Zoltan Hudak / Mbed OS WebTimer

A remote timer, equipped with a scheduling Web interface, controls a "DigitalOut".

Dependencies:   Timezone NTPClient

WebTimer

The WebTimer is an Mbed device enabling to remotely control a DigitalOut. It has a "calendar-like" user interface to edit the schedule - a table you can click on (or tap on a touch-screen device).
The program was ported to Mbed from the Tuxgraphics site. Thank you Guido for sharing!

  • When starting, it will print it's IP address over the USB serial link to the terminal screen. However, you can set a different static IP address if you modify the code in the main.cpp.
  • To connect to the WebTimer, type the IP address into the web browser edit box and hit ENTER.
  • When a cell is green then the timer keeps it's output ON during that period of time. If a cell is not green it means the output is OFF.
  • To select or deselect multiple cells you can click (keep down the button) and move the mouse over more cells.
  • The smallest time interval on this 24h timer is 15minutes.
  • To save the changes type in the password and hit ENTER or click on the Save button.
  • The default password is "secret". But you can change it by editing the source code in main.cpp.
