DIY Arduino Powered Diversity
All necessary materials have been gathered to work on an Arduino-powered diversity controller. The design aims to support two inputs, although the hardware can accommodate up to four inputs, and features four amplified outputs. The diversity function will utilize Received...
Pwm Motor-Drive Circuit Circuit
This circuit will drive a small DC motor over a wide range of speeds without stalling by controlling the duty cycle of the motor, rather than the supply voltage.
The described circuit utilizes pulse width modulation (PWM) to effectively control the...
H2 PWM Generators
The Generator cell must have reasonable surface area on the Plates to generate a reasonable amount of Hydrogen/Oxygen. And a Typical construction would use Stainless Steel for the Electrodes to prevent them from being Quickly eaten away. More: DANGER: Hydrogen...
Switching inverter for 12v systems
This PWM control circuit generates control pulses for the DMOS power switch in the flyback circuit. The PWM output produces a pulse width that is proportional to the input control voltage, with the repetition rate governed by an external clock...
Water Level Sensor with Arduino Ethernet
This project implements a network-connected water level sensor that measures the water level in the sump pit of a house. It is connected to the home network and reports the water level by broadcasting UDP packets, allowing any computer to...
PWM to vary the light intensity of a 220V bulb
A 220V bulb is connected such that one end of the relay is linked to a 220V DC source and the other end is connected to ground. The switching between these two points is controlled by a PWM output as...
clock driver for sparkfun easydriver breakout
This project involves using an EasyDriver stepper motor driver and a 1.8-degree per rotation stepper motor to achieve a motor speed of one revolution per minute. The EasyDriver simplifies the operation, requiring a DC voltage of 7-30V connected to M+...
Arduino controlling a DC Motor
When controlling motors with a microcontroller, the snubber is quite important. This configuration is not commonly seen, as the snubber is typically placed across the motor itself. The general concept is that charge builds up on the motor coil, and...
Pulse Width Modulation
The control of electric motors is a topic of interest for those involved in Meccano model building. Each model has specific motor requirements concerning available space, motor power, speed, frequency of start and stop, and the necessity for reduction gearing....
