Hacks and Mods: Tweeter Used to Sense Vibrations

Schematic Diagrams      Comments Off on Hacks and Mods: Tweeter Used to Sense Vibrations

The creator built a neat looking project which uses a piezoelectric element from a tweeter to detect vibrations. He is using a Zilog eZ8 series microcontroller which seemed to be very popular years ago. This project dependently using a strong vibration while the enclosure has been placed on the top… Read more »

Hacks and Mods: Arduino Based Capacitive Touch Screen

Schematic Diagrams      Comments Off on Hacks and Mods: Arduino Based Capacitive Touch Screen

Arduino based projects are quite complicated and is no cake walk for beginners in this field. Interfacing a tablet with the microcontroller is a daunting task. Let see how its done here. The primary focus should be on using the appropriate drivers for the tablet. This makes it a USB… Read more »

Driving CDROM Stepper Motor with Arduino

Schematic Diagrams      Comments Off on Driving CDROM Stepper Motor with Arduino

H-bridge is frequently used to control DC motors and stepper motors. When controlling a bipolar stepper motor, two full H-bridges are needed. There are many H-bridge ICs (like L298, MPC17529 and SN754410 which is a quad half H-bridge) for just that purpose. But if you are on a budget, you… Read more »

1000W AC Motor Speed Controller

Schematic Diagrams      Comments Off on 1000W AC Motor Speed Controller

This triac based AC motor speed controller circuit is designed for controlling the speed of AC motors like drill machines, fans, vacuums, etc. The speed of the motor can be controlled by changing the setting of P1 potentiometer. The setting of P1 determines the phase of the trigger pulse that… Read more »

Two Wire I2C Arduino LCD Display

Schematic Diagrams      Comments Off on Two Wire I2C Arduino LCD Display

In this tutorial you will learn how to build a simple serial 16×2 LCD display that is controlled via Arduino board by only two wires. The magic behind is done by the PCF8574 chip, an I/O expander that communicates with the micro-controller by using I2C protocol. The PCF8574 is a… Read more »

It is, however, most vital for designers of embedded control products to select the most suitable controller and companion devices. Embedded control products are found in all market segments: consumer, commercial, PC peripherals, telecommunications (including personal telecom products), automotive and industrial. Most embedded control products must meet special requirements: cost… Read more »

Arduino RF link using 433MHz Transmitter / Receiver modules

Schematic Diagrams      Comments Off on Arduino RF link using 433MHz Transmitter / Receiver modules

If you are looking into wireless communication between two Arduino modules, this project might be helpful. It uses low costs RF transmitter and receiver from Electronics-DIY.com to establish radio link between two Arduino boards up to 500 ft. Data can be transferred serially at the maximum rate of 2400 bps…. Read more »
