Arduino

Arduino is an open-source physical computing platform designed to make experimenting with electronics more fun and intuitive. Arduino has its own unique, simplified programming language, a vast support network, and thousands of potential uses, making it the perfect platform for both beginner and advanced DIY enthusiasts.

Circuit 1

Process

This is what circuit 1 looks like before any changes to the code

This is what the incomplete sketch looks like

This is what the complete sketch should look like

Circuit 2

Product

A potentiometer is like a control knob. It works like a control that you would use to change the volume on something. It changes resistance based on how much it is turned. By using it as a "voltage divider", the Arduino board can sense the position of the knob, and with that value, you can control anything you would like. As demonstrated in the video

This is what the complete circuit diagram looks like.

Circuit 3

Process

This is what the Circuit looks like before modify the Sketch

This is what the Circuit looks like after modifying the Sketch

This is what the Sketch looks like before the light is properly working

This is what the complete sketch looks like

Circuit #4 - Multiple LEDs

Product

This is what the sketch looks like without editing the code

This is the oneOnAtATime () command

It makes the lights turn on one at a time

This is the pingPong () command

It makes the lights bounce back and forth creating a ping-pong like effect

This is the randomLED () command

This is the code that makes the lights turn on at random

This is the marquee () command

It creates a lighting effect in what we see on rail road lights

Circuit #5 - Push Buttons

Product

This is what the code looks like to make the circuit work

As long as 1 button is being pushed the light will turn on

Circuit #6 - Photo Resistor

Process

This is what the sketch looks like before changing the Photo resistor ranges. As you can see in the video, the light does not completely turn off because the ranges that control the resistor prevent it from doing so.

As you can see the map(lightLevel) funtion has a range between (0, and 1023). That prevents the light from completly shutting off

Product

By changing the range of the map(lightLevel) function to a lower number, you can make the resistor recognize the light already present. And by covering the resistor with a finger or a hand, it can recognize the change in light level, causing the LED to turn on and produce light.
