Based on the wired Tilt Sensing Bracelet, this version uses Xbee Direct (Xbee-Xbee) communication connection to send the digital data from the tilt sensing bracelet to a feedback bracelet which has an LED display. LEDs light up according to where the tilt sensor is making contact.
The bracelets are communicating wirelessly through Xbees with I/O Line Passing mode. The detail setting (AT command) for this is posted here
The schematic for this bracelet is following.
