Make your own DIY oscilloscope for £4 - Raspberry Pi PICO Project

Make your own DIY oscilloscope for £4 Amazon sell full kits if you are starting from nil: UK: https://amzn.to/3OxvpHn USA: https://amzn.to/39Nvc3u Admittedly that might cost you more than the $5 that route, but you will have a nice little setup for experiments! Python Source Code is included here, but for performance, switch to the Arduino stack: from machine import Pin, I2C, PWM from ssd1306 import SSD1306_I2C import utime #lets go! button = Pin(10, Pin.IN, Pin.PULL_DOWN) pwm = PWM(Pin(12)) pwm.freq(100) #1k pwm.duty_u16(32767) adc_read = machine.ADC(26) #A read takes 2us therefore 500ks/s! i2c = I2C(0,sda=Pin(0),scl=Pin(1),freq=40000) oled = SSD1306_I2C(128,32,i2c) oled.fill(0) oled.text("Ready!",0,0) oled.show() #update the screen! coefficient = 3.35 / 32767 while True: reading = adc_read.read_u16() calcvoltage = reading * coefficient print("V", calcvoltage) if button.value(): screenstuff = str(calcvoltage) oled.fill(0) oled.text(screenstuff,0,0) oled.show() #update the screen! utime.sleep(0.01) Come chat with me on discord   / discord   See my recommendations on Amazon: https://www.amazon.co.uk/shop/backoff...
