How to construct a timing circuit for a LED lighting circuit.? Answered
I am new to electronics but a quick learner. I have a dark path that I want to illuminate for about 2 to 3 minutes using a commercial LED light. It is too far to run a 120V line, so I am hoping to use a 3 - Volt Lithium battery connected to a timer that will shut-off the light automatically. I cannot use a motion sensor as the path is lined with trees that would set it off during windy sessions.
I am hoping to be able to push a normally off button, have the LED bulb illuminate and, after I have walked past the darkened area (2 to 3 minutes) automatically turn off, I need two units, one at each end. Also, can I adapt the lighting system to solar power? I really don't want to replace batteries often.
Can anyone help me. I can solder, follow a diagram and instructions. I will enclose the unit and make it as maintenance free as possible. If my choice of battery power is wrong, please advise me on any improvements. If there is a commercial timer available please let me where I can buy it incase it's too much for me to build.
