Circuit 1 - Blinking LED

Shown above is a reference image showing the completed circuit. Shown below is the schematic of the circuit.

Edited Code

This code allows for the LED to blink but only in a very fast way, and the flash is barely visible.

Original Code

In this code, the delay waits one second to flash the LED on for one second.

Circuit 2 - Potentiometer

Code

As you turn the potentiometer, the LED will flash at a faster rate.

Below is the schematic for the circuit.

Edited Code

As the potentiometer is turned, the LED flashes slower

A potentiometer works by increasing or decreasing values. In this case, the potentiometer is decreasing the amount of time between blinks of the LED as it it turned.

Above is a schematic of the circuit

Orginal code

Lights turn off in opposite direction of turning on

Circuit 5 - Push Buttons

Above is a diagram of the circuit and the schematic.

This is the code that dictates the state of the LED

Circuit 6 - Photo Resistor

Above is a diagram of the circuit

To the left is the autotune code, and to the right is the manual tune. The auto tune is more precise, and will fully turn off when dark, but will turn the LED off when in partial darkness. The manual tune is more accurate in terms of all light and all dark, but in between those it is very jumpy, and will rapidly change brightness.

Circuit 7 - Temperature Sensor

This snippet of code is what causes an LED to light up when the recorded temperature goes above 72 degrees Farenheit.

Above is a diagram of the completed circuit.

Shown is a video of the circuit working with a LED that will light up when the temperature is above 73 degrees Fahrenheit.

Circuit 8 - A Single Servo

Video shown is of the edited version of the code, as shown in the picture.

To the left is a diagram of the completed circuit.

Below is a portion of code correlating to the frequency and angle of turning.

Circuit 9 - Buzzer

The diagram to the left is what the completed circuit would look like. Below is a segment of code involved in the playing of sound, and to the right is a video of the buzzer playing the classic Nokia ringtone.

Circuit 10 - Spinning a Motor

Shown above is the small bit of code controlling acceleration once it has been defined.

Below is the code in action, but to make it more interesting, the part of the code making the motor stop was deleted, so it decelerates to zero, then immediatly accelerates to full.
