With this project you can control a unipolar stepper motor. You can control both the speed and the direction of the motor. The speed and direction and can changed with help of the keypad. The data’s are displayed over the LCD display. A 4×4 keypad is used for entering the speed and selecting the direction. Load the hex file …
For measuring motos speed there can Optical interrupter used like H21A1. This is a device where IR LED and photo-transistor is coupled in to plastic housing. The gap between then allows interrupting signal with opaque material and this way switching the output from ON to OFF. This device can be connected to Microcontrollers ICP pin …

Using graphic LCD in a project gives it really a good look and flexibility of displaying different characters and shapes. But, the graphic LCDs are quite costly. The NOKIA 3310 LCD provides a really low-cost solution to add a small graphic display into your project and also good for learning purpose. The LCD is SPI bus compatible, saving many pins for other uses. …
16×2 LCDs are most commonly used display units in microcontroller based projects. I got much information about LCD, LCD commands, LCD initialization etc from the below link and I hope, it will be very much helpful for beginners. http://www.dinceraydin.com/lcd/intro.htm Below is my final working code for 4 bit mode LCD with PIC16F877A: (HI-TECH C) #include<pic.h> #define _XTAL_FREQ 20e6 __CONFIG(0x3F3A); …

So, you’re going to a conference/meetup/nerdfest and you want to do something that sets you apart from normal people. An LCD namebadge powered by an ATtiny2313 is a great way to do that. This is a general purpose LCD display unit powered by a 9V battery and a simple voltage regulator circuit (the same 7805 circuit you see absolutely everywhere). It’s no-frills, but …
Hi techies!! This is one more of my circuits, interfacing ATmega32 with an LCD and a DAC. it also includes two general purpose push-buttons and In System Programming connector. The controller is operating with 14.7456 MHz frequency crystal, convenient for generating standard baud rates (for RS422 communication whic i used in my actual project, not …
