Overview In this article, we want to take a deeper look at L293D. L293D is the most widely used IC to drive motors and it is necessary to know it’s theory, diagram, simulation, and pinout. Here we will discuss all these subjects. L293D & Motors; What's the story? Motors used in academic robots normally operate at 5, 6, 9, 12 or 24 volts. Depending on the model, the manufacturing method, price, etc., their current is about 100 mA to 5A. You can use motors in several ways. One method is to con...

Overview It would fun to see how your Instagram posts perform in action! We are going to build a gauge that shows your Likes per minute speed. In this article, you will learn how to get data from web pages by ESP8266 and send them to Arduino to analyze and run other actuators.  What You Will Learn Connect the ESP8266 to the internet and get data from web pages.

AD9833 Signal Generator Module Features In many projects we need a signal with a specific waveform and frequency. The AD9833 signal generator module is a low-cost module for such applications. This module is capable of generating sine, triangular, square and half-square waveforms. You can adjust the frequency of generated signal from 1Hz to 12.5MHz. The communication protocol of this module is SPI. AD9833 Signal Generator Module Pinout This module has 7 pins:Ref: Re...

Overview There are two main ways to program the STM32F103C8T6 module, also known as the STM32 Blue Pill: • Serial and USB to TTL converter • ST-Link Tip Sometimes you might find out that the STM32 module you have is not original. And it can’t be programmed through serial. Therefore, we suggest you use ST-Link to program the STM32 Blue Pill. Required Materials Hardware Components STM32F103C8T6 Blue Pill × 1 ST-Link/V2 Programmer × 1 Male to Male Jumper Wire × 1 Software Apps Ar...

Introduction Similar to Arduino IDE, Platform-IO is a programming environment for all types of microcontrollers. It provides an easier programming process and is available as an extension for the VS Code software. One notable advantage of Platform-IO IDE over Arduino IDE is that it automatically selects the appropriate port. In addition, Platform-IO IDE offers code suggestions to help complete and modify your code, and it eliminates errors caused by case sensitivity in Arduino IDE! Some other attractive fea...

NanoPi Duo Board Features The NanoPi Duo Board functions like a compact computer, offering a range of features. Its main processor—Allwinner H2+—provides sufficient processing power through its Cortex-A7 quad-core processor. The board also comes with DDR3-type Memory available in two models: 256MB and 512MB.The NanoPi Duo board includes USB ports that allow you to connect peripherals such as a keyboard, mouse, storage device, or Wi-Fi dongle. In addition, you can connect the internal Ethernet port o...

Introduction Since most Arduino boards don't support wireless communication, we have to connect them to a computer—using a cable—in order to program them. But, dealing with all those cables can be frustrating, right? In this step-by-step tutorial, we're going to show you how to wirelessly program your Arduino using Bluetooth. It gives you more flexibility when working on your projects. Whether you're an Arduino pro or just starting out, this step-by-step guide will take you through the entire process—...
