Counting Binary with Six LEDs

This project is very similar to the project “Marching” LEDS. However, we will use the six LEDs to output a six bit binary number instead of “Marching.”

Making an LED "Breathe"

This project discusses pulse-width modulation (PWM) and how to use it to make an LED “breathe.” The term “breathing” is used to describe how we will make the LED repeatedly grow brighter (until it is completely on) and dimmer (until it is completely off).

In this project, we will use PWM to control the color of a tricolor LED.

This project will build upon the Breathing LED with Pulse-Width Modulation project, now introducing an element of user input by allowing manual control over the brightness of the LED. To accomplish this, we will introduce a new component called a potentiometer.

This project implements a servo control circuit that will use the chipKIT™ board to read button presses and move the position of a servo's motor shaft accordingly.

For this project, we will improve upon the design from the Servo Control with Servo Library project by replacing the pushbuttons with a single potentiometer (a variable resistor).

For this project, we will be building a control system that allows a servo to align itself to the direction of light coming from a flashlight. To do this we will use light sensitive resistors to detect the direction the light is coming from.

In this project, we will demonstrate how to use a relay to control a circuit. A relay is an electrically operated switch that is typically used to control high power circuits.

In this project, we will be generating sound using a piezoelectric buzzer. We will initially explore how to generate different frequencies by cycling a digital pin from HIGH to LOW at different rates. We will then examine some of the fundamentals of music theory and how they can help us play music with our buzzer.

In this project, a button is again used to control an on-board LED, but things get a bit more complicated. Instead of simply having the state of the LED correspond to the state of the button, in this project the LED's state will toggle every time the button is pushed.

Relay Controlled Camera Flash

In this design challenge we will use a relay to control the flash circuit found in a disposable camera. Specifically we will modify the circuit built in the relay controlled LEDs project.

For this project, we will be expanding on the concepts introduced in the Creating Music With a Piezo Element project by creating a sine wave generator. Instead of rapidly toggling a digital pin high or low to generate an output signal, we will be using an external digital to analog converter (DAC for short) for more control over the signal. Additionally, we will be incorporating potentiometers for volume and frequency control of the sine wave.
