PLAY IN FULLSCREEN!!! At the start, to create the analogue wave, use the up and down keys to raise the amplitude and lower it. Then, put it in turbo mode (Shift+Press the green flag) while it makes calculations and then it will create the digital signal. This isn't very accurate as it only takes samples every 20 pixels because the wave would be too small to see. I put a lot of work into this so please love and favourite!
For some reason it is glitchy ( I don't know why!!!) and doesn't work sometimes!!! If it doesn't draw the blue wave then restart it!
