Built with a RISC-V core, this chip is gaining popularity among developers looking for a cost-effective yet robust solution for IoT applications. Let’s dive into …

The 1.77" ST7735 TFT LCD is a popular small-sized display, widely used in DIY projects for its vivid colors and compact size. Coupled with the powerful ESP32 microcontroller, it becomes an excellent choice for IoT projects. This tutorial will guide you through the process of interfacing the ST7735 with the …

In this tutorial, we will explore how to configure and use the ADC (Analog-to-Digital Converter) in the STM32F407 microcontroller in scan mode with DMA (Direct Memory Access). This setup is particularly useful when working with multiple analog inputs that need to be converted into digital values efficiently. We will also …

Django, a high-level Python web framework, can be a perfect choice for building dynamic web applications. Combining this with the Raspberry Pi—a versatile, compact computer—enables developers to deploy a robust and affordable web server. This guide walks you through setting up a Django web server on a Raspberry Pi.

Using a PT100 RTD (Resistance Temperature Detector) with an Arduino and connecting it to the Arduino IoT Cloud via Wi-Fi allows you to remotely monitor temperatures with high accuracy and reliability. In this tutorial, we’ll walk you through the process of setting up your PT100 sensor with an Arduino that …

Controlling a DC motor with an ESP8266, L298N motor driver module, and Arduino Cloud provides a flexible and efficient way to automate motor control remotely. This tutorial will guide you through the setup, wiring, and code needed to achieve this.

Binary search is an efficient search algorithm that is particularly useful for finding elements in a sorted array. In comparison to linear search, which goes through each element one by one, binary search dramatically reduces the number of comparisons by dividing the search interval in half repeatedly. This is especially …
