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 - Blinking an LED

This is a diagram for the completed circuit for circuit one.

This is a video of my working Arduino Circuit, which is the LED blinking.

This is the sketch for the working circuit, with a delay of 1,000ms that can be changed to blink faster or slower.

This is the changed sketch to make the LED blink faster.

This is the working Arduino with manipulated code to make it blink faster.

Circuit #2 - Potentiometer

This image demonstrates where to put the wires and potentiometer.

This image explains how it works.

This is the sketch for the potentiometer. The code helps determine the speed of the blinking LED according to the potentiometer.

Product

In this video, I built a model using a potentiometer, one LED, 6 jumper wires, and a resistor. The potentiometer determines how fast the LED is blinking and it works by twisting the top of the potentiometer. As I twist the top the amount of volts it releases changes causing the LED to blink faster or slower.

Circuit #3 - RGB LED

This is the diagram for Circuit 3 that shows where the wires must go.

This demonstrates how the circuit works.

This is the main part of the sketch cause the light to change colors.

This is a video of the working RGB LED Arduino circuit.

Depending on the combination of colors and the brightness of each diode, different combinations can be created using this sketch.

Circuit #4 - Multiple LEDs

This is the diagram for circuit 4.

This is the unchanged sketch.

This explains how the circuit works.

This code uses a for () loop to change the pattern of when the LEDs light up. The video on the left is showing the ping pong code. When it is turned on it uses the loop to bounce the LED from one side to the other. The sketch for this is on the left. The for () loop is then used again in the marquee code. The video for this is on the right. The sketch for this is on the right.

This is the Ping Pong Sketch.

This is the Marque Sketch.

Circuit #5 - Push Buttons

This is the wiring schematic for circuit 5. It shows how the wires should be placed in order for the code to work the way it is suppose to.

In this video, you can see that when I push the buttons the LED lights up and when I am not pressing either then the LED goes off.

The way that the push button works with the Arduino, is how when the button is pushed, the voltage goes low, and the Arduino reads it and responds accordingly. The pull up resistor helps clean up the voltage and prevents false readings from the button.

This is the sketch for circuit 5, making the Arduino work.

Circuit #6 - Photo Resistor

This demonstrates where the wires need to go for the circuit to work correctly.

This explains how everything in the circuit works.

To the right is the sketch for circuit 6 and I manipulated the sketch by changing (0,1023) to (300,800). This resulted in the LED working better by turning on brighter and turning off darker.
