Rotary Camera Control with Stepper Motor

13^th Shaban, 1429 AH at Queens, NY.

This project involves a simple stepper motor controller designed to rotate a small wireless camera. The setup is based on the circuit from a previous project, with the main difference being that the camera now rotates in response to Right or Left arrow key presses from the keyboard. Unlike the previous project, where the stepper motor rotated counterclockwise, this setup rotates clockwise by reversing the step sequence.

He is with you wherever you are. For Allah is All-Seeing of what you do.

Quran 54:4

The step sequence for clockwise rotation is as follows:

STEP-1   0001     5
STEP-2   1001     4
STEP-3   1000     6
STEP-4   1010     2
STEP-5   0010    10
STEP-6   0110     8
STEP-7   0100     9
STEP-8   0101     1

For capturing video, I used a wireless camera that transmits A/V signals at a 2.4GHz frequency. The receiver picks up these signals and sends them to a PC via a USB capturing device called EasyCap.

The video capturing application was developed in VB.NET using a third-party class named iCam, which relies on avicap32.dll for working with the video captured by the camera.

Here is a live demonstration of this project:
