Here's an animatronic eye mechanism I made using machining tools like a lathe, as well as 3D printing and arduino. Although I ...

Learn how to easily adjust the contrast of a 1602 LCD display using Arduino. In this quick tutorial, I’ll show you a simple trick to control the contrast electronically, without relying solely on the ...

This paper explains the development of a behavioral model of a rotary incremental encoder and its physical implementation using VHDL. The basic characteristics and the behavior of the encoders are ...

A PWM waveform generator with variable duty cycle has been designed and implemented in this paper. The design has been simulated for different frequencies. The waveform is generated on Spartan 3E FPGA ...

This is small and fast Arduino library for Rotary Encoder with interrupts.

The guide show you how to allow your app to record audio from the microphone while other app use it. This way you can use microphone at same time that other apps. To allow this feature you will need 2 ...
