This is my first post so HELLO!
I took electronics at school 4 years ago so have some knollege of electronics but im very rusty.
I have just taken up Airsoft and would like to make some devices for some of the games. The first device I would like to make is a wireless device to alert me when someone trips a wireless sensor.
There are to to parts to this project:
Part 1.
A small display that can be attatched to my wrist to silently alert me to the sensor is tripped. I was thinkig LEDs would be the best option. (I am thinking 4 LEDS for 4 sensors)
Part 2.
I would like 4 motion sensors. Very small. They just need to wirelessly activate the LEDs on my wrist when someone moves past the sensor. They will be used inside and outside.
I would like a good range for these but have no idea on what I can get away with! 500 meters including inside a stone building would be great.
Any help you could give me on this would be wicked!
Thank you for your time!
