Your video demonstration should show you engaging the pushbutton to turn the light on....and the light stays on as long as the pushbutton is depressed; releasing the pushbutton shuts off the LED. This is called maintain contact. You can do this project without any software (sketch) - simply connect a jumper wire from +5V power supply on the Arduino Board to the breadboard; then connect a PushButton and an LED in series with a jumper wire connected to Ground (-) on the Arduino Board.
Read Boxall (pg 63) for which shows how the PB works. Study the hardware photo (below)....this is the one Arduino project where it is OK to follow the photo and video for your wiring guidance. For future scripted projects....follow the schematics!
Create a single post for this project on your student web pages (you will make a separate post for every project), Reflect on what was easy, what was difficult, and tell me something you did not know but learned from this project. Include a photo of your hardware and a 10-20 second video demonstrating the intended application
Pushbutton - Maintain Contact (no sketch required)
Pushbutton - Maintain Contact
Note that power to the PB is on the right hand side, and the light will only stay on with the PB depressed when the jumper wire is on the left hand side (opposite the power source)
