This motor driver circuit can drive a brushed DC motor with up to 250W of continuous load. The project can be controlled with the general logic IO-Ports of any microcontroller. Either an Arduino Uno or another microcontroller can be used as the control board. The project uses two IFX007T...

This is a high-performance, adjustable constant current, and PWM dimmer project. It provides accurate output constant current and PWM control. The circuit regulates the current flowing through a LED/LED array to maintain the desired level of light output.  The board consists of...

Plotsensor LTD, an electronics company located in the United Kingdom, has launched a crowdfunding campaign for its compact device that sends environmental sensor readings via NFC. While other sensors connect and send data to the cloud, this battery-powered cuplTag NFC sensor tag sends...

MEMS Microphones is setting a new performance benchmark across a growing number of industries. These innovative silicon microphones were designed to extend the benefits of the lowest possible self-noise (high SNR) and lowest distortion to an ever-expanding number of applications. The...

This project provides AC voltage zero-cross timing detection and a DC voltage after diode rectification with high accuracy. Possible applications for such circuits are AC motor controllers, AC lamp controllers, AC Dimmer Controllers, Home Appliances. The circuit outputs a zero-cross...

This is a dual-supply precision full-wave rectifier board that can turn alternating current (AC) signals into single polarity signals. The OPAMPs, U1A, and U1B, buffer the input signal and compensate for the voltage drops across D1 and D2 allowing for small signal inputs. This...

The circuit shown in the schematic below is a typical implementation of a 12 V - 120 mA non-isolated power supply that can be used in appliance control such as rice cookers, dishwashers, or other white goods. This circuit may also be applicable to other applications such as...

Nowadays, almost all applications and devices provide speech recognition functionality, this makes the device look smart and user-friendly. Cloud plays an important role in integrating such features in hardware systems. But it increases the cost due to additional wireless components and...
