circuitbasics.com talks about the I2C protocol, it's use and it's advantages and disadvantages. I2C combines the best features of SPI and UARTs. With I2C, you can connect multiple slaves to a single master (like SPI) and you can have multiple masters controlling single, or multiple...

by David_Dragino @ instructables.com This is an example to show how to get sensor data from a remote Arduino via Wireless Lora Protocol. The exampels requries below hardwares: 1) Client Side: Arduino + Lora Shield (868Mhz) + DS18B20 (Temperature Sensor). 2) Server Side:...

Gustavo Reynaga shows us how to you can flash your ESP-01 and esp-201 with Arduino IDE and upload any other firmware with ESP flash tools. Hi folks, now I'll teach you how to make your programmer to the ESP-01 and ESP-201, (perhaps serve with other models) using an Arduino UNO, a...

circuitbasics.com talks about the SPI serial communications protocol: One unique benefit of SPI is the fact that data can be transferred without interruption. Any number of bits can be sent or received in a continuous stream. With I2C and UART, data is sent in packets, limited to...

Yahya Tawil tipped us with his latest article that explains how Arduino works from an electronic design perspective. Most articles explain the software of Arduinos. However, understanding hardware design helps you to make the next step in the Arduino journey. A good grasp of the...

In this video "DanTheAwesomeMan" takes us on a tour of the visible internal workings of a 27C512 EPROM microchip, with the aid of an optical microscope at up to 800x magnification. What's inside a microchip ? -...

LTM8003 is a step-down DC/DC µModule (micro-module) regulator with a 40V input voltage rating (42V abs. Max.) and 3.5A of continuous (6A peak) output current. The LTM8003’s pinout is FMEA (failure mode effects analysis) compliant, so the output voltage stays at or below the...

James O'Neill explores a Transcend SD that he believes it's the smaller Linux server. It's actually a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package. The way these cards works is different from the better known Eye-FI card. They are SERVERS : they...
