“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the ...

Number of counts (pulses) per full revolution of the encoder knob. Each count corresponds to a small increment of rotation. Which direction is the wheel turning? A positive positionChange indicates ...

A ros node that reads serial data from an encoder for a variable length slung-payload drone and outputs to a topic for further processing. Also can read a command topic to send a serial message to ...

LED3個とスイッチ1個、ロータリーエンコーダのAとBの端子2個をArduinoの適当なデジタル入出力端子に接続します。 使用する端子はどこでも良いのですが、UART、SPI、I2Cのポートは後から使いたくなるかもしれないので、それを避けるように接続先の端子を選びました。

Before you do anything, you have to install some libraries from libraries2.zip. Copy the libraries (directories) from this zip file to your Arduino/libraries directory. If you already have libraries ...

To collect data, we need to find a way to move data from the Arduino to your computer. It turns out the Arduino's memory is too small to hold much data, so collecting the data and sending it after an ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...
