Flight activated LED's

[saam12]

hello i need someone to help me how to design acircuit
the project is to build a circuit with 3 leds nd the idea is when the glider
start to fly the light turn on and when it land swithced off

someone told me to use LDR

any one can help me with many thanks

It all depends on the size of the glider.

You could detect load on the wing and use that to turn on the lights, or perhaps have some flap held closed by aerodynamic forces (that will not be there when the glider is stopped)

Presuming the glider lands right way up, you could mount an LDR under it to detect when it goes dark (but then the lights would only work in the day). Also presuming it lands right side up, you could have a panel on the bottom of the glider that detects the weight of the glider (via a microswitch) -- kind of like a weight-on-wheels switch in large aircraft.

i really dont know about any sensors which can detect flying

but if i were you , i would use a mike at the front , so that some sort of noise at the front of the glider when flying, may trigger the led circit
