The play tone block allows a range letter note tones from C to B5. Songs are played using sequences notes. Like the beginning of a birthday song (C, C, D, C, F, E).
Challenge: Create samples of longer music to play for each button instead of the single tone Tip*: Search for “ABC music notation” or “Easy Music Notes” + the name of a song
The forever loop really does run forever. The forever loop is useful when there is a need to continually check for an event or use a changing value in code.
Micro:bit Vs Raspberry Pi For Kids

255 is the maximum light input reading, try numbers smaller than 255 Find a value that allows the graph to show 1 – 5 bars
Frequency measured in Hz which are cycles per second or vibrations per second A healthy human ear can detect frequencies in the range of 20Hz to 20, 000Hz. The micro:bit + headphones reliably produce detectable output ~50Hz – 6, 000Hz.
Are You In Tune?
Set tone, using Math multiplication block that multiplies light level input by 25 or experiment with multipliers larger and smaller than 25
The micro:bit contains an accelerometer sensor that is able to measure forces applied to the board. On earth, we are subject to the gravity force which pulls us to the ground!
When the micro:bit is flat on a table, with the screen pointing up, the gravity force is aligned with the Z axis of the micro:bit.

If you tilt it up and down, the force will align with the Y axis – this is how we can detect tilting!!! If the force along Y grows, the micro:bit is tilting more and more vertically!
Create the code that measures the change in the Y axis acceleration as a graph on the LEDsDowload the code to the micro:bit Test the movements that move the graph from 1 to 5 bars on the LEDs
Create the code that Maps Y axis acceleration as tempo Download the code to the micro:bit on the guitar Test the movements that speed and slow the tempo

Combine the code above with the light sensor tone control code from the previous activityDownload the code to the micro:bit on the guitar Now play the guitar adjusting tone and tempo using the light sensor and accelerometer!
Hold the micro:bit touching The GND pin with one hand with the other hand alternately touch the 0, 1 and 2 pins. The electric signal traveled from pins, between your hands to GND and the micro:bit detected the electric signal!

Turn the guitar ON and OFF with a pin press on the connected foil by touching both pieces of foil at the same time to connect the switches.We’ve all heard of the game, Guitar Hero, whereby players use a guitar-shaped game controller to simulate an actual guitar. In this instructable, we’ll teach you how to make your very own customisable guitar controller paired with micro:bit! You’ll never have a silent moment again in the house! So let’s get started!
Bend the side straps on the edge of one guitar body, and glue them together. Once done, glue the other guitar shape piece on top to get a full bodied cardboard guitar frame.
Next, we will make the neck of the guitar. Cut out 2 straps of the neck piece at dimension of 28x4cm. Put 3 pairs of wooden chopsticks in between the 2 straps, and glue them together. This is to provide a strong support for the guitar neck.

Cut out the body top cover of 5x3.5 cm, and cut a slit of 4x1.5cm in the centre to slot in the neck later.
After slotting in the neck portion, you may apply glue for added reinforcement. Product should look like the picture on the right.
Cut 2 identical pieces from the cardboard to form a guitar head, and glue them together. Insert the head into the guitar neck, and glue the connecting edge between the neck and head. You’ll now have a finished guitar design. Start decorating it with your art materials!
Micro:bit At Home
In this step, we will code the Micro:bit in Block Editor. You can access the block editor from the captions below. In this project, we will program the guitar to play some pre-programed melodies by pressing onto buttons and changing its pitch by tilting the guitar in certain angles.
Next, we can program the Micro:bit to play different melodies when pressing either Button A or B. We’ve programmed button A to play “We Will Rock You” when pressed while button B plays “Let It Go” (Frozen).The images on the right will show the codes required for both button A and B. Feel free to create your own song if you wish to!
Let’s make a mode whereby Micro:bit produces a sound when tilting. This mode will be triggered by pressing on Pin1. Rename a variable “pin1” to read the analog signal from Pin1, and this variable will decide if Pin1 is pressed.
Make Music On Your Bbc Micro:bit
After all the coding is done, we can use the simulator on the left to try out all the functions we have programmed. Plug in the micro:bit to your computer, download the script and copy it onto the micro:bit. Copy the downloaded script to your micro:bit drive. The downloaded script ends with a .hex extension.
The link for the 3D design will be in the captions below. After you download the model, use your 3D printer to print them out.The final Micro:bit cover should look like the image on the right.
Place the programmed Micro:bit into the printed cover, and use a pair of screw and nut to secure the cover. Connect the Micro:bit with batteries. Take 2 alligator clip wires to connect Micro:bit with the audio cable of mini speaker. You can refer to the image on the right if you’re unsure of the wiring.
How To Make A Guitar With A Micro:bit ?
In order to press Pin1 easily, we can extend Pin1 out to the guitar neck. Use a long strap of aluminium foil, and tape in from the guitar to the neck.
Paste conductive copper tape on the top of the aluminium foil, paste one end to Pin1 on Micro:bit. In this way, you press Pin1 by pressing the copper tape on the guitar neck.
Andddd you’re done! You now have your very own Micro:bit Air Guitar. Go forth and test the capabilities of it! Have fun!
