board. The optional boards include a compatible Arduino interface board (including an SD card) and an Intel interface board. Installation and configuration are intuitive. I used the guide to open the Yocto project on the Intel Edison Board to install and configure the board. First we need to connect the Edison through the serial port, and configure the sshd and Wi-Fi, we can use SSH to connect to the Edison after the completion. Because Linux's com

. To get different simulated values, you can change or adjust the pulse width. If you repeat this switching mode fast enough, the result is a stable voltage between 0 and 5 V to control the brightness of the LED. In the graphic below, the green lines represent a regular time period. this duration or period is the inverse of the PWM frequency. in other words, with Arduino's PWM frequency at about 500Hz, the green lines wowould Measure 2 milliseconds each.

Widgeduino-unveiled on Kickstarter recently-is a smart and easy-to-configure window-based on Microsoft Windows platform and Microcontroller System Communication applications based on Atmel-based Arduino board. Essentially, widgeduino communicates with the Microcontroller System through the serial port protocol or TCP/IP. "This includes, among others, keyboard, LED light, pressure gauge, knob, Slider, thermometer, container and button. the intuitive m

LinkIt 7697 is a versatile and affordable development Board that can be used to connect to your network or to your devices, while providing both Wi-Fi and Bluetooth online capabilities. The Development Board uses the MediaTek MT7697 chip, which is a little bit less than the ESP32 microcontroller used in other similar wi-fi/bluetooth development boards, but still far superior to Arduino Uno. After adding the board data and installing the USB driver in

One of the previous intelligent car development data has a file. the types of smart cars that are shared include: Bluetooth Control Two-wheeled car, intelligent car matching procedures, tracking, infrared obstacle avoidance comprehensive program data Daquan; Intelligent vehicle System solution;STM32 two wheel self-ba

It is based on the wiznet W5100 (data sheet) chip.It uses weather balloons to get mea

Over the years, Nodejs gradually developed into a mature development platform, attracting many developers. There are many large, high-traffic sites that are developed using Nodejs, like PayPal, which developers can also use to develop some fast-moving web frameworks.In addition to Web applications, Nodejs is also used in many ways, and this article takes a count of the ten amazing projects that Nodejs has developed in other areas, such as application monitoring, media streaming, remote control,

electronic design, some maker prefers a microcontroller platform, such as the fiery Arduino. But for some of the more complex projects, the 8-bit microcontroller is a bit stretched. For example, a 8-bit microcontroller can barely handle audio with low sample rates, but there's really nothing to do with video processing. However, with the booming of embedded systems, it is easier for both primary and intermediate users to reach them than ever before.B

This is a straightforward description of the function of the closure, which is neither professional nor rigorous, but probably means that the process of understanding the closure needs to be gradual.
