IoT based home security with fingerprint authentication
Previously, we have studied to interface fingerprint scanner with NodeMCU. We have also studied that, we can interface I2C OLED display with NodeMCU with less GPIO pins. Today, we will combine those both tutorials to build IoT based home security with fingerprint authentication. Let’s start with project requirements. Component List: NodeMCU OLED Display (SSD1306) Fingerprint […]
