Does anyone know why the relay in the circuit I attached (2 pictures) inst changing?
Facts...
red line = 9.3 ish volts
blue line = ground
The potentiometer works - I tested it and it does vary the voltage...
LED lights are in the correct direction...
The resistors you see are 470 Ohm resistors.
The relay part is manufactured by Shinmei - RSB-5-S
^^^Specifications are on https://info.tactnet.co.jp/shinmei/e/product/pdf/E_RSB.pdf
No matter what I do the red LED does not turn on, and the Green LED does not turn off. What am I doing wrong?
I was looking for the relay online when my Internet went south. I notice in Boncuk's pinout that one pin shows + for the coil. Does this relay have an internal diode across the coil and if so, is the polarity connected correctly? Also, if the side of the relay with the bar (line) is the coil pins, they both look to be going to 9 volts.

I did find the pinout and yes, there is an internal diode across the coil. Pin 1 (+) and pin 16 (-). Additionally it does look like the coils pins are both tied to the supply of 9 volts or whatever.
the "+ sign" you see is the zero/zero reference mark which cannot be suppressed in Eagle.
That kind of relay is manufactured by many companies and fits perfectly into a modified DIP-16 socket.
My example is of the "FINDER S30", which might have different pin numbers (according to German standards the common pin is 11, 21, 31 etc, NC pins are 12, 22, 32 and NO pins are 14, 24, 34.
Using the link once I had good Internet back the relay does in fact have polarity on the coil. They even offer it with a reverse polarity for the pins. Tonignt was just one of those nights. My Internet speed began to slow, the real slow then a stop. Rebooted the modem and it would not lock on. After a few min it locked on the node and been fine ever since. I hate it when that happens. Anyway as someone else mentioned long before me, on the breadboard it doesn't look right. Looks like power + is running to both sides of the relay coil. I guess when the OP returns we will know.
The coil is shorted out with no ground, show the rest of the board, this forum hates secrets.
I bet the OP already figured that out and that why he hasn't posted again.
I got it working... And it was because I stupidly had A1 and A2 (Boncuk's diagram) connected to + instead of one connected to ground. It turns out that the pin left of the S in Shinmei connects to ground, and the opposite pin connects to +.
I'll post a schematic if I have any other future problems
And I would have replied earlier, except that I was sleeping.
The meaning of "cricket, cricket" is that it is so quiet you can hear the insects chirping, a big, empty silence. I see that it does not translate into some languages. I wonder if it translates into Brit, Ozzie, Canuk, Francais, Espanol, Cyrilic based languages, several Asian languages, and Near Eastern languages.
The "crickets" line is often used for talking to politicians. You ask them why they are crooked or corrupt, and their answer is " " absolutely nothing. They are so quiet, you can hear the crickets chirping.
