Arduino code

To build a lock system based on gender by voice authorization. The lock will open the door if the speaker was female. The voice frequency of male and female will be calculated by IQR method. The system contains Solenoid lock, electrit microphone and LCD. The system will works as follows: 1- LCD screen shows "Say a word" 2- The speaker will say word in microphone 3- LCD screen will show "Processing" 4- While processing, the voice frequency will be calculated. Female frequency= 165 TO 255 Hz , Male frequency = 85 to 180 Hz. 5- If the frequency of speaker didn't overlap between to ranges ( 165 to 180 ) , no need for to perform IQR and the result will show in LCD. If speaker is male the LCD will show " Male, access is denied" and the speaker will have 5 trials . Otherwise LCD will show"Female, access is granted" and the lock will open. 6- In case the speaker voice frequency located between 165 to 180 Hz, IQR should be used. 7- The IQR male is more than 0.07 and for female is equals or less than 0.07. Then the decision will be made. I attached the equipments and circuit and the IQR calculation method and the code for the circuit. The code should work with them and the code is attached in case to make a reference of it. I want the code today or tomorrow. The budget should be between 120$ to 150$
