Today was the fire fighting competition. My robot Chappie was able to place 3rd in the competition. Above is a video of Chappie finding the candle. This was after the competition was over because i had forgotten to record it during the competition.

Today I spent most of the day programming my square bot for this maze. I am using encoders, a sonar, and a light sensor as a basis for this challenge. I  have managed to reach the top right room only but have successfully located the candle if it were to be placed in there.

Today I spent most of the day running a line sensor for my square bot. Above is a video of my sqaurebot using the line sensor.

2/5/15

Today I spent the day remounting and running a sonar on my square bot. I had originally used 2 sonars but due to construction issues it was not working properly. Above is a video of my square bot using a sonar sensor.

2/4/15

Mounted some sensors for use on my square bot.

2/3/15

Today, I programmed the encoders in order to complete the course without relying on time.

1/29/15

Today, I installed encoders on my squarebot but only used time and motor power to complete this course.

First blink

New rewritten code with if/else statement

 Using button with LED and buzzer

 Powering a motor and adapting it with a thermistor.

1/13/15

Made circuit using a transistor and a few resistors.

Used finger to complete the circuit.

Measured the current in the circuit using two voltmeters.

1/08/15

Oscillating light sing relay and capacitor

Light switch using relay.

1/07/15

Used multimeter to measure voltage coming from wall plug.

Then, used multimeter to measure voltage from different batteries.

We then used the multimeter to measure the resistance of a few resistors and compared it to the known values.

Made circuits using LEDs and different resistors

Built a square bot

Circuit board with resistors soldered on

Our first task was to solder on some resistors on the board.

Soldered wires

Next, I cut off the end of an AC/DC adapter and solder on some other wires to the positive and negative ends of the adapter. I then used shrink wrap to prevent the wires from touching.

Bread board with LED and 100 ohm  resistor

Using the AC/DC adapter from before, I used it to power an LED on a bread board. However, a resistor must also be used in order to prevent the LED from blowing out.

Bread board with LED and 470 ohm resistor   

I then used a 470 ohm resistor in the circuit and observed that it light up less dimly.
