Backdoor uPWM Hack on Arduino for Infrared signals using UART In this blog post we follow up on our recent article about generation of infrared PWM from the Photon’s UART where we suggested that it may be possible to achieve something similar with the Arduino. In our previous attempt the Arduino was only able to generate PWM at 40 kHz and 33 kHz using the same approach. After some investigations we discovered a new approach which provides an even better set of results using the Arduino’s USART. Yes, we were able to generate 30, 33, 36, 38, 40 , 56 and surprisingly the illusive 455 kHz which was not possible on the Photon (using this approach). Read on for the details. Readers should also study our original series of articles on ‘softPWM‘ for a better understanding of the source code which can be downloaded below.

MKR1000 Arduino MKR1000 has been designed to offer a practical and cost effective solution for makers seeking to add Wi-Fi connectivity to their projects with minimal previous experience in networking. It is based on the Atmel ATSAMW25 SoC (System on Chip), that is part of the SmartConnect family of Atmel Wireless devices, specifically designed for IoT projects and devices. The ATSAMW25 is composed of three main blocks: • SAMD21 Cortex-M0+ 32bit low power ARM MCU • WINC1500 low power 2.4GHz IEEE® 802.11 b/g/n Wi-Fi • ECC508 CryptoAuthentication The ATSAMW25 includes also a single 1x1 stream PCB Antenna. The design includes a Li-Po charging circuit that allows the Arduino/Genuino MKR1000 to run on battery power or external 5V, charging the Li-Po battery while running on external power. Switching from one source to the other is done automatically.

carr3r - ESP8266 with FT232RL USB 2 Serial Adapter Hello there ESP8266, you've just got a new fan! The first time I played with ESP8266 "Wifi to Serial" module I used my USB-to-UART cable and Ubuntu, very straight forward. For starters, two things to have in mind: Use 3V3! ARTIK GET A NEW PERSPECTIVE ON loT. Rethink how you get to market with the Samsung ARTIKTM loT ecosystem. Samsung ARTIK is the end-to-end, integrated loT platform that transforms the process of developing, launching, and managing loT products.

Libraries Reference Language | Libraries | Comparison | Changes The Arduino environment can be extended through the use of libraries, just like most programming platforms. Libraries provide extra functionality for use in sketches, e.g. working with hardware or manipulating data. To use a library in a sketch, select it from Sketch > Import Library. A number of libraries come installed with the IDE, but you can also download or create your own.

WiFi Module ESP8266 – 1. Getting started with AT commands ESP8266 is an UART to WiFi module, a really cheap and easy way to connect any small microcontroller platform (for example Arduino) wirelessly to Internet. The ESP8266 is now one of the leading platforms for the Internet of Things. It’s super cheap, and super easy to work with. SerialLCD Serial LCD tutorial by djmatic With a simple four wire connection and the code below, the Arduino can drive serial LCD displays. The main advantage of serial LCD's is that they are easier to wire up, since the Arduino talks to the LCD over a single pair of wires. A very cheap ESP8266 WiFi smart car controlled by phone based on NodeMCU DoitCar is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT), which is the most cost-effective. It is widely applied in many fields, sucha as the electronic lover, college students, Internet of Things (IoT), mobile data collection, etc. DoitCar has a great temptation for the smart car solution. The DoitCar kit is including the car chassis, 2 pieces of 6V motors, NodeMCU WiFi board, motor driven shield board. Especially, all the codes and hardwares are open for all people. Accordingly, the software collections are including android, Webchat, and internet.
