Prework assignments demonstrate the use of conductive stitching, the ability to utilize two forms of output, along with two forms of input in an integrative design.

Eric’s PreWork Project

Description: The RGB is always going to be blinking, but the speed is going to depend on the position of the Switch, also if the Switch is ON the Vibe Board is going to vibrate along with the White LED.

Whenever the user press the Button the Vibe Board will vibrate with the White LED and the cycle of colors is going to change between Red Green and Blue cycles and Yellow Cyan and Purple cycles.

Inputs:  A Switch and a Button.

Outputs: The RGB LED, a White LED and the Vibe Board.

Prework Project

Input: Light Sensor, Button

Output: LEDs, Buzzer, Vibration

Discription: My prework project is that the leds will blink at first, and whenever the highest led blinks the buzzer and vibration will  ring. Also, there is a light senser dealing with the leds, so, when you put the lights on, led will reacts to the light’s voltage and they will turn up.  Of course the button will going to stop everything!

LED Distance Graph

Description-  What I present before you is a simple2x4 LED bar graph that corresponds to the distance between a Sharp IR Digital  sensor and an object.  The range is between 0 and 10cm.  When you hit the fourth LED, the buzzer sounds indicating that is the maximum range.  There is a SPST switch that can be used to turn the buzzer on or off.  The resolution of the bar graph could easily be increased by simply adding more LEDs if you wanted more precise measurements

Inputs– Sharp IR distance sensor, SPST switch

Outputs– 8 Green LEDs, buzzer

Game with Blinking Lights and Cheesy, Badly Transcribed Uplifting Trance Melodies

My design implements a simple game with two sets of blinking LEDs. The LEDs on the left-hand side blink at a constant rate, while the ones on the right-hand side blink at a rate that is controlled using the illumination of the light sensor. Shining more light on the light sensor will make the LEDs on the right blink faster.

The objective of the game is to get both LEDs to blink in sync by shining the right amount of light on the light sensor.  Both sets of LEDs must also blink in phase; this can be achieved by pressing and holding the button, which will delay the blinking phase of the right-hand LEDs. Once the player has won the game, they are rewarded with a melody, played through the buzzer. The melody is accompanied by vibration and LEDs blinking in sync with the melody.

Inputs: button, light sensor

Outputs: 4 LEDs, buzzer, vibe

PreWork Project

Due: By the end of class 10/16

Your prework project should:

  • Demonstrate the use of conductive stitching
  • Show two forms of output
  • Show two form of input
  • Combine these items together for an integrated design

Make a post in the Prework category with the following format:

Description: What does your prework project do?

Inputs:  What inputs did you use?

Outputs: What outputs did you use?

Video: Create a video which demonstrates the complete functionality of project (i.e. shows all input/output interactions)


Task 1 Requirements

The goal of this task is to design a circuit which utilizes various lights (LEDs). Your circuit should be constructed with conductive thread. Describe your design choices and post of video of your circuit in action.
