Control 8 relays using ESP32 and a web interface
Control 8 relays using ESP32 and serial monitor
In this tutorial we will see how to address each relay individually with a NodeMCU32S microcontroller and 74HC595 shift registers. At the end of this tutorial you will also be able to control each relay using the serial monitor. This tutorial follows on from the...
Controlling 8 relays with ESP32 and shift register
In this series of tutorials, we will see how to drive a multitude of relays with a NodeMCU32S microcontroller and 74HC595 shift registers. We will then see how to address each relay individually. Finally, we will create a web interface to control each relay via the...
