I use another circuit different from the ones we have seen in the course to amplify the signals, but the basic principle is the same. | I use another circuit different from the ones we have seen in the course to amplify the signals, but the basic principle is the same. The NPN transistor will help us to amplify the signal we get from the planet. A passive speaker will be attached to the breadboard, so this installment has no need to rely on the external speaker or to connect to a computer. In this way, you can carry your circuit anywhere and play with it right away. | ||

'''Step 1''' | |||
Connect all the components in the way as the picture above. | |||
'''Step 2''' | |||
Connect your plants on flowers to the circuit. | |||
Here is an example of mine. One side of the wire is attached to the flower and the other side is connected to the end of the stem. | Here is an example of mine. One side of the wire is attached to the flower and the other side is connected to the end of the stem. | ||

Upload the code to the arduino. | |||
Below is the code for Ardunio, so the circuit will actually work. The data from the plant will be used to change the frequency and the duration. In this way ,the buzzer is able to produce different sounds. | Below is the code for Ardunio, so the circuit will actually work.
