G+_Cameron Skinner Posted April 19, 2015 Share Posted April 19, 2015 I would like to put LEDs on my X alien. I think I could connect them directly to the power distribution board. If I want to connect them using a switch on the transmitter what do i need? Link to comment Share on other sites More sharing options...
G+_Eddie Foy Posted April 19, 2015 Share Posted April 19, 2015 Switch on a xmitter will typically output a PWM (a pulse every 20MS of a duration) signal they are not a digital ON/OFF deal. Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 19, 2015 Author Share Posted April 19, 2015 Eddie Foy Thanks. I believe that I must need some sort of a relay that is controlled through PWM. Link to comment Share on other sites More sharing options...
G+_610GARAGE Posted April 19, 2015 Share Posted April 19, 2015 This is what you would need. http://www.ebay.com/itm/Turnigy-Receiver-Controlled-Switch-Relay-For-Airplane-Multirotor-Retract-light-/171572174036?_trksid=p2141725.m3641.l6368 Link to comment Share on other sites More sharing options...
G+_Quadflyingmedic Posted April 19, 2015 Share Posted April 19, 2015 Look on pololu.com they have rc controlled swithces there too. They are nice and compact Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 20, 2015 Share Posted April 20, 2015 On my quad with kk board I wired them to power through the NC contact of a relay. Then ran relay power and signal to the alarm output. That way lights are on and then blink fast when battery voltage hits threshold. Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 21, 2015 Author Share Posted April 21, 2015 DeWayne Shorts that sounds pretty cool but would the Turnigy relays have an NC contact or would I need a different type of relay? Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 21, 2015 Author Share Posted April 21, 2015 BTW thank you everyone for your comments so far they have been very helpful. Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 21, 2015 Share Posted April 21, 2015 I just got ones off Amazon like you would use on an arduino project. Less than $3 Arduino DC 5V Coil Relay Module for SCM Development/Home Appliance Control https://www.amazon.com/dp/B00EDMIXLO/ref=cm_sw_r_awd_5Eznvb18E7ZYM Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 21, 2015 Share Posted April 21, 2015 Used 4 of these. Very bright! https://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=57695 Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 21, 2015 Author Share Posted April 21, 2015 Now I have a lot to think about. Thank you very much for everybody's help. Link to comment Share on other sites More sharing options...
G+_Steve C Posted April 21, 2015 Share Posted April 21, 2015 DeWayne, I don't think that relay module will work with a PWM signal, looks like it's just a relay. I tried one of these 2CH Remote Controlled Electronic Switch Modules that's small and light and will work off the PWM output of the receiver. It will operate an LED light but only stays on for about 1 second. They don't say it anywhere in the auction but the module was intended to be used to fire the fuse on smoke bombs used in model airplanes when they need to release smoke and only stays on for long enough to do that. If someone could figure out a way to make it stay on as long as it is activated it would be perfect for this. http://www.ebay.com/itm/2CH-Output-Remote-Controller-Electronic-Switch-Module-TDF-Compatiblegi-/361092513194 Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 22, 2015 Share Posted April 22, 2015 Not sure what board he is using. If it has output for Buzzer for warning signal this will work. All pwm is is on/off to simulate a wave so it just depends on the "frequency". The led's in that link do run on 12volts. Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 22, 2015 Author Share Posted April 22, 2015 I am running a KK 2.1. 5 so I think what you are saying should work well. Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 23, 2015 Share Posted April 23, 2015 Those led's are nice and bright. If you have an open field it's really cool at night. I found night flying with them it's actually easier to keep orientation than I daylight. Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 23, 2015 Author Share Posted April 23, 2015 Actually I have a 1 meter strip of LEDs that I was going to break into chunks and attach them to the two rear legs in order to keep the orientation correct and I was going to drive them using the relay. These are supposed to work using 12 volts so it should be similar to your connection. eventually I may put those on a receiver controlled line and put the corn cob lights the way that you did from the relay.

G+_Cameron Skinner Posted April 23, 2015 Author Share Posted April 23, 2015 I see the relay has 3 pins on the low power side but the buzzer only has 2 pins do I still need to run a ground from somewhere else? Link to comment Share on other sites More sharing options...
G+_Cameron Skinner Posted April 24, 2015 Author Share Posted April 24, 2015 DeWayne Shorts I see the relay has 3 pins on the low power side but the buzzer only has 2 pins. What pins do I connect from the buzzer? Do I need a connection to the third pin? Thanks. ? Link to comment Share on other sites More sharing options...
G+_DeWayne Shorts Posted April 24, 2015 Share Posted April 24, 2015 You have +, - and s. + and s connect to + lead. Link to comment Share on other sites More sharing options...
G+_William Foster Posted May 2, 2015 Share Posted May 2, 2015 anyone got a link to the lights that was on last weeks show? I would like to get the correct stuff..... Thank all of you for your help..... Link to comment Share on other sites More sharing options...
G+_Steve C Posted May 2, 2015 Share Posted May 2, 2015 Just a heads up, that 1 ch. switch that Fr. R. said could be used for LED lights but was actually made to operate a smoke machine, those will probably only turn on for 1 sec. each time, just long enough to detonate the smoke canister. It would work for lights but just for 1 sec. each time. Link to comment Share on other sites More sharing options...
