Arduino Ne555 Piano

In this instructable i hope to be able to show you how to make a simple toy piano using a 555 timer ic and a few basic components, there isnt much code involved so its pretty beginner friendly, you can also make a test circuit in tinkercad when following the steps if you want to use different kind of resistors

NE 555 timer ic

breadboard
Arduino
Jumper cables

Push buttons
resistors

To make everything a bit more organized when adding the 555timer and timer, i try to to use the markings on the board, placed the 555 timer in between row E and F, with pins 1-4 going from column 48-51 and the capacitor in the same column of 48 and 49 connecting to pin 1 and 2 of 555 timer

the first connections ill make, is ground and VCC, pin 1 is ground and is on column 48 and pin 8 also on coloum 48 is vcc, then i try to bridge a connection from pin 2 of timer to pin 6 on the ic

for the piezo we have to keep in mind of where ground and power is, so when found out which is which, i had ground connect to the ground rail and power connect to pin 3 of the icc

this step pretty easy, we only need to add a 220 ohm resistor from the power rail connecting in to pin 7 and a jumper going from power rail to pin 4

the buttons can be placed how close or how far away u want, as long they are all on the same row of between E and F

ON row E u would wanna connect pin 2 of the icc to the bottom right leg of the button, when connecting the rest of the buttons keep in mind to skip one leg so that all the connections are in the bottom left leg and the jumpers are overlapping, in some way

this step is just a continuation of step 6, u want to bridge a connection from pin 7 on row F collum 49 to a resistor connecting to a button, but instead of using the left leg we're gonna be using the upper right legs of the button

like in step 6 we do same thing butt instead with jumpers different kind of resistors ranging from any range, we have the connections overlapping every upper right leg
