Lane Ready Lights
Description
Need a way to signal people waiting in line when the next lane/register is available
Flashing light
Possibly a buzzer or sound?
Easy to press momentary pushbutton
Way to clamp down to table/desk
Tall for best visibility
To do list
Get it working on 5V USB instead of 9V battery
Maximize brightness
Flash red for help and green for next
Bend some white acrylic for the light fixture
Future improvements
Make actual PCBs, not just wires on perforated proto boards
Wire USB power cord directly to PCB, no use for jack
