Hi,
This is the last circuit I've tested and now on my breadboard.
It is working. When I press a button the bulb goes ON, when I tap it again - it goes OFF.
BUT, ...
1) The voltage of the power circuit when bulb off is 11.7V - great.
2) The voltage measured at the input of 555 IC when bulb ON - 5.7V - for the 555 ok but for the receiver?
3) The voltage measured at the input of the MOC3052 is only 1.06V - at the minimum?!
I am afraid that the RF receive wouldn't power with that voltage. I am not sure about the Current.
I am afraid also not to blow up again the optocoupler, therefore these values of the resistors.
Maybe some of the resistor values are too big?
Now I have 2 LEDs ... One is just showing 12V supply. The other one is lighting when signal from the 555 IC.
Actually I would like to have only one LED, which to illuminate when the bulb is OFF.
... but only if that will be safe enough.
Unfortunately I will get the receiver after 8th of MAY as the Customs will not work by then - there are a lot of holidays now here.
When I have it I will try to bypass the relay and to use directly the signal to drive the MOC3052. This will save me space, relay-click noise, and would require less power to operate, am I right?
Cheers
and looking for your comments...
p.s. The buzz noise... is comming from the TRIAC, isn't it? Any ideas how to easily avoid it? The same noise is comming from the PIR sensor.
Last but not least... when 230V power applied, the bulb is switched ON/OFF randomly. Ones ON, sometimes OFF. I will need to add elements to reset the 555 IC.
