In the previous lessons we have been working with some code that turns on multiple lamps with the press of a single switch. After a short time delay, the lamps are supposed to turn off one at a time, one every second until all of lamps are turned off. As you know during writing and testing, we have discovered a couple of problems with the code and that it’s not working quite as we expect. In this lesson we are going to continue working with that program and find out exactly what we need to do in order for the program to work as intended. Let’s open up the lesson and complete the program.
