Greg Steiert / Mbed 2 deprecated ALS_Proximity_Demo

This demonstrates some of the capabilities of the MAX44000. It is written to work with the ARD2PMD adapter board and the MAX44000PMB1. It uses the standard Arduino pin names and will compile for most Arduino form-factor mbed boards.

Dependencies:   ard2pmod mbed

This demonstrates some of the capabilities of the MAX44000.

This is written to work with the ARD2PMD adapter board and the MAX44000PMB1. It uses the standard Arduino pin names and it will compile for most Arduino form-factor mbed boards.

Some boards use D13 for an LED signal, so this example uses the second row (row B, pins 7 through 12) of the Pmod connector.

  • LED1 toggles when something is first detected by the proximity sensor.
  • LED2 indicates when the Ambient Light Sensor reads grater than alsLim.
  • LED3 will stay on whenever something is detected by the proximity sensor and stay on for an additional 5s after it is no longer detected.

The following boards have been tested to work:

  • MAX32600MBED
  • FRDM-KL25Z
  • FRDM-K64F
  • Seeeduino Arch (LEDs inverted)
  • Seeeduino Arch Pro
  • ST Nucleo F401RE (only one LED, inverted)
