I work on the book "Make - Electronics" doing some experiments. One of these is working with a relay. The simple schematic is this one:
The circuit that I build works to 95%..... The left LED is lighting up when connecting to power, which means the relay is passing through the current. When I press the button, the left LED is turning off correctly, but the right one doesn't light up. I tested both LEDs by switching their places and got the same result. So I know that both LEDs are working. But i do not find the error... So I would think the relay is working, right?
