DC motor driver for DCMP(AVR-008)
A microcontroller is used to control various types of DC motors, including permanent magnet DC motors, DC servo motors, and stepper motors. This project utilizes the AVR-008 microcontroller from Circuits-Home, which is frequently referred to as the 3-in-1 driver motor...
Miniature Real-time Controller
This is my long history the device that controls my home's night light, air-conditioner, etc. The device is a Miniature Real-time Controller. The circuit uses only three chips, a 89C2051, DS275 (or MAX232), and 74LS07 open collector driver. The scheduler...
interfacing arduino with a telit gm862
The Arduino can communicate over various networks, including Ethernet, Bluetooth, Wi-Fi, XBEE, and GPRS. A Telit GM862-GPS module, which has GPRS and GPS capabilities accessible via AT commands, has been repurposed for use with the Arduino. The GM862's logic pins...
Arduino multi-mode lamp with soft touch switch
This Arduino-based project involves constructing a lamp with various light displays, including a color sequencer, dimming light, color chaser, and firelight, all controlled by a touch bar on the circuit board. The design adopts a minimalist approach, incorporating only a...
Improved Arduino TV-B-Gone
The TV-B-Gone is a compact infrared remote capable of turning off nearly any television. Previously, the TV-B-Gone software was adapted for use with the Arduino platform. For further details regarding this adaptation and its functionality, refer to the earlier post...
Arduino UNO
The Arduino Uno schematic diagram is available for viewing. The Arduino Uno is a microcontroller board that utilizes the ATmega328 chip. It features 14 digital input/output pins, of which 6 can be used as PWM outputs, and 6 analog input...
microcontroller Arduino 230v Light bulb dimming
Have you verified whether you can see the zero crossings on your input pin? It may be beneficial to write a sketch that toggles the LED on pin 13 every 50 or 60 zero crossings. This should result in a...
Motor control with tachometer
The generator output is rectified, filtered, and applied between the positive supply voltage and the base of the detector transistor. This configuration provides a negative voltage that reduces the base voltage as the speed increases. During normal operation, if the...
Real-Time Energy Monitor with Arduino and LabVIEW
The system consists of two components: an Arduino board that detects LED pulses and transmits the data via an XBee module, and a PC that receives the data through a USB/XBee module and processes it using LabVIEW, allowing for real-time...
