Arduino Based LED Chaser using Rotary Encoder

In this project we are going to interface a ROTARY ENCODER with ARDUINO.  ARDUINO UNO is an ATMEGA controller based development board designed for electronic engineers and hobbyists. In ARDUINO we have 20 I/O pins, so we can program 20 pins of UNO to be used as either input or output. A ROTARY ENCODER is used to know the position of movement and angular movement of a motor or axis. It’s a three terminal dev ...

New Rotary Encoder

The Company AMS AG has introduced the non-contact AS5601 Hall-based rotary magnetic position encoding chip. It works by sensing changes in the magnetic field components perpendicular to the surface of the chip and converts field changes into voltages to produce incremental A/B outputs and absolute position information that can be read over an I²C bus. Analog signals from the built-in Hall sensors are amplif ...

LED Calculator with Rotary Quadrature Encoder for Target System Voltage Selection using Arduino

I’m still working on the LED calculator (original idea and most recent work) — I’ve finally got ’round to adding a rotary encoder to set the target system voltage. Now you can turn the potentiometer to set the LED brightness, turn the rotary encoder to set what voltage will be used in the ultimate LED circuit, and read the LED voltage, current, and current-limiting resistor values off the screen. I also fou ...
