design circuit that controlles a wheel chair

[dudy]

what do u suggest please gus help i urgently need this

 

[plot]

I suggest using a microcontroller to receive inputs from the user... then the microcontroller could drive some FET's which would power the motors of the wheelchair or something similar.

What exactly do you need to control on the wheel chair?

 

[panic mode]

are you asking for pwm circuit to control motor speed or joystick control or what?

thanx for replying i want keypad or a joystick circuit located at the hand of the disappled person this circuit is connected to the motor located at the wheels to perform movement to the write or left up & down when the aproporite signal transfered to the motor

if you want it stupid simple you cod have a simple joystic that wod pres switches that switch the motors on of (a joystic becose if you wod push forwarn an left you wod create an short circuit)

ok check this out it would not make boring iwant a voice key circuit that saves my 2 voices in a memory and when i say my voice it compare between my voice and the 2 voices it had if one of the voices match it will give a signal to open ...... say adoor what do u think

I dont think those expensive voice recongison ICs wod do the trick.I never thoght of doidg that ether
