QUESTION
Open

am a beginner and came across this project.
i wanna build an analog 2-axis joystick and interface it with a 3*3 led matrix to display the led position. once an led starts glowing, it should glow indefinitely. also wanna draw a password pattern which is stored already using joystick wich should be verified and if it’s valid, a green led should glow else red should glow . max time for drawing pattern is 10 seconds
Problems i am facing

  1. dunno how to make an analog 2 axis joystick
  2. dunno how to store a pattern which can be verified
