Note: Try any or all of these at your own risk. I will not be responsible for any issues. Get a professional to help if you are unsure. The concept is that we take a controlling voltage from the computer or a micro-controller, which drives an electrically isolated circuit with Relay or Triac. You must …
Interfacing LCD Display in 8bit Mode I’ve already discussed about the LCD display in a note here in this website. You can read the Note on character LCD Display here. Now let us come to the interfacing side of LCD. Let us see the 8bit mode interfacing of the LCD display with an AVR micro …
To establish a good communication between human world and machine world, display units play an important role. And so they are an important part of embedded systems. Display units – big or small, work on the same basic principle. Besides complex display units like graphic displays and 3D dispays, one must know working with simple displays …
Well this is not different from the way interfacing the LCD to 8051 or PIC microcontroller. The crystal oscillator will provide the clock to the microcontroller. The capacitors connected to the crystal will act as filters and help the crystal to resonate and oscillates to its parallel resonate mode. The potentiometer which is connected …
In this article I will describe how to interface a Ultrasonic Range Finder Module with a AVR ATmega8 microcontroller. I will provide a HEX file which you can burn into your ATmega8 directly to quickly test this whole setup. Ultrasonic range finder modules helps find the exact distance to an object. This can have vast …

This article would give you a general idea about how to setup and interface any Bluetooth modem with your computer. There are many types of Bluetooth modems available in market, which vary in quality, cost, range, etc. Some of the well known Serial Bluetooth modems are AUBTM, BLUESMIRF, RN-41, HC-05 and HC-04. I would be …

Hello friend once again with new instructable in this I will show you how to interface GY 26 with UART when I started working on this very less resource where availble over internet .Thus i thought to share my piece of work .GY 26 is a digital compass which gives angle with respect to earth …
DESCRIPTION This project is to make a clone of Arduino Leonardo in a simple way.That is why the distribution of the pin does not match the standard Arduino (have to make many jumpers on the motherboard or use both sides). However, most Arduino Leonardo characteristics are maintained. The circuit is protected by an automatic reset fuse …

Easy Input is a head-controlled keyboard and mouse input device for disabled users. The system uses accelerometers to detect the user’s head tilt in order to direct mouse movement on the monitor. The clicking of the mouse is activated by the user’s eye blinking through a reflective sensor. The keyboard function is implemented by allowing …

Driving a shift register using an AVR chip’s built-in hardware is really quite easy. Most of their offerings have an SPI module, or Serial Peripheral Interface. A shift register is exactly that, a peripheral device that communicates via a serial line. All we need to do is hook up our connections and use a few …
