Using AD9835 DDS chip with BASIC-52
The AD9835 is a Direct Digital Synthesis (DDS) chip manufactured by Analog Devices. It comprises a phase accumulator, a sine wave table, and a 10-bit digital-to-analog converter (DAC). This chip can be utilized for both phase and frequency modulation by...
graphical LCDs with a microcontroller
How can graphical LCDs be controlled using a microcontroller? Is there any datasheet available?
Graphical LCDs (Liquid Crystal Displays) are widely used in various electronic applications for displaying complex graphics and text. To control these displays with a microcontroller, several steps...
Electronics Engineering Herald - online magazine of electronics -home
Embedded systems serve as the core of most electronics-based systems, enabling data access, processing, storage, and control. While some simple electronic circuits can be designed without a microprocessor or microcontroller, this approach is often economically impractical, except for basic passive...
Microcontroller-based: Electric fan switching relay or triac
A project is underway to control the speed of an electric fan (220Vac, 60W, 5A max.) automatically using a microcontroller based on certain parameters.
The circuit design for controlling the speed of an electric fan involves several key components to ensure...
Robo Atmega328p project
This project was designed to introduce a friend to microcontrollers and circuits using various functionalities and spare parts. A PS2 numpad was utilized as the key entry mechanism, which was found at a thrift store and included the necessary connector....
Automatic Switch Project
Model railroad turnouts, often referred to as switches, can be controlled in various ways. The simplest method is manual control, operated by hand. Remote activation is typically achieved through pneumatic (air) or electrical means. The project discussed in these articles...
How to Design Battery Charger Applications that Require External Microcontrollers and Related System-Level Issues
Application note on designing linear and switch-mode (switching DC-DC converter current source) battery charger applications that require external microcontrollers and related system-level issues for notebook computers.
The application note provides guidance on the design of both linear and switching DC-DC converter...
10 or more switches using a microcontroller
There are several methods to read multiple switch inputs using a reduced number of microcontroller unit (MCU) pins. One approach involves using an analog MCU pin to read multiple switches by assigning a unique voltage to each switch through a...
Microcontroller Programming 2
For this week's assignment, a chip design was provided, and the task was to incorporate a button and an LED (light-emitting diode). The objective was to fabricate the chip and program it to interact with the light and button. Given...
