How to interface OLED 0.96inch LCD with Arduino
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 […]
Two books for makers that you should read!
https://www.electronics-lab.com/two-books-makers-read/
educ8s.tv uploaded the last video of this season and it’s a different one! The first one, is this: Practical Electronics for Inventors. Since I studied computer science and not electronics engineering at University, I needed to find a good book to study electronics myself. After a lot of search I concluded that this book was […]

https://www.electronics-lab.com/entry-level-auto-ranging-digital-multimeters-reviewed/
If you want to buy a digital multi-meter for under $50 then this article is for you. It compares 8 models fitting the certain criteria. With the current DIY/Maker movement in full swing, one thing that almost all of us need is a good Multi-meter. When shopping for one, it was decided right away that […]
Bridging ISM radio and wifi for lunch money
https://www.electronics-lab.com/bridging-ism-radio-wifi-lunch-money/
Johan discuss about ISM/Wifi bridge using RFM69, code and schematics is available on github. The ESP8266 has taken the maker community by storm and the hype is well deserved. Before the ESP we had the HopeRF ISM radio RFM12 and its successor RFM69. So is the ESP8266 an RFM69 killer? I would say no. Hell […]
ARM bought by Japanese Softbank for 32 billion dollars
https://www.electronics-lab.com/arm-bought-japanese-softbank-32-billion-dollars/
by Jan Buiting @ elektormagazine.com: Confirmed last Monday (18 July 2016): 100%-thinkware-firm-and-brilliant-bunch-of-Cambridge-mathematicians/computer-scientists, ARM, is to be bought by Japan’s Softbank for £24 bn ($32 bn). In official words: the board of ARM is expected to recommend shareholders to accept the offer — which is around 43% up on its closing market value of £16bn8 last Friday. […]
“Chipiplexing” efficiently drives multiple LEDs using few microcontroller ports
https://www.electronics-lab.com/chipiplexing-efficiently-drives-multiple-leds-using-few-microcontroller-ports/
by Guillermo Jaquenod @ edn.com Actual microcontrollers have powerful bidirectional I/O ports, and you can use different techniques to fully exploit such capabilities. Recent Design Ideas described the “Charlieplexing” method as an effective way to drive M=N×(N–1) LEDs using only N bidirectional I/O ports and N resistors (reference 1 and reference 2). Unfortunately, using Charlieplexing […]
TV Tuner IR remote with a PIC16F684
https://www.electronics-lab.com/tv-tuner-ir-remote-with-a-pic16f684/
Tahmid built a TV tuner IR remote with a PIC16F684: I then proceeded to write an IR transmitter using the PIC16F684 (using the MPLAB X IDE and XC8 compiler), following the timing information from the extended NEC protocol. In order to connect all the keys, I connected them in matrix keypad form. In order to power the […]
Homebrew Multimode Digital Voice Modem adapter
https://www.electronics-lab.com/homebrew-multimode-digital-voice-modem-adapter/
Florian Wolters made his own version of MMDVM adapter: During experiments with digital voice mode in hamradio I discovered a nice project describing an adapter for D-Star, DMR and other digital modes based on an Arduino Due and a little PCB to be put on top. This unit is called the Multimode Digital Voice Modem […]
Not a battery or a supercap, but a ‘thin laminate energy device’
https://www.electronics-lab.com/not-battery-supercap-thin-laminate-energy-device/
Murata’s UMAL is a low-profile high capacity energy device. Designed to meet the demand for a slim high capacity energy source with a maintenance-free extended life cycle in wireless sensor nodes, the UMAL has charge/discharge and life-cycle characteristics superior to conventional secondary batteries. By Graham Prophet The UMAL has a nominal voltage of 2.3 VDC, […]
Accurately simulate an LED
https://www.electronics-lab.com/accurately-simulate-led/
Jon Roman and Donald Schelle have a design idea on how to simulate a high power led to test your driver circuit. Testing the driver circuit using LEDs, although easy, yields only typical results because the tests don’t factor in worst-case LED parameters and often generate undesirable light and heat during driver debugging. Although using […]
