Tiny Function Plotter using ATtiny85
https://www.electronics-lab.com/tiny-function-plotter-using-attiny85/
David Johnson-Davies build a OLED display function plotter based on ATtiny85 microcontroller. He writes: This project describes a simple routine for plotting a function on a 128×64 I2C OLED graphics display. Unlike most Arduino graphics libraries this routine doesn’t require a RAM buffer, and so will work on any processor down to an ATtiny85: The […]
Heart-rate monitor on a small OLED display with MicroPython
https://www.electronics-lab.com/heart-rate-monitor-small-oled-display-micropython/
By Martin Fitzpatrick @ martinfitzpatrick.name show us how to build the micro display heart-rate monitor. Pulse sensors have become popular due to their use in health-monitors like the Fitbit. The sensors used are cheap, simple and pretty reliable at getting a reasonable indication of heart rate in daily use. They work by sensing the change […]
Tiny Graphics Library for ATtiny85 and SH1106 OLED Display
https://www.electronics-lab.com/tiny-graphics-library-attiny85-sh1106-oled-display/
David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128×64 OLED display using an ATtiny85. This small graphics library provides point, line, and character plotting commands for use with an I2C 128×64 OLED display on an ATtiny85. It supports processors […]
Displaying Customized Graphics on OLED display using Arduino
https://www.electronics-lab.com/displaying-customized-graphics-oled-display-arduino/
One thing we all always wish we could do when using any display is to load our own custom graphics, be it a logo, gif etc. In today’s tutorial we will show how to do just that on an OLED display using an Arduino. OLED (organic light-emitting diode) display is a display based on light-emitting diode (LED) […]

https://www.electronics-lab.com/evscope-reaching-stars/
Humanity has always been trying to reach for the stars, this lead to huge scientific developments that got the man into the moon, rovers into mars and a lot more. NASA often unveils photographs of space objects with bright colors and high definition, but these photos are taken using millions of dollars in telescopes and […]
Arduino Breathalyzer Using MQ3 Gas sensor and OLED Display
https://www.electronics-lab.com/arduino-breathalyzer-using-mq3-gas-sensor-oled-display/
A breathalyzer is a generalized trademarked name for devices used for determining blood alcohol content from a breath sample. This means the device can detect from your breadth, the amount of alcohol you have taken. This device becomes very useful when you consider several cases of accidents caused by drunk driving. With this device, you […]
