Why it is necessary to connect cathode of rgb led to the push button?
In the video (9:55), when each time the push button is pressed they get a single color but as per the program they should get the led sequence for every push... someone explain this
I have used 220k ohms register, when I am connecting the longest pin of the tri-color LED to GND it is not working, but when I am shifting the pin to 3.3v its works(RGB Emitted), and when the pin is shifted to any other pin of the power row, 4 types of light are emitted by the led (white, yellow, turkeys blue, pink ) not RGB. where I am going wrong. please Help
Push button program is not showing any output .My led keeps blinking whether the button is pressed or not.What to do now?
Tutorial 6: Arduino with Tricolor LED and Push-button - EnglishTime: 8:10The video has an explanation but I am not able to understand why we need to use register between pin no 4 and Anode pin of LED.
Wrong microcontroller found. Did you select the right board from the Tools > Board menu?
