Project to auto roll up a car window.
I would like to achieve the following functions using Arduino Uno.
Whenever UP SWITCH is pulled up, the window should roll up automatically regardless of whether the switch is still on hold or released.
As the window rise up, any resistance or object hindering on its way is encountered, the window rolling should be shut off instantly.
Any extra sensors like current sensor, etc., necessary would be always welcome.
All electric window actions in the UP direction should BE DEADMAN SWITCH operation.
Any sort of monitoring to prevent crushing an obstruction only makes for complexity and hence more to fail.
I know its from Wiki, but;
Power windows have come under some scrutiny after several fatal accidents in which children's necks have become trapped, leading to suffocation. Some designs place the switch in a location on a hand rest where it can be accidentally triggered by a child climbing to place his or her head out of the window. To prevent this, many vehicles feature a driver-controlled lockout switch, preventing rear-seat passengers (usually smaller children) from accidentally triggering the switches. This also prevents children from playing with them and pets riding with their heads out windows from activating the power window switch.
Starting with the 2008 model year, U.S. government regulations required automakers to install safety mechanisms to improve child safety. However, the rules do not prevent all potential injuries to a hand, finger, or even a child's head, if someone deliberately holds the switch when the window is closing. In 2009, the U.S. auto safety administration tentatively decided against requiring all cars to have automatic reversing power windows if they sense an obstruction while closing. Proposed requirements concern automatic ("one-touch up") window systems, but most vehicles with this feature already have automatic-reversing. The federal government made a written contract that all automakers should make the lever switches (as opposed to the rocker and toggle switches) standard on all new vehicles by 1 October 2010.

I wonder why?
