Hello. I am the children's ministry director at my church. I want to build a game timer tower. I have done a little with IC chips and pcb's but I want to start using programmable boards to do more. I have very little understanding on HOW it works, just good at putting in pieces and following directions.
I want to build a tower about 5' tall. I would like it to have 12 segments of LEDs. The Top row would be "Standby" or waiting mode. Push a button, and the lights would move consecutively down the tower until the last. It would then stay on the last for a set amount of time, then reset back to "Standby" until someone hits the button again.
I have the ARDUINO UNO board, a spst button, and LOTS of LEDs. What I don't have is the knowledge. Also, I only have 3 weeks to get this programed and built.
I have spent a couple of days reading through the forum and playground, and understand the "debounce" code, but was not sure if it is needed since pushing the button would start the sequence of set times.
I also wondered if a sketch could be written so that the towers default would be a fast top to bottom loop, then go to standby when the button is pushed once, then do the actual countdown on a second push (obviously need a debounce here), then pause for a set time, and go back to loop.
If anyone is able to help me with this, I would so appreciate it. I will be checking here hourly, but I can also be reached at 727-809-0926 or at email@example.com. Thank you.
