Pallavi Murthy
Hi I am Pallavi Murthy and I am a going to the seventh grade. My morning class is a computing course. In my computing course, I have become familiar with Scratch and Processing. In Processing, I have programmed a monster. In scratch I have experimented with the different types of blocks and have created a quiz. I have learned a lot about programming and how I can use programming.
The monster I created on Processing, has two animated parts. The first animated part was that I could make the monsters pupils look at the mouse. If you moved the mouse, the pupils would move. It was difficult to make the pupils stay in the eyeball, but I finally got it. The second animated part was that if you clicked the mouse, the monster would change its color to a shade of gray.
In Scratch,I created a quiz about my favorite books. To make the quiz, I used techniques from the tic-tac toe game that I created earlier. My quiz consists of five questions. I created three variables: ” right”,” wrong”, and “questions” . The variable “right” increased by one each time you answered a question correctly.The variable wrong increased by one each time you answered a question incorrectly. The variable questions increased by one as you progressed through the quiz.
In my afternoon class are working on using the Arduino .So far I learned about Ohm’s Law, resistors, and different functions for programming the Arduino. I learned what a microprocessor does: takes inputs, does calculations, and controls outputs. We used potentiometers, buttons, resistors, and LEDs. We also used a seven segment display and a sensor. The first sketch that I created on the Arduino made the LEDs blink on and off.
Right now, I am building an ultrasonic range finder. An ultrasonic range finder sends out ultrasonic waves that bounces back from an object and uses the delay time, to find the distance from the object. I like how flexible the project is. You can add a button, or do what ever you want to the program and the circuit. Here is the url for my code: http://tny.cz/aed7fe56
frI also built a sound reactive lights circuit. Whenever music played from the speaker, the six LEDs lit up and danced to the music. For this circuit , I used two mini green breadboards connected to one another. It required a lot wires because the mini breadboards do not have a blue and red row.If I had done the project on a regular breadboard, my circuit would have been cleaner.
