ESP32 | BLE Client (Heart Rate Monitor with OLED and MQTT)

Описание

In this video, we will use the ESP32 with integrated OLED as an internet connected Bluetooth Low Energy Client to a Heart Rate Monitor.

We will display the Heart Rate on the OLED Display and also send it to an MQTT topic to switch a lamp on and off.

Big thanks to Andreas Spiess for his YouTube Videos.
And also massive thanks to Charlize Theron for raising my heart rate again and again.
