Building TZXDuino

To load programs on the AZ Spectrum you need a cassette player…or so I thought.


Came across TZXDuino which lets you play files from the SD card using an Arduino and a amplifier.


Rigged this up in a morning and it works beautifully. I updated the code to use a LCD 16×2 without I2C.

Its fairly easy to build and uses:

  • Arduino Mini Pro
  • SD Card
  • LCD 16×2
  • 5 x buttons
  • LM386 amplifier (Circuit from StackExchange)
