Organic Light-Emitting Diode Displays (OLEDs)
Organic Light-Emitting Diode (OLED) displays have a number of advantages over LCDs, most notably the following:
- Lower energy usage since there is no need for a backlight.
- A fast response time.
- Integrated I2C communication.
- It is thinner in depth.
Those advantages make it a strong option in many products. However, it is a relatively new technology, so prices are a bit higher. You can see an image of an OLED display in the following figure:

This time, we will develop the same temperature application with an OLED display. The hardware components that we need are as follows:
- A 1.3" OLED display with an SH1106 driver chip (I have one from AZ-Delivery)
- DHT11
The driver chip supports 3.3 V logic level and we can directly interface it with ESP32. Moreover, we don't require any external power source, thanks to its...
