So how about using a PIR sensor or an RCWL- 0516 sensor with a 5v trigger inbound2391766375315958612.jpgrelay to work an LED and musical movement driven by a motor?

Motion detector would set the musical movements and LED off. Sadly my 5v timer relay that I have has a constant 4.70v at its TRIG pin out. I was hoping to place my PIN OUT of 3.3v from my sensor onto the relay TRIG pin.

My 5v timer relay has a small black button and when its pressed it will activate the LED and musical movement for 10 seconds. I can adjust the timer with it onboard POT.

Basically I want the motion sensors to activate the relay NOT by me pressing a button.

Any ideas and feedback is greatly appreciated. I am.at the end of my tether with this project.

I never thought that a musical box motion sensor build would be such a headache for me.

hi T,
Depending upon the type of PIR you buy, most have a variable ON time, at least 10Secs.

Thank you for you input.

As much as I like the PIRs I have a love for the RCWL- 0516 sensors BUT the run time on this isn't long unless your willing to put on an SND capacitor to give it a runtime of 10secs.
