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 […]
Nixie thermometer

circuitspecialists.com has published a new guide on how to build your own 8×8 LED Matrix on a prototyping board. In a later guide they will show how to program it using an Arduino Compatible board. Today we will be starting our adventure into the deeply complex, yet totally incredible world of LED Matrices. This post […]
Quick Arduino Hygrometer with OLED display
https://www.electronics-lab.com/quick-arduino-hygrometer-with-oled-display/
jazzycamel @ instructables.com has published an Arduino based Hydrometer with OLED display. It uses an Arduino Leonardo Pro Micro, an Adafruit SSD1306 OLED display and DHT11 digital temperature and humidity sensor. We have been having some condensation and mould issues in our apartment recently due to, I think, the humidity levels. Our property is relatively newly built […]
OpenSource Arduino OLED Clock with temperature measurement
https://www.electronics-lab.com/opensource-arduino-oled-clock-with-temperature-measurement/
Konstantin Dimitrov has published his Arduino OLED clock which uses DS1307 real time clock module and TMP102 temperature sensor that communicate through I2C. This clock will not only show you exact time and date but also it will show you the ambient temperature in both Fahrenheit and Celsius, with accuracy of 0.5°C (-25°C to +85°C) and […]
Home Built Bench Power Supply using ATMEGA328P
https://www.electronics-lab.com/home-built-bench-power-supply-using-atmega328p/
ianjohnston.com has designed a nice power supply based on ATMEGA328P and Arduino bootloader. The output is dual channel 0-24vdc @ 3A each, with preset constant current and independant voltage/current control. This isn’t a full design blog but I’ve tried to document/add stuff as I go along, the idea being I’ll put all design documentation (schematic, […]
How to use the 4.3′ E-Paper display with Arduino
https://www.electronics-lab.com/how-to-use-the-4-3-e-paper-display-with-arduino/
educ8s.tv has uploaded another tutorial on how to use a e-paper display with Arduino. Source code is provided. Electronic paper and e-paper are display technologies that mimic the appearance of ordinary ink on paper. Unlike conventional backlit flat panel displays that emit light, electronic paper displays reflect light like paper. This make them more comfortable […]
