$2$vj$.$ PLEASE SOLVE ALL TASKS. THANKS.

For each connection, you MUST draw the scheme according to the picture below by hand on paper and attach a picture of the scheme for each task. $($ARDUIO UNO$)$

a$).$ Draw an electrical diagram of the Arduino Uno microcontroller, on which one button and one LED are connected.

b$)$ Write a program that will print the state of the keys on the serial monitor every two seconds.

c$)$ It is necessary to program the microcontroller so that the LED lights up while the button is pressed. each task solution must contain a drawn diagram $($do not need to be connected to the fritz$)$ and program code with comments.

d$)$ It is necessary to program the microcontroller so that the LED lights up at the first key press, and the LED turns off at the second key press. each task solution must contain a drawn diagram $($do not need to be connected to the fritz$)$ and program code with comments.

e$)$ It is necessary to connect two LEDs and a button to the microcontroller. Program the microcontroller so that when the button is pressed, the first LED should light up$,$ and when the button is released, the second LED should light up$.$ Add the LED to the schematic. each task solution must contain a drawn diagram $($do not need to be connected to the fritz$)$ and program code with comments.

f$)$ Connect the LED and two buttons to the microcontroller. Write a program that will turn on the LED when the first key is pressed and turn off the LED when the second key is pressed. each task solution must contain a drawn diagram $($do not need to be connected to the fritz$)$ and program code with comments.
