Hi
I have a GoPro 8 which I switch on automatically with a controller when I'm filming secretly for my YouTube Video Blog. But I wanted to be able to turn the camera 180%, (90%) in either direction on a tiny revolving disc powered by a small Micro Servo.
I've got a copy of the latest Blynk on my phone and can connect to the Arduino but I've yet to find a suitable sketch to run it. All that I need is to send the GoPro 90% to the right of center or 90% to the left of center.
If anyone knows what I'm trying to achieve I'd be grateful for any help you can offer.
Hallo mark
That's what I was thinking but I've tried to take a kid's rc car apart before and I'm sure the manufacturers don't want anyone "looking under the hood" so to speak. In the end, it went to landfill in my recycle bin. There were hardly any screws and the ones it did have had been super glued into place. You can imagine the plastic shards all over my wife's kitchen. My ears are still ringing.
I have seen a video about using an L298P Motor Driver Module That sits on top of the Arduino to drive the Micro Servo which looks promising but I'll have to search for further information on one of these before I purchase it.
I don't know if those cheap RC cars have what you need. Here's a UK website that deal with lots different servos for RC models (land, air, water based etc):
Those are the sort of devices I think you should be using. Note that if you do use an RC servo, then all the motor drive electronics is already inside the servo, so you don't need any additional motor drive module. You just need to provide the PWM digital signal from one of your Arduino pins to control its position. See this tutorial:
The sweep example looks to be a good starting point.
You had a bad experience with a "toy" grade rc. Hobby grade rc cars are totally customizable, servos are cheap as chips or can run into hundreds of dollars. Good news: you only need a cheap one. Any for a steering servo for a 1/16 scale car or a micro servo for an rc airplane will do. Then just use the servo library. Just be sure to power your servo from a separate 5 volt supply, the one on the Arduino is not recommended for +5v on a servo (red, usually). Then connect yellow (usually) to the digital Arduino pin, tie the +5v supply /battery ground to Arduino ground
