Mini Arduino Lux Meter
https://www.electronics-lab.com/mini-arduino-lux-meter/
Here is a nice build of a LUX meter using BH1750 sensor and a Nokia 5110 LCD. The meter is controlled by an Arduino Pro Mini and is powered by a Li-Ion battery. The LCD backlight is controlled according to environment light and there is graphing capability of the measured light intensity. That’s when I […]
Real time clock and temperature monitor with a DS3231 and a Color TFT
https://www.electronics-lab.com/real-time-clock-temperature-monitor-ds3231-color-tft/
In this video educ8s.tv is building a Real Time clock and temperature monitor with a big 3.2″ Color TFT display. They are using a DS3231 Real Time clock module to get the time, the date and the temperature. The heart of the project is the powerful Arduino Due board, which can drive the display and update […]
ECG Arduino Shield

Electricity Frequency Meter
https://www.electronics-lab.com/electricity-frequency-meter/
This project is about an accurate mains frequency meter that has a bar-graph displaying the relative deviation from nominal frequency. It can work with 50Hz and 60Hz systems. An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the […]
Using Low Cost Hardware to Enhance the User Experience
https://www.electronics-lab.com/using-low-cost-hardware-to-enhance-the-user-experience/
Ken Boak discuss how to build a graphic user interface using cheap TFT toughscreen displays. This article is about using their lowcost graphics co-processor IC to provide a neat user interface for any low-end microcontroller. These days, when you can buy a 7″ tablet for $50, there is all the more reason for makers and hackers […]
