Okay i'll play around with the value. But I havent connected my OpenMV Cam to the pan and tilt yet. Im running the Pan and Tilt without the camera. First testing relays, but thats when the transformer gets hot. As soon as i can get the relays running in NC i'll hook up the OpenMV Cam. ,Sleepy Engine...

Okay i'll give that a go.. When the pan and tilt gets power, it moves.. but as soon as i hook up a normal closed Relay, it gets the transformer overheating. When i connect it in Normally Open, it does nothing, because i cant switch the coil of the relay, so the pan and tilt moves on its own, counter...

Circuit is working, only problem we're having is the circuit is drawing too much current. ANY Ideas to how this can be solved? Our transformer gets hot and starts smoking, the rating on the transformer is 4A at 24VAC.

Kind regards,
Sleepy Engineering Student.

Thank you so much for the assistance on the project. Will upload a video to youtube soon, if Im allowed to put OpenMV on the web. Full credit will be given to OpenMV. In the final testing stages and handling the fact that our circuit is drawing abit too much current. Kind regards, Seeing light at th...

Got it triggering.. Turns out I cant source from a 9V Battery. I need to use a constant DC voltage from a power supply.. I attached the circuit Im using.

http://www.instructables.com/id/Design-a-Sustainable-Relay-Driving-Circuit-Using-B/ I used the above circuit. With a 1k Resistor.. But for some reason when i rebuild the circuit. The relay switches once and not again, Im using a 7V battery as the VSS and 3.3 as the input at v1. I have the 2N2222 Tra...

Okay Im going to have to Amplify the signal being sent from the OpenMV Cam (3.3V and 0.05A). Hoepfully I'll be able to get it to the desired 3.3V and 0.08A. Thanks. This is the last part of the project, then it should work 100%. Will upload a video as soon as its done. Kind regards, Sleepy Engineeri...

Ive seen those examples online. Thats where i got the idea for Transistors. But does this example solve the problem of Current? I see the emitter of the Transistor goes straight to ground. and voltage is being dropped before the transistor. Since V = IR, wont I also become smaller because of the res...

It works perfectly. I got 3.3V relays.. the open mv cam outputs 3.3 V which is correct, the relay should trigger, but the current is too small (0.6A). I need it at atleast 0.8A to make the relays trigger. I have to build a circuit that can boost the current of the input that goes to the 3.3V relay. ...

How do i set all pins to 0 if nothing is being tracked on the OpenMV i.e theres no rectangle and cross.

Wow didn't even think of getting a position using the difference in edge to the rectangle. Some clever thinking and then setting the pin HIGH according to those measurements. Thank you. Im going to try and connect a few Relays to pins. The Pan and Tilt will use the 24VAC from Transformer to move the...

Thank you so much.. do you maybe know what 4 pins i can use on the OpenMV Cam? Also how do i make the pins HIGH for framerate? Can you maybe give me an example.. Apriltag tracking is a success. Now i need to trigger the corresponding pin.

Thank you, looked at it.. I have another question; How do i send a 3.3V signal to a relay that's going to be used to actuate the pan and tilt(pan and tilt moves when 24VAC is sent to one of the 6 pins). I want to send a signal to the relay that triggers the pan and tilt device to move. Each pin move...

Hi Im a mechatronics student in my final year. We have a project that tracks colour and outputs it to a pan and tilt device with the following specs Brand LILIN Model Code PIH-301 AC/ DC Type AC Mount Type Top Mount Max Load kg 38 Indoor/Outdoor External Autopan Yes Pan Speed o/ second 6 Tilt Speed ...

Can i maybe have a schematic that shows what pins on the servo shield connects to which pins on the openMV cam

Theres something wrong with the program. Its not outputting to my servo (Pin 7); any help??? # Pixy UART Emulation Script # # This script allows your OpenMV Cam to emulate the Pixy (CMUcam5) in UART mode. # Note that you need to setup the lab color thresholds below for your application. # # P4 = TXD...

As of right now, its just a normal dc motor. We were thinking of using an arduino chip because we arent allowed to use a development board. Only problem is reading the values for x and y in the face detection or colour detection program and outputing it to the motors. is there any way of maybe getti...

We were given an object we have to innovate, its an old pan and tilt device. It uses basic DC motors to change direction in x and y direction. We have to interface that with the openMV Cam.

Hi im currently a mechatronics student. One of our projects was to design a pan and tilt device (Relatively old) using an OpenMV Cam and Arduino uno. The motors in the current pan and tilt uses voltage to trigger certain directions it has to move, it has a separate wire for each of the directions it...
