Button LED circuit
What you need:
- 1 Red LED
- 1 Button
- 2 330 Ohm resistors
- 7 cables
Connect the components according to the following diagram:
We are going to program the Arduino to make the LED on when we press the button. Open the Arduino software, and edit the code to the following:
Finally, press the arrow button at the top to run the program on your Arduino (you'll have to save the project somewhere on the computer first though!). Press the button and see what happens!
Evaluation Questions:
- How do you think the button works, in terms of electric current?
- How would you make the LED toggle between ON and OFF when pressing the button?
