I Made a THING with arduino

I call it “The cool but impracticable Wrist Device”

just thought id share since people at work seem to be amazed by it :stuck_out_tongue:


it has a toggle button that cycles through WATCH/FLIGH LIGHT/PULSE READER modes.

it has a variable resister knobs for LCD brightness as well as for contrast.

has a buzzer attached to pin 13 so when a heart beat is detected it beeps :stuck_out_tongue: powered by an arduino nano clone and a 9v battery.
