The arduino nano sends the waveform type and frequency via SPI to the AD9833, that generates the requested waveform. While doing this, the OLED display (SSD1306) is updated by the arduino via I2C, ...

This project is a DIY simple optical rotary encoder with 180 points per rotation and bi directional detection that you can make at home with a 3D printer. This Arduino Rotary Encoder is intended to ...

It is fairly easy and straight forward to program the Arduino board for interfacing a Rotary Encoder with it if you had understood the working principle of a Rotary Encoder.

RT & Arduino experiment was successfully conducted at my own lab using the ALPS-EC11E RT and Arduino UNO-R3, ported with a sketch borrowed from the web. You may ask why I did not prepare my own sketch ...

At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, and 16×2 LCD providing an interface to control it over SPI.

A measuring wheel is a construction measuring tool. The wheel rotates and, using basic rotational kinematics (s=rθ), you can determine the distance between two points. The video below shows a reduced ...

In this article we are going to building a simple Signal Generator with Arduino and AD9833 DDS Function Generator Module which can produce sine, square, and triangle waves with a maximum frequency of ...

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 ...
