It comes from an early 90's sony discman. Thank you!I recently attended a press event where a dozen or so companies pitched their latest technologies. The presenting organizations ranged from semiconductor IP providers to component distributors, from connector companies to design and manufacturing services firms. Although the spread was diverse, one thread tied many of the presentations together:. Flex, formerly Flextronics, is an electronics integration and manufacturing services company.
At the event, company representatives indicated that they employ roughly 4, design engineers worldwide. But they also mentioned that it is becoming more and more difficult to acquire good technical talent, not just in the U.
The U. Bureau of Labor Statistics estimates that the number of electrical and electronics engineers will grow by about 7 percent from towhich is on par with other occupations. Of course, given the increase of electronic content in conventional and unconventional digital systems, average job growth may not suffice.
At the same time, the knowledgebase required of a modern engineer has shifted. The IoT demands engineers with a jack-of-all-trades makeup, including technical proficiency in sensing, computing, connectivity, application software, and systems engineering. The Bureau projects the number of software developers already triple that of electronics engineers to grow 24 percent throughwith the other disciplines struggling to keep pace. The discussion then becomes how to maximize the human resources at hand.
Here, Arduino provides an interesting case study. The open source prototyping technology was originally intended to educate prospective engineers on the intricacies of embedded hardware development. There are orders of magnitude more developers there, and we can be more inclusive of them with tools and processes. Silicon Labs has taken this concept to the extreme.
AS7261 Spectral Sensing Engine
The company recently began a systematic rollout of its Gecko OS platform, which integrates embedded platform, connectivity, and development software for select Arm-based silicon products Figure 1. The goal is to capture high volume customers by providing a black box and command API that abstracts underlying complexity and accelerates time to market. Engineering, by definition, is the act of tweaking portions of a design to yield better performance or product differentiation.
Removing one component from the house of cards could bring the entire infrastructure crashing down, and no realistic amount of support will be able to save it. On the other hand, if the Gecko OS is flexible enough to support slight variations in a few key consumer applications, it could tip the hour glass on embedded engineering as we know it.
Underscoring all of this is continued consolidation in the semiconductor industry. Maybe artificial intelligence will require new classes of hardware that change this dynamic, but even so it seems that startups making meaningful advances will quickly be gobbled up by larger and larger players in a smaller and smaller industry. Software and applications are. Perhaps software engineering becomes so saturated that the pendulum swings back to hardware innovation.
For now, beware the black box. In the long run it will impede progress for individuals and industry alike.

Motor Control.The Christmas Light Controller is a fun project that lets you provide public access to your outdoor lights during the holiday season — perfect for homeowners and parties, where visitors can select a number of lighting transitions via a mobile phone.
The DIY project requires a basic Arduino relay board, flashing the ready to use Arduino firmware in the relay board, setting up your own online IoT server, and configuring the solution. Then, you can let visitors and neighbors securely control your outdoor lights by simply navigating to your domain name using a browser on their mobile phones. The web-based light controller user interface is designed to be used by multiple visitors at the same time and updates in real time across all connected browsers.
The AS7261 Color Sensor: Measuring Color in XYZ
The board can be wired directly to the mains and to the Christmas lights. The server solution includes the IoT communication module and a web user interface for controlling connected edge nodes. You can run the server software on your own computer, such as your own PC, but that limits the use of the Light Controller solution.
The benefit of installing the Light Controller solution on an online server is that it enables easy and secure public access to the Light Controller's public user interface. Any person can use their mobile phone and control the lights without requiring access to your local network. If the server is running on your local network, only users with access to your private network can control the lights. Most developers probably think about Amazon or Microsoft Azure's services when considering the server side of their IoT solution.
These high-end services are great if you need to scale up to millions of connected devices. The website lowendbox. Connecting more edge nodes requires more memory, but the VPS we selected has memory limitations 64MB. In any event, you will most likely connect only one or two ESP Light Controller edge nodes to the online server. All VPS providers, including low cost providers, typically provide a web-based user interface from where you can manage your VPS.
The operating system of choice is typically a flavor of Linux. After installing the Linux operating system using the web interface, the server will be online and be ready for you to log on and manage. The Light Controller App's server-side code is designed in the Lua scripting language and runs on top of the Mako Server's application engine. A general problem with IoT protocols is that they typically cannot be used without authentication since this would leave the door completely open.MicroPython works great on ESP32, but the most serious issue is still as on most other MicroPython boards limited amount of free memory.
This repository contains all the tools and sources necessary to build working MicroPython firmware which can fully use the advantages of 4MB or more of psRAM. It is huge difference between MicroPython running with less than KB of free memory and running with 4MB of free memory. You can discuss about this MicroPython port on its forum. Network module.

It is running The setup is as follows: 1 Channel 1 set to supply D Tyler 1.A near-IR channel and LED drivers with programmable currents increase application flexibility, including support for electronic shutter applications.
The I2C interface presents a traditional register based device interface, while the UART interface allows high-level command access to the ASx device features. The iSPI board includes unpopulated device pads for the installation of standard LED light sources suited to the specific spectral needs of the application.
By default, the LED pads are unpopulated. The ASN integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in an LGA package that provides a built in aperture to control the light entering the sensor array.
This highly integrated device delivers 6-channel multispectral sensing in the visible wavelengths from approximately nm to nm with full-width half-max FWHM of 40nm.
Getting Started with ESP8266 and Arduino: ESP8266 Arduino Interface
An integrated LED driver with programmable current is provided for electronic shutter applications. The AS integrates Gaussian filters into standard CMOS silicon via nano-optic deposited interference filter technology and is packaged in a LGA package that provides a built in aperture to control the light entering the sensor array. The AS is designed with a high dynamic range to measure any light in the visible range VIS in environments from sunlight to dark rooms, dimmed LEDs, or dark colored monitors.SparkFun Arduino Comparison Guide
Each of the channels has a filter to control its optical response, which allows the device to accurately measure ambient light and sense color.
These measurements are used to calculate chromaticity, illuminance and color temperature, all of which are used to support various potential applications.
The TCS is ideally suited for use in smartphone applications to improve color measurement and intensity of ambient light conditions. The sensor can also be used to assist the smartphone camera sensor with color sensing of ambient light to enhance and improve picture white balance to deliver more realistic and vibrant images.
