Phil aka “sinking” shared a tech demo for an Ultimate GPS clock project running on a Trinket Pro.
Runs off a Trinket Pro, Ultimate GPS module and the two 24-channel PWM drivers. GPS digital clock test run. Note that dot matrix display is not active yet. Currently configured to show last few seconds before rollover of the minute, much like the beeps on the radio…
Clock logic is built on Arduino platform with LED chains being driven by Adafruit 24-channel PWM modules.
Featured Adafruit Product!
Adafruit Pro Trinket – 5V 16MHz: Trinket’s got a big sister in town – the Pro Trinket 5V! Pro Trinket combines everything you love about Trinket with the familiarity of the common core Arduino chip, the ATmega328. It’s like an Arduino Pro Mini with more pins and USB tossed in, so delicious. (read more)
