs look like a burning object. Without a long wait, let's see how to assemble them.

Step 1: Step 1:Materials Needed

1. 1x 9V battery
2. 1x Arduino UNO
3. 4x LED
4. 1x Half breadboard
5. 2x jumper wires
6. 1x Battery holder with power jack
7. 1x USB type A to type B

Step 2: Step 2:Stringing Components

arrange the components you provide. don't place the polarity (cathode-anode) wrong. Because it can cause this project to fail.Anode to digital 5.Cathode to GND.

Step 3: Step 3:Code

this project is very dependent on the code provided. Here is the code that must be uploaded to Arduino:

const int PIN_LED = 5; // Pin PWM

void setup() {

pinMode(PIN_LED, OUTPUT); }

void loop() {

int nilaiAcak = random(176);

analogWrite(PIN_LED, 60 + nilaiAcak);

delay(200); }

Step 4: Step 4:It Works!

This project should be successful. If it doesn't work, maybe you are not careful enough. Look at the circuit or code.
