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:

This is circuit 1, where we use coding to create a blinking light with an LED. The code loops the program to continuously light it up.

The code shows the delay of the LED being controlled by 'sensoryValue' which is the variable of analogRead(sensorPin). This shows the blinking is on loop but being soley controlled by the potentiometer for the blink rate.

Circuit 2:

This is circuit 2. Using the potentiometer, the LED blinks at different paces. The potentiometer dictates the rate the LED blinks and controls the light to blink faster or slower.

Circuit 3:

This is circuit 3, where we had to show the spectrum of colors through a 4-legged LED. The different colors are created by the different legs of the LED lighting up at the same moment. The spectrum fluently lights them up to create a pattern.

Arduino changing colors with the delay of 0.001 seconds with showSpectrum.

The code here shows that by changing the spectrum delay, the colors shift in a faster way. I set it to 0.001 because I wanted to get epiliepsy but did not.

LED's lighting up one by one in a pattern, the almost replicating ping-pong effect but still much different.

Circuit 4:

This is circuit 4, where different LEDs were programmed to turn on at different times. On the left, the LEDs light up one by one. On the right, the LEDs light up randomly.

The two different codes are helpful for different ways to get the same.

It looks like a pattern but this code randomly lights up, the code choosing a random LED to light in order to create a random pattern.

Circuit 5:

This is circuit 5. In circuit 5, pressing either of the two buttons will light up the LED. Pressing both at the same time will cause the LED to shut off.

Pressing the right button, then the left button, then both.

The light is only slightly brighter because the room is so bright already, but the effect is visible in the growth of brightness. Sensors are coded to grow in brightness under darkness and with light, are signaled to lower the effect.

Circuit 6:

This is circuit 6. On the left is the LED turning brighter under darkness slowly. On the right, the LED turns on almost instantly under darkness and off under light.

Only delaying slightly, the light turns on under the hand and on under the light. Sensors take in the light and send that signal to turn it on or off.

The LED lighting up as the temperature reaches over 70 Celsius, this did in fact worry me as the heat had burned my fellow classmates.

It isn't show, but there is an accessibility where we are allowed to see the temperatures of the tempPin every second in order to see where the code works and create the possibility of trial and error.

Circuit 7:

This is circuit 7, where the temperature of the tempPin going over the heat limit will turn the LED on.

Circuit 8:

This is circuit 8, a fan-like motor that spins according to the coding. I had tweaked the coding in order to make the fan change directions in a much slower way, but reseting its position with hace.

Servo spinning irregular because of horrendous code.

Unfortunately, I was unable to save my code for this tune. The piece playing is jigglypuffs lullaby from Pokemon. I love this circuit because our classroom was filled with sweet sounds.

Circuit 9:

This is circuit 9, the best circuit. Circuit 9 uses the Piezo element and a bit of code to play familiar tunes.

Circuit 10:

This is circuit 10, where we program a motor to spin a flag. These are moved by the currents of the transistors.

Motor spinning a flag and minimumly stopping because of the code.

The recording is a bit bad because this is recorded off of another tablet. The reason behind this was technical difficulties and working with what I had.

Circuit 11:

This is circuit 11, where like indicators, the LEDs light up back and forth with a ticking noise to signal the switch. Unfortunately, the sound is unable to be picked up and the light of the yellow LED is not bright enough to be seen.

Ping-Pong, the LEDS flashing one by one.

Circuit 12:

This is circuit 12. It is similar to circuit 4 but the amount of LEDs is doubled.

The code on the left is Ping-Pong, where the LEDs light up one by one as if they are passing the spark.

The codeon the right is Random-LED, where randomly, one by one the LEDs begin to light up in no specific pattern.

There is a god-awful amount of jumpers and LEDs and resistors, but very good mental strength and growth.
