Activity: Touch Based Piano

Our touch-based piano will work like this: when we touch a particular sensor, then Quarky will play a note. The note will be different for each sensor.

Sounds cool? Let’s get started then!

Let’s Code!

Alert: Make sure that your Quarky is connected to PictoBlox either using Bluetooth or USB.

Follow the steps below to transform Quarky into a melodious piano:

Let’s start with the first touch sensor.

1. Open PictoBlox and create a New File.
2. Select the coding environment as Block Coding.
3. Go to the Sensors palette and add a when () is touched block into the scripting area. The first sensor, T1, is set as the default option.
   
4. To play sound, go to Speaker palette and add play tone of note () with duration () block below the when () is touched block
   According to the script so far, Quarky will play the note C4 if T1 is touched. You can test the script by touching the T1 pin.
5. Repeat steps 1 and 2 for T2, T3, T4, and T5. All you have to do is change the sensor chosen in each when () is touched block and the note in each play tone of note () with duration () block.
6. Save the file with the name Fruits Based Piano.

Have fun playing your piano!
