hi, i am a totally new in microcontroller but i am interested in learning it. so i m planning to carry out my first project, ie to control the speed of a 12Vdc motor using a PIC16F877A microcontroller. i understand that i need to have a programmer to program the microcontroller. where can i get the schematic for bootloader? how do i determine the current i want during no-load and full load? that means i need to calculate the value for the resistors? anybody can share with me the schematic circuit to do the speed control dc motor by using h-bridge with microcontroller as kickstart since i am totally dont know about it. hope somebody can help me... thanks in advance!! =)
