My aim was to put different functions into one program, to challenge the Arduino board and to see how much you can do by only using Arduino programming.
I the video, you can observe three different functions.
1) movement - melody
The circuit is the same as the one of a push button. When the frog is taken away from a sitting position, the circuit is interrupted and an alarm will ring and an LED will be switched on as long as the frog is sitting again.
2) distance - melody
A ping sensor is monitoring the distance in front of it. Once the distance is at a certain value, a melody will start playing and an LED will be turned on.
2) light - led (bluring)
There is also a photo cell. This sensor measures the light intensity. When it is quite dark an LED will start glowing. If it is light, it will be turned off.
