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 an illustration for the completed circuit for circuit one.

This is the code for the working circuit, with a delay of 1000ms that can be manipulated to blink faster or slower.

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

Process

This is the manipulated code to make the LED blink faster.

This is a video of the manipulated circuit code, and the faster blinking LED.

Circuit #2 - Potentiometer

This is an image of the completed circuit for circuit 2.

This is the code for the circuit, which determines how fast the LED should blink based on the potentiometer.

This is a video of the dial of the potentiometer being turned. The LED's blinking speed changes as the dial is turned left and right.

Process

The potentiometer is also known as a variable resistor, and it works by changing the amount of voltage it releases which is from 0 to 5 depending on the location of the knob.

Circuit #3 - RGB LED

This is an image of the working circuit board for circuit #3.

This is the main part of the code.

Depending on the brightness of each diode, and the combinations of colors, many different color combinations can be used in a RGB LED.

This is the code function for circuit 3.

Process

Circuit #4 - Multiple LEDs

This is an image of the working circuit board for circuit #4.

This is circuit 4's code function.

This is the original code for the LEDs.

Process

This code includes a for() loop to change the order/pattern of the LEDs lighting up. When the ping pong code is turned on, it used this loop to bounce the light from one end to the other like seen in the video.

The for() loop is used again in this code function, the marquee code. When this is enabled, the lights move in a way that looks like a LED sign that you would see.

Circuit #5 - Push Buttons

This is an image of the working circuit board for circuit #5.

This is the code for circuit 5. When one button is being pressed, it turns the LED on and when both are pressed the LED is turned off.

This is a video of circuit 5 where the LED turns on and off according to the buttons I pushed.

This is circuit 5's code function.

Circuit #6 - Photo Resistor

This is an image of the working circuit board for circuit #6.

This is the code for circuit 6. We manipulated the code by changing the range of light level from its original range, (0, 1023), to (300, 800). This caused the LED to work better by turning on and off at brighter and darker ranges.

Process

This is a video of the autoTune() function. The pros of this is that it is automatic, and no code has to be manipulated, but the cons of this is that the brightness can't be adjusted to work better.

This is an image of the code function for autoTune().

This is a video of the manualTune() function. The pros of this is that you can change the range of brightness and darkness that it has, cons being that you have to manipulate the code yourself to see what range works best.
