Description: 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! bit.ly/3k8BM6j Watch the previous episode, "How Electromechanical Relays Work" - bit.ly/37dbe0p Engage with the element14 presents team on the element14 Community - suggest builds, find project files and behind the scenes video: bit.ly/3tmdewv Visit the element14 Community for more great activities and free hardware: bit.ly/3q6YMpu Tech Spotlights: bit.ly/3qPrDhM RoadTest and Reviews: bit.ly/3pV5Bux Project14: bit.ly/31wbnJY #0:00 Welcome to DC to Daylight #1:07 Components #2:09 Schematic #6:28 Putting it Together #7:28 Test and Troubleshooting #10:15 Give Your Feedback #electromechanical #transistor #555timer
