Hello. Tell us which relays can be used other than those specified in the BOM.
This is a polarized relay? After switching the state, are they de-energized?
Or is the voltage on the relay winding constantly present?
Thanks.

Hello. I was very interested in the LDR Pre MkII project-LDR volume control and I/O switching.There is a desire to build for yourself. There is an Arduino nano with Atmega328PB.
Using the gcUploader program, I managed to upload the ldr_pre_mkii_g_v1.17 firmware for OLED 128x64.
I want to use the Winstar OLED Controller WS0010 display
Using the gcUploader program, I Fill in the firmware LDR_Pre_MkII_W_v1.24. Is programmed correctly. By the glow of the LEDs on the Arduino Board, you can see that the program has started and started working (my opinion).
However, the display shows absolutely nothing. Use an I2C adapter.
I need help. Please tell me what I'm doing wrong.Maybe I have the wrong connection scheme. Or something is wrong with the firmware.
And if possible, see the sketch for Arduino LDR_Pre_MkII_W_v1. 24
I hope for your help. Thanks. Sorry for my English. I use Google translate.

Tell me what address is set in the firmware for oled 1602 LDR_Pre_MkII_W_v1. 24
define LCDADDRESS _?x??

There are no more Atmega328PB based Nano boards available for purchase on aliexpress or anywhere else. This will probably hike the price of the kit upwards soon, as I would need to replace non-PB with PB ICs on generic Nano boards to keep this whole project alive.
Crazoff/Smith Wesson. Why are you using two identities?
Smith Wesson must be removed.
Problem with OLED 2.42 DIY MORE
Maybe somebody had similar problem ?
Finished my project LDR Pre MkII fed days ago and start for running.... But seems that OLED indicator gives me to stop for the next steps. It is does not show any indication and always black. I found that if it is not connecter to the main board then NANO starts with their small LEDs and react to the encoder switch , but if OLED connected to the board, the NANO LED`s blink as low powering (see photos). I found that this happens when only SDA or/ and SCL is connected to the main board.
Any recommendations to find and fix the problems?
Thanks

It seems problem with board, because I checked with 0.96` OLED with I2C (driveSSD1306) now and situation is similar as with old 2.54` OLED .
Do I need to reflash NANO ?

If the smaller oled is not the same resolution, same controller and i2c address it will not work.
What is the measured 5v line voltage with oled connected (Vcc on oled)?
VCC on OLED supply line 2.02V DC
Power supply 3 x 5V DC

Smaller OLED the same resolution 128x64, controller SSD1306 (read that works with SSD1309),regarding address - I don't` t know.....

Thanks Dan, it is the same OLED version on my project with modification (acc. instruction manual) too, but as I mentioned - I`m in the same status - no any indication.
