OTA Online Upgrade for Arduino

1. Introduction to OTA

OTA stands for Over-the-Air, which refers to the technology for remote management of SIM card data and applications through mobile communication (GSM or CDMA) over the air interface. The air interface can utilize WAP, GPRS, CDMA1X, and SMS technologies. The application of OTA technology allows mobile communications to not only provide voice and data services but also to offer new business downloads. In the Internet of Things (IoT) field, especially in embedded devices like the ESP8266 Wi-Fi

Controlling Servo Motors with Arduino: A Simple Guide

Today, we will use the Arduino development board to control a servo motor, creating a simple 2-degree-of-freedom gimbal. Based on its rotation characteristics, the gimbal can be divided into a horizontal gimbal that can only rotate left and right, and an omnidirectional gimbal that can rotate both left and right as well as up and down. Generally, the horizontal rotation angle is 0° to 350°, and the vertical rotation angle is +90°. The constant-speed gimbal has a horizontal rotation speed

Understanding ARM CPU Architecture and SoC Design

1. Computer Architecture
Before understanding computer architecture, let’s first get to know a few key figures who made significant contributions to the invention of computers.
1. Charles Babbage
Known as the father of the mechanical computer, Babbage was a British nobleman who created the first difference engine, achieving a calculation precision of 6 decimal places. He later designed a 20-digit precision difference engine, reaching the pinnacle of mechanical design.
From 1985 to 1991, the London Science

Getting Started with SDR: ADI ADALM-Pluto for Communication Studies

Today, I would like to introduce a very suitable tool for students learning communication technology.
SDR Active Learning Module
Software Defined Radio Active Learning Module
This device is called
ADALM-Pluto
SDR Software Defined Radio Starter Kit
ADALM Pluto SDR is a software-defined radio product based on ADI's AD9363.
Since it is an SDR radio, its most important performance is the frequency bands it supports. The default frequency range is from 325MHz to 3800MHz, supporting a channel bandwidth
