Output Devices

Designing

This week we were told to add an output device to a microcontroller board and program it to do something. Because my final project is a motorized camera slider so i will use stepper motor so i need to make a stepper driver so i copied niel's design and code to help me fabricating my board. I added power jack and 2 extra input pins because i wanted to add buttons to control my motor later on.

After soldering the board i found out that i havent connected the LSS Pin of the h-bridge chip to the ground so i shorted it with jumper wires and soldered 2 smd leds to the motor pinouts to check the signal.

After finishing the board i tested it with niel's code.

After i tested it i fixed the connection problem and changed the ftdi header to 4 pin headers (VCC,GND,TX,RX) because i am going to use a bluetooth module in my final project to control the camera slider.

After finishing the board i tested it and it worked perfectly.
