The light has a series of spot and floor leds that pass there 2 different lenses and im able to vary the brightness of each spot/flood group to change the over all beam pattern… 10 times a second seem good, if i need it faster i will increase my estimated refresh rate.
Now a 1 more question.
How do i know when i have a “stale” speed reading and should start my 10hz “estimated” speed if tiny gps always returns a speed when i call it? Should i just wait for the first gps speed number change and then just start a counter based on millis() ?
