I want my program to be : when I enter '3' key to from the main menu selection > 'N' key to return back to the main menu selection.
But now It state "the expected an indented block" at
def Menu():
This is my full coding :
import RPi.GPIO as GPIO
import Slush
import math
import time
import sys
from inputs import get_key
from time import sleep
b = Slush.sBoard()
m = [Slush.Motor(0), Slush.Motor(1), Slush.Motor(2), Slush.Motor(3)]
m[0].setMaxSpeed(150)
m[1].setMaxSpeed(150)
m[2].setMaxSpeed(250)
m[3].setMaxSpeed(150)
m[0].setCurrent(150, 150, 150, 150)
m[1].setCurrent(100, 100, 100, 100)
m[2].setCurrent(150, 150, 150, 150)
m[3].setCurrent(100, 100, 100, 100)
GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)
pwm = GPIO.PWM(18, 50)
pwm.start(0)
GPIO.output(18, 1)
def Menu():
print("Please Enter Number From List Below:")
print("1: Start Program")
print("2: Control Manually")
print("3: Exit Program")
inputkey = int(input("Enter a number & Press Enter:"))
#START PROGRAM
if inputkey == 1:
print("Press Home Key To Start Program")

for event in events:

This is how I want my program to work. FLOW CHART : enter image description here
You have missed indentation in the def Menu. Please try the following code, since I don't know you exact logic, so the program might not work as per your need, but you will get a fair idea on the logic.
