i'm new with the arduino board and started to do some experiments with it.
i'm trying to use this LED flashlight
starting from the basic example of Blinking LEDs available on the tutorial section of arduino.cc website.
here is the problem:
- if i connect the lamp to the port 13 the blink effect works but the brightness is very low.
- if i connect the lamp to +5v the brightness is ok but, obviously, the blink effect is not achieved
so... i tried to use a he721a0500 hamlin's relay to try to obtain the blink effect.
passing as input the pulse coming from the port 13 and the 5v electrical supply..as i hoped that in this way the component would work as a switch.
unfortunately it seems that won't work.
hope that somebody could help me (and that the problem explanation was enough clear)
thank you in advance.
