Hello Folks ;
Posting here for the first time ever, so please excuse me for any mistakes done and guide me to do a better job in the future.
I bought those esp32’s with integrated OLED on them aliexpress esp32
I’m aiming to create a bread proofing box, where I can read the temp and humidity from the box and control a heating element for bulk fermentation. up to know the project is just about programming as I’m waiting for the heating element and the DHT sensors to arrive. All is going well except I have the first column on the screen has some characters on it and I don’t know where its coming from and i do not know how to correct it.
Im sharing my code below and posting pictures of the characters on the OLED screen.(very first coloumn)
Thank you in advance
