https://www.electronics-lab.com/interface-oled-0-96inch-lcd-arduino/
This tutorial is going to teach you the basics on using OLED 0.96inch LCD128x64 with Arduino. OLED 0.96 inch is a monochrome graphic display module with a built-in 0.96 inch, 128X64 high-resolution display. OLED 0.96inch is able to work despite the absence of backlight. In a dark environment, contrast of OLED display is higher than […]
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 […]

A WiFi (Wireless Fidelity) is a technology that uses the 2.4GHz UHF and 5GHz SHF ISM radio bands to allow devices such as computers, smartphones, digital cameras, tablet computers, etc. to network. Nowadays the WiFi technology is being used by cities to provide free or low-cost Internet access to residents. The WiFi is inexpensive and […]
Wrist Mount Digital Altimeter
https://www.electronics-lab.com/wrist-mount-digital-altimeter/
This project is a simple wrist mount digital altimeter which is a device used to determine altitude. This design uses atmospheric pressure to calculate the altitude of its location. The lower the atmospheric pressure, the higher the altitude. The project is comprised of a microcontroller (MCU), an 84×84 pixel graphic LCD and a barometric pressure […]

Using Efficient SPI Peripherals for Low-Cost MCU-Based IoT Designs
https://www.electronics-lab.com/using-efficient-spi-peripherals-for-low-cost-mcu-based-iot-designs/
by Warren Miller @ digikey.com: Efficient Internet of Things (IoT) designs must balance a host of requirements that often work against each other. Low cost is important, but often supporting all the key features required by the application increases MCU pin count and memory size—two things that work against low cost. Low power is also […]
