Output devices
This week I decided to start working on the code and board I will need for my final project.
I started to make a schema ,for my input I will use a motion sensor to detect wen the ball will stop moving.
for my output I will need a speaker,several leds and a small motor.

My first atempt was to conect the Arduino to a buzzer and conect it to a sensor (I don't have the motion sensor now, so I used a photocell sensor instead ).

I started with an Arduino code that will make a wavy sound as I play with the sensor

My second atempt was to conect the piezo sensor and a motor to the Arduino, and control the motor by the movment of the piezo sensor.

My theerd atempt was to conect all the components (piezo,speaker,and motor) to the Arduino , and control them the way I want.

After I finishet experamenting with the Arduino, I started to desing my board in eagle, you ken dawonlode the schematics/ board files if you want to add samthing or dawonlode thetrace/interior files.
Mill the board and solder the components on it.

I used sokets for the piezo sensor and motor and pin for the speaker .
I conected the FTDI and the AVR to the board and borend the botloder. then check the pin nombers.

And burn the code on the Attiny 44.

}

You ken dawonlode the Arduino files hare.
Check evrithing workes on your board and make modefection in the code if nesasery.

Success.
