In this video we learn how to drive the new, low cost big, 3.5″ Color TFT display for Arduino Uno and Mega. For the written tutorial please check here. A few weeks ago, I discovered this promising new display on Banggood.com and thought that it might be useful in some of our projects. The price […]
6 Digit Serial Display Driver with CAT4016
https://www.electronics-lab.com/6-digit-serial-display-driver-cat4016/
6 Digit serial display project has been designed around CAT4016 IC from ON semi. The CAT4016 is a 16 channel constant current driver for LED billboard and other general display applications. LED channel currents are programmed together via an external RSET resistor. Low output voltage operation on the LED channels as low as 0.4 V […]
Arduino Body Thermometer + LCD I2C
https://www.electronics-lab.com/arduino-thermometer-lcd-i2c/
This is a body thermometer using a thermistor sensor, Arduino and LCD display. I’ve decided to provide a funny Arduino concept thermometer in case its the middle of the night, pharmacies are not working, you are not feeling well and you want to check your body temperature. If you have Arduino by your side, this is […]
ECG Arduino Shield

Magic Pixel is a universal and handy Bluetooth LED display, which we’ve been developing with focus on ease of use […]
Arduino Analog Signal Graphing on a TFT
https://www.electronics-lab.com/arduino-analog-signal-graphing-on-a-tft/
dmainmon @ instructables.com has build an analog signal graphing project using Arduino Mega 2560 and a 2.8 TFT display. This project is used to display two analog signals as line and bar graphs. Touching the screen pauses the graph and opens a menu to adjust setting for the graphs. The project uses an Arduino Mega 2560 and […]
Quantifying cooling system
https://www.electronics-lab.com/quantifying-cooling-system/
Chris Palmer has built this coolometer project to measure the cooling effectiveness of various fan: I was wondering about how I was going to calibrate the airflow reading but then realised that the flow rate is not actually what I am interested in. It is the cooling effect the airflow has, which is what I […]
