As delivered, the TES Sketch supports four Magic Commands. You can change, add, or delete Magic Commands since you have the source code.

The TES Shield has three LEDs which normally act as a small bargraph to display the signal strength of the received Lionel signal. These LEDs can also be ‘rippled’ to present a dramatic indication of successful communication with the TES.

The predefined Magic Commands are:

• Bargraph on/off
• Ripple on/off
• Clear recent signal strength history
• Save recent signal strength history to EEPROM

See the TES User Manual for complete details.
