How would you make both LEDS work when you press the switch?

How would you make both LEDS work alternatively (not at the same time) when you press the switch?

For this project you will use a SWITCH, a LED and a SERVO. Tick all the components you will need:

You want to make the LED work when the value that gives the light sensor is LESS than 400. Otherwise, the LED must turn off.

You want to make the LED1 work when the value that gives the light sensor is LESS than 400 and LED2 when is LESS than 200. Otherwise, both LED and LED2 must turn off.

You want to make the zumbador play the "Do", "Re" and "Fa" notes (in this order) when switch is pressed. Otherwise, if the switch isn't pressed, it must turn off.

For this project you will use a SWITCH, a ZUMBADOR and a SERVO. Tick all the components you will need:

You want to make the zumbador play the "Do" note when switch1 is pressed. If you press switch2, the zumbador plays the "Re" note. Then, if none of them are pressed, the zumbador stops.

You want to make the LED work when the value that gives the light sensor is LESS than 500. If the value is less than 250, the ZUMBADOR must play the "Mi" note.

For this project you will use a LIGHT SENSOR, a LED and a ZUMBADOR. Tick all the components you will need:

You want to make the ZUMBADOR play the "Sol" note when the switch is pressed for just 1 SECOND. How would you do it?

For this project you will use a POTENCIÓMETRO, a ZUMBADOR and a LED. Tick all the components you will need:

You want to make your servo spin LEFT when switch1 is pressed. Also, you want to make your servo spin RIGHT when switch2 is pressed.
