I made this project where as i rotated the potentiometer, the servo also rotates. I understood how the code takes the values of potentiometer and accordingly rotates the the servo

I learned how a servo moves with it gears on angles like 0, 45, 90, 135 and 180.

I built a distance reading circuit and in this project I learnt how the uktrasonic measures distance by sound waves.

It was a very fun challenge as I llearnt to use the serial plotter for the first time. I learnt how the graphs form when we tell it to print different labels and mark its readings.

I built an environment monitor circuit that combines dht11 and ldr module and shows the reading on a lcd display. I faced problem in lcd display but it soon got solved as I realized I had not installed the Liquid Crystal_I2c library

I connected a ldr with lcd display for the first time and learnt how to show values in numbers from a sensor even if it does not have a A0 pin.

I understood about the rows and coloumns of a lcd display and learned about the potentiometer on the back of the lcd display module

I BUILT A SEVEN SEGMENT DISPLAY COUNTDOWN TIMER WHERE i UNDERSTOOD HOW OUR CODE EXPLAINS THE PATTERNS TO DISPLAY BY SHOWING 1 AND 0

I built a button controlled 7 segment display where I applied the logic of my 40 project and just added a button. I also understood that how with every click the code changes the number

I made my first project with a single digit seven segment display

I combined the knowledge of all projects done in 31 to 39 projects and made this project .

I got introduced to DHT11 temperature sensor for the first time.

It took me a long time to make this project as I understood about the possible challenges I might face while working with a pir motion sensor

I learn how to use motion sensor and the basic system of automatic night lamp

it took time in making as my ultrasonic sensor was not working but soon with a new ultrasonic, I made a buzzer led parking assistance

I built a miniature parking assistance provider with ultrasonic sensor and led

I made a real time working distance measurement ciruit that show distance betwen objects in serial monitor

I learnt how to debugg the code of ldr where my project was working invertedly.

I made my first ldr project in the form of an light lamp

I learnt how to use a light dependent resistor

I made a button powered led blinking system which was very easy making after the so much prior knowledge about buttons and leds

I made a rgb led controlling potentiometer circuit.

I enjoyed making a potentiometer led LED selector. I understood how the code made different values for the amount of rotation the potentiometer has had and on that basis it selects which LED to glow.

I learnt how there are different readings in the serial monitor when we rotate potentiometer

I built a circuit where rotating the potentiometer changes the blink speed of led

I took time to make and understand this potentiometer led LED but I made it. I worked with potentiometer for the first time

I built a button powered buzzer that buzzes for 3 secs when we toggle the button

I built a button powered led circuit and it was fun making a similar light system like our house light system

I learnt how to use a small bottun and connect it with led and arduno

I learnt how to power a led with the 5v and gnd pin of arduino.

I built a led system using my own code.

I built my own patterned led blinking system.

I built a diwali light-like led chase

I built a led system where leds stay on untill all the leds are on and then they all turn off; the loop continues

I learnt how to make a led pattern with 6 leds where two leds blink at once

I understood and built a pattern led led chase.

I understood the array and loop function in the code and made a led chase with 8 leds.

I built a 4 led chase with 4 leds, 4 different digital pins on arduino and a simple code

I learnt to make a 3 led chase with just some prior knowledge about code and leds

I created a led chase with 2 led. I learnt that two do this challenge, we need two different digital pins for led

I learnt how to customize the blinking speed of led.

I controlled the blink of led according to my time (4 sec and 2 sec) which was felt quite simple after the projects done in challenge 7 and 8

I learnt how to fasten the speed of the blinking of led. I learnt that the time in code is written in milliseconds.

I learnt to decrease the blinking speed of a led. I learnt to understand the led blink code

I learnt making a circuit consisting of 8 blinking leds which blink in sync. In the project some leds were not working as they probably got overpowered.

I created a 5 led blinking project where I learnt to connect the side power rails to middle power rails.

I learnt to connect 4 different leds on breadboard and connect it with arduino to power it. The leds were blinking in a sync

I understood the power rails in a breadboard.

I started using breadboard and connect it with arduino through jumper wires.

I built a simple arduino connected blinking led. I understood that the shorter wire which is the negative terminal always goes in the GND
