Here is the proyect, making a failsafe autonome Baby Cart
believe me my life is at risk here, im in high school studyng mechatronics so im still learning how to make some stuff but i know the basics the thing is an aunt wants me to make a baby cart for my newly born cousin that can be radiocontrolled or moved by the baby and stops automatically if there is a fall when the baby is in free roam mode.
Using a PIC for the proyect, the circuit uses 2 voltage lines, a main 5V supply is for powering the PIC controller, sensors, output relays, the logic circuit and the RC control (borrowed from a RC car), the secondary 12v power supply is used for the motors for the wheels and the motors on the deployable legs (for stopping the cart if the baby wants to go off a cliff and the sensors stop dettecting ground).
i want to connect 8 sensors but the pic only has 6 input ports and 2 are used for the RC control is it plausible to connect 2 sensors to each port while passing by the same "not" gate?
if the baby falls im going to be dead
