relay circuit


Posted on Feb 5, 2014

The intended result is that the relay oscillates and the LEDs flash when the button is pressed, however when I press the button the leftmost LED lights constantly and nothing else happens. I get voltage across the left LED, the resistor and the capacitor, but no voltage across the second LED and I can`t hear my relay oscillating. There`s no sound

from it. The stripboard drawing is some help, but is still not a schematic. For example, the stripboard drawing doesn`t show the polarities of the LEDs or the cap.

Since I`m getting voltage across my capacitor which is in parallel with the coil, does this mean there`s probably an issue with my relay and I should just get a new one Since I`m getting voltage across my capacitor which is in parallel with the coil, does this mean there`s probably an issue with my relay and I should just get a new one The relay should operate every time you apply power directly and release every time you remove power. If it does, then the coil of the relay is doing what it is supposed to. The next issue is to get the relay operating every time you press the button and releasing every time you release the button. Run the power through the NC relay contacts, add the cap and the relay should oscillate when you hold down the button and stop when you release the button. Then, you can add the LEDs and get them to flash. The relay should operate every time you apply power directly and release every time you remove power. If it does, then the coil of the relay is doing what it is...
