ESP32 Web Server Tutorial with a BME280 Sensor
https://www.electronics-lab.com/esp32-web-server-tutorial-bme280-sensor/
Our friends at educ8s.tv uploaded a new tutorial on their youtube channel. It’s about an ESP32 web server along with MBE280 sensor. Welcome to another ESP32 video tutorial! In this video, we are going to build a simple HTTP Web Server on an ESP32 board with a BME280 sensor. We are also going to learn […]
BPi M2 Zero, A Clone of Raspberry Pi Zero
https://www.electronics-lab.com/bpi-m2-zero-clone-raspberry-pi-zero/
A few days ago, we talked about the Banana Pi M2 Magic as the smallest Banana Pi board. Now we have the Banana Pi M2 Zero, another board by Sinovoip that follows the Raspberry Pi Zero form factor. The BPi M2 Zero features Allwinner H2+ quad-core processor with 512MB SDRAM memory. The board size is […]
Details of Waveshare e-paper displays
https://www.electronics-lab.com/details-waveshare-e-paper-displays/
Erich Styger has a nice write-up on Waveshare e-paper displays: I have used E-Ink displays in projects three years ago, but from that time the technology has greatly evolved. That time displays were hard to get, expensive and difficult to use. Now things seem to change with e-ink displays available to the maker market :-). I’m […]
Design of a Korg Nutube Amplifier
https://www.electronics-lab.com/design-korg-nutube-amplifier/
Karlwoodward @ www.rs-online.com/designspark is in the process of designing a “guitar pedal” for amplification and distortion using the Korg Nutube we featured earlier. The Part 1 of a series of articles goes through the basic aspects of tubes and valves, the pros and cons on using a Nutube valve as well as discussing about low gain […]
R&S®NGE100 power supply series with WiFi option
https://www.electronics-lab.com/rsnge100-power-supply-series-with-wifi-option/
The R&S®NGE100 power supply series consists of robust, high-performance, affordable instruments. They offer high efficiency combined with low ripple plus a variety of comfort functions that are not usually found in this class of power supplies. The R&S®NGE100 power supply series consists of the R&S®NGE102 two-channel power supply and the R&S®NGE103 three-channel power supply. Both […]
How to drive Nokia 5110 84×48 LCD display with Arduino
https://www.electronics-lab.com/drive-nokia-5110-84x48-lcd-display-arduino/
In the previous tutorial I showed how to build a weather station using DHT11 and BMP180 with an Arduino. However, the project has a downside which is the power consumption of the 16X2 LCD. If we were building a battery powered project with the desire to last for several weeks and probably several months, like […]

Atmel ATmega8 – A World-Famous Microcontroller Created By Two Annoyed Students
https://www.electronics-lab.com/atmel-atmega8-world-famous-microcontroller-created-two-annoyed-students/
AVR is a family of microcontrollers developed by Atmel beginning in 1996. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers. The Atmel AVR core combines a rich instruction set with 32 general purpose working registers. Atmel’s ATmega8 comes from the AVR line of microcontroller and it is a gem of the modern maker movement. It is used as […]
CH340E, A New Small Serial to USB Chip
https://www.electronics-lab.com/ch340e-new-small-serial-usb-chip/
WCH, a Chinese integrated circuits manufacturer, has just released a new serial to USB chip called CH340E. Unlike other CH340 chips, it doesn’t require an external crystal and also needs less PCB space and BOM. CH340 is a 3x3mm tiny chip comes in MSOP10 package and has 10 pins. Although it is smaller than other alternatives, it is […]
Using an ATmega328 without a crystal
https://www.electronics-lab.com/using-atmega328-without-crystal/
Here is another guide from David Johnson-Davies @ technoblogy.com explaining how to program an ATmega328 on a breadboard using the Arduino IDE. The guide is focused on how to use the internal clock of the microcontroller and how to achieve this using the Arduino environment. By default Arduino IDE doesn’t include a Boards option for an […]
