Lambda Shield with OLED display

Post by steffenk » 28 Jun 2024 12:09

Hi,

I'm using the Lambda Shield with an Arduino uno wifi and an IPhone since two years. Now I like to use the OLED display SSD1306.
The display works with the test-code "Hello World", but with the sketch for the Shield only the "Bylund-logo" appears on the display and nothing further is happening. The sensors is also not heating.

What can I do?

Best regards steffen

Hello Steffen,

It sounds like you are using the Arduino sketch for the original Lambda Shield instead of the Lambda Shield 2.

Thank you.

Hi Christian,

yes I'm using the Lambda-shield 2, I think I misunderstood your YT-Video that OLED- is implemented, but it's only implementd for the Lambda shield 1-code. Correct?

Hi Steffen,

The video is based on the original Lambda Shield. Functionality is the same but there is some slight differences in how the power supply is detected.

You find all the Arduino sketches for the Lambda Shield 2 on the product website. Using the correct code should solve your problem.

Hope it helps.

Hi Christian,

thank for the support, after comparing the "Hello World"-Oled-example with your lambda-shield-code, i found the mistake. It was the type of OLED display. Now it works.

Best regards steffen
