For the past several weeks we’ve looked at blinky LEDs, 555 timers, and resistors. This week it’s time to put it all together into an application. A YouTube subscriber suggested the project as follows:
How would you go about having an led blink twice, then a different one blink twice, then back to the original one, and repeat; similar to a navigational light system on an airplane wing?
The stipulation was that the circuit needed to be built from a 555 timer. Takes some time to think about the problem. Maybe re-watch some of the other videos. When you’re ready continue to the answer below.
