In this tutorial, I will be demonstrating, how we can control servo motors with thumb Joystick and Arduino. We will control two servo motors with the help of Analog Joystick. Before going to understand connections and programming, we will take a brief look at Joystick and servo motor to refresh the basics. We will also […]

Arduino is the most used and preferred micro-controller board since its development. Nowadays, there are some alternatives for Arduino as well. Blue Pill STM32 (STM32F103C8) is one of them. STM32F103C8 microcontroller is based on ARM cortex M3 architecture. Which makes it more efficient than Arduino. To program Blue Pill STM32, we have two options, we
As we know, NodeMCU is an open-source IoT platform for Lua based firmware developed for ESP8266. Espressif Systems developed this amazing board. Usually, NodeMCU comes with an inbuilt Lua interpreter, but the preferred way is to program NodeMCU ESP8266 with Arduino IDE. NodeMCU is one of the most widely used development. What is NodeMCU? As discussed earlier, NodeMCU is an

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
