Common Acronyms & terms used in Python & MicroPython

• REPL
  • Read, Evaluate, Print, Loop
  • "It's what you get when you type python from the command line and see three chevrons (>>>) prompting you to do some interactive Python programming."
• WebREPL
  • Browser-based REPL used to communicate with ESP8266/ESP32 boards via local Wifi
• microfs
  • tool that uses the USB serial connection for working with the filesystem in MicroPython
• PWM
  • Pulse Width Modulation
  • a way to make digital signals emulate analog, by rapidly turning on and off while also controlling the time the voltage is on or off
• duty cycle ratio
  • Because power is only applied [to digital devices] when the duty cycle is on, the average power delivered to the device is the duty cycle ratio multiplied by the "on" time.
