Hi folks,
I’m moving on from my uno stand-alone. I need to design two neoprene sleeves that alert the wearer to timing. Around the wrist, one with a red LED one with a green.
They will be controlled by a waist unit that simply controls the frequency of red / green flashing, i.e. it has a pair of faster / slower buttons.
I’m a Physio not an engineer, if it takes a year to learn that’s OK. At this point I just need to buy the right three units.
So, a master and two Bluetooth slaves. Adafruit seem to do small stuff? Regards, Al.
-a thought. Better would be a key fob / tiny tv remote in the pocket with faster / slower buttons to control the two micro controllers. Al
