    I'm wiring up a control box for my Ox. I have indicator led's wired up so that when my 24v psu is powered the led is lit. I'd like to also put an indicator light in for when the arduino is connected, i have an led indicator. The LED's are 24v, so I'd like the arduino to trigger a normally opened relay to send the 24v power to the led. Attached is how I have it wired, with the signal coming from the arduino 5v, but it's not activating the relay coil to closed. The arduino is powered through usb. Any help or suggestions?

    Thanks. relayarduino.PNG
