Using Relays to Make a Vegas Style Sign - DC to Daylight

In the previous episode, we looked at how to drive a relay from a lower power semiconductor device, using an NPN transistor as a buffer. In this episode, we'll put our knowledge to the test by using a 555 timer, a CD4017 decade counter, and some transistors and relays to make a Las Vegas style blinking sign. We unfortunately hit a little snag, due to the fact that lamps require significant current when turning on, ultimately leading to some quick troubleshooting. Let’s roll the dice and see if we can bring this sign to life! https://bit.ly/3k8BM6j
