https://www.electronics-lab.com/get-sensor-data-remote-arduino-via-wireless-lora-protocol/
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: Arduino + Lora Shield (868Mhz) + Yun Shield + USB flash. How […]
The cheapest ESP8266 programmer!
https://www.electronics-lab.com/cheapest-esp8266-programmer/
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 few cables and optionally a button […]
Basics of the SPI Communication Protocol
https://www.electronics-lab.com/basics-spi-communication-protocol/
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 a specific number of bits. Start and stop conditions define the beginning […]
Understanding Arduino UNO Hardware Design

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 ? – [Link]
LTM8003 – 40VIN, 3.5A Step-Down μModule Regulator
https://www.electronics-lab.com/ltm8003-40vin-3-5a-step-down-%ce%bcmodule-regulator/
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 regulation voltage in the event of short-circuit to GND, short-circuit to […]
Exploring the Transcend Wifi-SD card
https://www.electronics-lab.com/exploring-transcend-wifi-sd-card/
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 don’t upload pictures to […]
An Introduction to MSP430 Launchpad
https://www.electronics-lab.com/brief-introduction-msp430-using-launchpad-msp430g2553/
Rahul Sreedharan introduces us to TI’s MSP430 microcontroller using LaunchPad board. In this tutorial we will be exploring the workings of a MSP430 based microcontroller from Texas Instruments. MSP430 is developed by Texas Instruments as an extremely low power 16 bit architecture for use in low power, low cost, energy constrained embedded applicationsThe Hardware used […]
