**HW21: Keyboard Control of a Motor**Review the earlier lesson on getting serial input from the keyboard. Next, set up a menu screen similar to the one shown in the image, but using the options of Stop, Start, Increase Speed, and Decrease Speed. Have the user's keyboard input control the DC motor.EC, 5 pts, if you use BlueTooth to communicate with the Arduino from your computer or phone.---**Explanation of the Serial Monitor:**The image shows an Arduino serial monitor with the following options displayed for controlling a motor:- **1. STOP**: Stops the motor.- **2. FORWARD**: Moves the motor forward.- **3. REVERSE**: Reverses the motor direction.- **4. READ CURRENT**: Reads the current status of the motor.- **+. INCREASE SPEED**: Increases the motor's speed.- **-. DECREASE SPEED**: Decreases the motor's speed.The serial monitor allows for interactive input, where numbers corresponding to actions are used to control the motor through the Arduino. The communication settings at the bottom (e.g., baud rate) facilitate accurate data transmission.

Executable Python code: t = int(input())for i in range(t): n = int(input()) l = list(map(int, input().split())) c = 0 for j in range(n): if l[j] % 2 != 0: c = 1 break if c == 1: print(0) else: s = 123456789123456789 for k in range(n): ans = 0 while l[k] % 2 != 1: l[k] = l[k] // 2 ans += 1 if ans < s: s = ans print(s) Code Screenshot along with Output:Executable Python code: t = int(input())for i in range(t): n = int(input()) l = list(map(int, input().split())) c = 0 for j in range(n): if l[j] % 2 != 0: c = 1 break if c == 1: print(0) else: s = 123456789123456789 for k in range(n): ans = 0 while l[k] % 2 != 1: l[k] = l[k] // 2 ans += 1 if ans < s: s = ans print(s) Code Screenshot along with Output:
