C.K. builds a Warning Light LED Soldering Practice Kit from Gikfun

A fun solder practice kit from Gikfun. Uses a 555 timer and two 4017 counters/dividers to turn on and flash two arrows in different patterns. Lots of soldering to do, so very good practice. Not too hard, though the tight spacing on the arrows makes it a challenge but just go slowly. Another good kit from Gikfun. 0:0 start 0:10 intro 00:29 What’s in the bag 07:59 Build begins 24:08 demo Product link https://www.amazon.com/dp/B0BPWV3X4T?...
