D-DAY!

The video title "LOL" should be more than sufficient to explain what happened this dread day. 

DAY 15! LAST DAY BEFORE COMPETITION!

The pressure was on to complete the robot and....

But here's the gist of our program taken from our power-point

and here is the code up until the first room.

Day 14!

TESTS TESTS AND MORE TESTS

MORE TESTING!

Day 13

Day 12 (Wed. Jan 29)

Day 11 (Tues Jan 28)

A video of our robot running through a labyrinth on encoders.

This is a GIF of our line sensor turning on an LED through Arduino.

Day 10 (Thurs Jan. 23)

A completed Arduino shield with a reset button and slots for Motors, Sensors, and Analog

On the flip-side you can see the soldering of the Arduino Shield as well as the conductive tracks.

And finally we added our encoders to our Vex bot!

Day 9 (Wed. Jan 22)

Short video of cookie monster being micro controlled to move back and forth to the rhythm of Mario, after he has had his back piece put back on

Cookie Monster code to make him move both forward and backward

Mario Theme song to make cookie monster dance

Day 8 (Tues. Jan 21)

Cookie monster moving in both directions using a bread board (with a h-bridge)

A H-bridge for my bidirectional motor.

Schematic for the H-bridge

Day 7

a torn apart micro-controlled cookie monster slowly ticking down. 

This is a micro controller controlling a mini lamp by use of delays

Note: the transistor amplifies the input current, so using a larger resistor will dim the light

Day 6

A push-button LED controlling when the light goes on and off.

My code for LDR controlled LED's.

A Picture of my previously mentioned LDR controlled LED's.

Day 5

An Arduino Uno being used as a microcontroller.

Arduino creating an LED Flashing Band.

A video of Arduino using a counter to speed up the LED.

Cookie Monster (Thursday Jan. 23)

COOKIEMONSTER

The Cookie Monster was really sad after going to rehab for his addiction to cookies. Much like all addicts cookie monster is freaking out because he cannot eat anymore cookies. It should also be noted that his fascination for Mario is so immense and deep rooted that you can hear their theme-song coming from his head!

Top: This is a H-Bridge, which allows us to move bidirectionally using pins 5(Direction) and 4(Motor).
Middle: Speaker connected to pin 8.
Bottom: A button which dictates when he can move.

Day 4

A picture of a completed remote controlled vex box bot.

A push-button controlling when the current touches the base of the transistor and when the LED turns on.

This is a video of how current is passing through my finger to the base of the transistor, allowing the LED to turn on.

Day 3

Using two Slide Switches to control an LED.

A push-button controlled relay which relies on a single-pole double-throw, to allow the LED's to flicker back and forth.

This push-button relay control works in a similar manner except now the button controls the throw, not when ground makes a connection. We also innovated a capacitor to allow the relay to oscillate and the LED's to flash.

The beginnings of my square-bot.

Day 2

A Picture of a few things we measure the voltage of.

This is a Light Dependent Resistor (LDR) meaning its ohms change with light and darkness.

A Breadboard with three lights each with a different resistor (100 ohms, 1,000 ohms and 10,000 ohms)

This is a video of 100 ohm resistor between an LED and potentiometer.

Day 1

This is a picture of my first time soldering. First we used flux to remove any oxidation. After soldering and clipping the wires we used isopropyl alcohol to clean the reaming flux off the board.

A picture of my components attached to the board.

Next, we practiced soldering wires. First we removed the insulation off the wire then carefully put the wires side by side to solder them. Finally we added shrink tubing to properly insulate  the joint.
