CO2 Monitoring As an Anti-Covid19 Measure

“Here, we propose an open-source, portable, autonomous, cheap and easy-to-use device to monitor and record the concentration of CO2 in ambiant air in real-time. Using CO2 as a proxy for respiratory aerosols, the device can help define best practices regarding …

Create Custom Animations on 16x2 LCD Displays

“Easily display custom animated glyphs on 16x2 LCD using the createChar() function from the LiquidCrystal library. The LiquidCrystal library makes it easy to use LCDs with Arduino. A particularly interesting function from that library is the createChar() function: you can …

Getting Realtime ECG on OLED Screen

“I made an Arduino library allowing simple communication with uECG device using nRF24 module - minimal example takes just a few lines. Some time ago I posted a couple of projects demonstrating how to get data from uECG device - but they …

Interfacing Multiple DS18B20 Digital Temperature Sensors with Arduino

“One of the biggest advantages of DS18B20 is that multiple DS18B20 can coexist on the same 1-Wire bus. As each DS18B20 has a unique 64-bit serial code burned in at the factory, it’s easier to differentiate them from one …

Match the Color Game Using 555, 4017 and RGB LED

“I created a circuit in which random colors are picked and where the user must attempt to match the colors as many times as possible for a high score as they blink on and off from left to right at …

4-Wire Horizontal Plotter

“This instructable explains how to make a 4-wire plotter using the wheel-rims from a toy car, four stepping motors, a scrap of sheet aluminium, some pulleys, and an Arduino UNO R3. Unlike 2-wire vertical plotters the drawing surface for this …

ACRO Openbuilds Pen Plotter (Arduino With GRBL and Raspberry Pi With Universal G Code Sender)

“I have had an interest in building a CNC machine for quite a while but having lived in small flats/apartments there have always been barriers whether it be space, noise or dust! This instructable details my build of a …
