gfwilliams @ instructables.com has build a smart battery charger that is able to individually charge each battery , automatically discharge them and give you an idea of their capacity. The charger is controlled by an Espruino Pico and results are displayed on a Nokia 5110 LCD display. If you’re anything like me you’ll end up […]
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 […]
Starling – WiFi enabled LED Display
https://www.electronics-lab.com/starling-wifi-enabled-led-display/
Starling is a modular, Open Source LED display with WiFi connectivity. It comes with a mobile app for easy configuration and usage and has hardware support for Bluetooth. The LED matrix is driven by an Atmega8 microcontroller (MCU), instead of a standard ASIC. This provides a lot of flexibility in the firmware. The firmware detects […]
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 […]
Wi-Fi and OLED Upgrade for MightyOhm Geiger Counter
https://www.electronics-lab.com/wi-fi-and-oled-upgrade-for-mightyohm-geiger-counter/
Dan Watson @ syncchannel.blogspot.com wanted to have more fun with his MightyOhm Geiger Counter so decided to add an OLED display and Wifi capability to it. To achieve that he modified the counter, added a Feather HUZZAH ESP8266 with OLED FeatherWing and wrote some code. The process is documented on his blog: I assembled my Geiger […]
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 […]
LED Tester with LCD Display
https://www.electronics-lab.com/led-tester-with-lcd-display/
David @ robotroom.com build a microcontroller based LED tester with LCD display that shows the LED voltage, the current limit in mA, the desired led voltage and the calculated resistor value. The LED tester is based on ATtiny84 mcu which performs all the measurements and calculations and updates the display. Build details on the link […]
Remote WiFi DHT11 Temperature an Humidity Display
https://www.electronics-lab.com/remote-wifi-dht11-temperature-an-humidity-display/
BoianM @ instructables.com shows us how to build a remote temperature and humidity display using DHT11 sensor and two ESP8266 modules. To program the ESP8266 modules a visual programming software is used. The advantage of the ESP8266 over Arduino and other controllers is the builtin Wi-Fi. In this Instructable I will show you how with the […]
