The purpose of this tool is to measure any rotation speed with the same accuracy as a commercial product, it can also blink at afrequency defined by the user to match the roatation of anything up to ...

The rotation rate is displayed on an OLED screen. The units can be switched between RPM, rev/s and rad/s by pressing one of the OLED screen buttons. The display will go blank when no rotation has been ...

We’re certainly no strangers to unique timepieces around these parts. For whatever reason, hackers are obsessed with finding new and interesting ways of displaying the time. Not that we’re complaining ...

This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute ...

Nowadays, there are evolving projects in robotics, and many hobbyists are creating their own robots. For these Robots, displays are a vital component of an interactive user interface. If you're ...

From drones to smart cars, from lifts to industrial robotics, all use an important device: a motor or rotating gear. For reliable, robust and efficient motor design, measurement of rotational speed is ...

SCL Serial Clock - The signal that synchronizes the data transfer between OLED and Arduino. SDA Serial Data - The signal used to transmit data between OLED and Arduino. Once you have everything you ...

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...

The Arduino OLED Dice project is a digital way of rolling dice with auto power off function. Aside of a typical push button switch, it uses a tilt switch sensor to start rolling the dice as shown on ...
