Stepper Motor Interface to Microcontroller

CONNECTION :There are actually many ways you can interface a stepper motor to your controller, out of them the most used interfaces are:Interface using L293D - H-Bridge Motor DriverInterface using ULN2003/2004 - Darlington ArraysWe will dicuss both connection techniques one by one. The above mentioned methods need 4 controller pins for interface.Connecting Unipolar stepper...

PIC and EEPROM Programmer

In this project we are building a JDM programmer that can handle PIC12, PIC16 and PIC18 family microcontrollers and some popular 24C family EEPROMs. The programmer also provides ICSP feature that allows In-Circuit Serial Programming.  So if you desire, you will not have to carry your MCU each time when you reprogram it. The circuit is connected to the PC via serial...

ATmega 16 problem PC2 to PC5 always high

I have about 5 atmega 16 microcontrollers with PC2 to PC5 pins are always high even if i programmed them as outputs and make PORTC=0x00.this problem occurs when the JTAG interface is enabled in ATmega 16.To get rid from this problem you have to disable the JTAG.Here I disablled the JTAG interface using the avr studio and STK500 board.Steps : 1- Connect the STK500 board through...
