Here is a smart room. The room is smart because the sensors detect different situations. When the room is very hot, the sensor makes the LED blink. When someone enters the room, the alarm rings. At night, the sensor turns on the light. From this project, I learned how to make a project using different sensors

Here, the sensor senses the temperature and shows it on the Serial Monitor

Here, the LED and buzzer turn on when I move my hand. When I do nothing, the LED and buzzer do not turn on. I learned how this sensor works

When I move my hand in front of the sensor, the LED glows. When I do nothing, the LED does not glow

In this project, when I put my hand in front of the sensor, the ultrasonic sensor detects it and the LED glows

When I put my hand within a 20 cm range, the LED glows. I learned how we can use this sensor in different projects

Here, the ultrasonic sensor measures the distance and shows it on the Serial Monitor. I learned how an ultrasonic sensor works and how we can measure distance using it

Here, when I put my finger on the sensor, the LED turns on. This means that when it is dark, the LED turns on, and when there is enough light, the LED turns off. I learned how smart lights work and how many houses use this type of automatic lighting

In this project, the LED glows when I do nothing. When I put my finger over the LDR sensor, the LED turns off. This means the LDR senses brightness or light. I learned how an LDR works and how it detects light

Here, the Serial Monitor shows the brightness detected by the sensor. I learned how an LED sensor works and why we use this sensor to detect brightness or light

The LEDs glow in different patterns when I press the button. I learned how a push button works

Here, we distributed the LEDs and resistors, giving each LED one resistor. I learned how to use resistors properly

When I rotate the potentiometer, the LEDs glow one by one. From this, I learned how to use a potentiometer to control multiple LEDs

Here, the potentiometer values are shown on the laptop. I learned how to read the potentiometer values and how to solve problems because I faced many problems while making this project

Here, I can control the speed of the LED blinking. I properly understood how to use a potentiometer.

When I turn the potentiometer, the LED glows with different levels of brightness. When I turn it back, the LED changes its brightness again. I learned how a potentiometer works in a project and how it can be useful in different projects

When I press the button, the buzzer makes a sound for 3 seconds and then turns off. From this, I learned how we can do many different things with a push button

Now, the LED glows when I press the button and turns off when I press the button again. I learned how a push button helps us control the power of an LED

I learned how a push button works with an Arduino I didn’t know what a push button was before Here, when I press the button, the LED glows This helped me understand how a push button controls an LED

Here, the LED glows without a resistor, but it gets hot. When I add a resistor, the LED works properly. So, I learned the importance of using a resistor with an LED

This time, I made a pattern like Diwali lights. First, all the LEDs glow together, and then they glow in two pairs. I learned how LEDs work, how to make Diwali-style lights using an Arduino Uno, and how to write Arduino code

Here, the LEDs glow one by one and then glow together. This happens repeatedly, and I understood properly how LEDs work

The LEDs glow in a line, one by one, with different colors like Diwali lights. I learned how to make Diwali-style lights

All the LEDs turn on in sequence. First, the first LED glows, then the second, and so on until all the LEDs glow. It looks like Diwali lights, and I learned how Diwali lights work

The LEDs glow in two pairs. I understood how to change the code and make the LEDs glow in two pairs

So, I programmed the LEDs to glow in this pattern. I learned how HIGH and LOW work, what they mean, and why HIGH and LOW are important for controlling LEDs

I arranged 8 LEDs so they blink one by one. I learned how to make all 8 LEDs glow one by one, and I also understood how the code works

First, LED 1 glows while LEDs 2, 3, and 4 are off. Then LED 1 turns off and LED 2 glows. Next, LED 2 turns off and LED 3 glows. Finally, LED 3 turns off and LED 4 glows. This process keeps repeating

so here the 3 LED also blink the 1 LED blink and then 2 and 3 LED also blink so i learn how we do cod for to bling 3 LED

This happens because the first LED glows while the second LED is off. Then, the first LED turns off and the second LED glows. This process keeps repeating.

so now the led blink but it on for 0.5 second and OFF for 1 second this happening

so now the LED glow for 3 second and off for 1 second it happening

same thing but the LED for 0.5 second and it off and again the LED glow

i learn how this cod work and how do this LED delay that I learn from this

i lurn and understood how Breadboard

I also understood how Breadboard work

i understand properly how Breadboard work

I learn how we pass Electricity in Breadboard

i understand how to use Breadboard and when we have big project how Breadboard help us

I understood how to work led in arduino how i change delay in cod
