Computer Application Designed for Arduino Camera tracking system:Дim web As Capture = New Capture(0) ' camera number Then using if conditions we control the motors accordingly.

#Arduino camera projects serial#

While(Serial.available() > 0) // if we have received data or a command from the image processing application, then simply read the serial port and store the received character in variable received. All the motors are set to OUTPUT using the pinMode function and keep all the motor off by defaultвЂ¦then starts the void loop function. Serial.begin(9600) // activates the serial communication while 9600 is the baud rate. While the trigger motor will be controlled using the ArduinoвЂ™s pin number 13.ДЄs the image processing application will send the control commands serially to the Arduino so we will need to activate the serial communication. As the h-bridge has two relays, so one relay will be controlled using the ArduinoвЂ™s pin number 7 and the other relay will be controlled using the ArduinoвЂ™s pin number 8. I started off by defining pins for controlling the h-bridge. If(received = 'c') // HUMAN FACE ON front signals from computer for the left and right movement of the machine gun and trigger.ДigitalWrite(hmw1, LOW) // STOP ALL MOTORS

data from computer, as per the image processing. Int trigger = 13 // machine gun trigger motor connected here For the practical demonstration watch Video tutorial given at the end.Дownload Proteus H-Bridge Simulation: h bridgeДЄrduino Camera Tracking Controller Programming: This H-bridge Module will be used to rotate the platform on which the machine is fixed. Then I tested this circuit using Proteus simulation software. I have also used the same h-bridge in the tongue controlled wheelchair. The relays normally open, normally closed and common contacts are connected with the dc gear motor in such a way that by turning on and turn off the relays the motor direction can be controlled. As you know in the circuit diagram above, an h-bridge is used to control the direction of the dc motor. I selected 2n2222 NPN transistor because it has a low price, easily available in electronics shops, you can think of the 2n2222 NPN transistor as the cockroach of the electronics world. You can use any NPN transistor so far its collector current is greater than the relay coil current. The relay coil resistance can be found using the digital multi-meter and then using the ohmвЂ™s law The selection of the transistor depends on the relay coil current needed to energize the relay coil.

#Arduino camera projects driver#

The driver simply consists of the 2n2222 NPN transistor and a 10k resistor. This relay has total of 5 pins, two coil pins, common pin, normally open and normally closed. This relay is of the type SPDT which stands for the single pole and double throw. This gear motor is controlled using a 12v Relay. The machine trigger is controlled using a 12v gear motor. LetвЂ™s start with the toy machine trigger.

If you want to learn how to make a schematic and PCB then watch my tutorial. This is the complete circuit diagram designed in Cadsoft eagle 9.1.0 version. I would appreciate your support in this way!Д¬ircuit Diagram of the Arduino Camera Tracking System: I may make a commission if you buy the components through these links. This tutorial coversДЇor the step-by-step explanation watch the video tutorial given at the end of this Article. So in this tutorial, I will only discuss the changes.

#Arduino camera projects code#

I did a very little change in the code which I used in version1. Because in this tutorial, I will not explain the things which I have already explained in Version1. So for the best understanding I recommend you should first watch my previous tutorials and then you can resume from here. Arduino Camera Tracking Tutorial is entirely based on the version1 which is the human face recognition and entrance control system, which is a pretty long tutorial covering the EmguCv installation, EmguCv settings which is the most important step, relay circuit making and application designing.
