//A rising pulse from Rotary Encoder activated forward(). AttachInterrupt 0 is DigitalPin 2 on most Arduino. attachInterrupt(0, forward, RISING); //B rising pulse from Rotary Encoder activated ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Every engineer and hobbyist nowadays has a workbench for all of their tools and gadgets, and if you're a 3D printing enthusiast, you've probably used the vernier calliper a lot. This emphasizes the ...

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the ...

“Measure twice, cut once” is great advice in every aspect of fabrication, but perhaps nowhere is it more important than when building a CNC machine. When precision is the name of the game, you need ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...
