Homebuilt ROVs Forum

My first electronics project was with an arduino and PS2 controller to control motors for an rc rock crawler about three years ago. That evolved into using some bilge pumps from a boat and a motor controller shield for an arduino to begin building an ROV. From there the hacking began. For ROV, this ...

I seem to recall that a servo needs a PWM pin to run. It's been a while..

Pin 2 is NOT PWM, so if that is the servo that doesn't run, use another pin that has "~" next to it. For an uno that would be 3, 5, 6, 9, 10 or 11.

100' of cat5 cable.

Two wire (or whatever its called) worked for me. Just connect the grounds between the two arduinos, then connect rx of arduino 1 to tx of arduino 2....then tx of arduino 1 to rx of arduino 2. Make sure to disconnect this circuit when uploading new code to the arduino. Then you just need to code in y...

For mine I simply used "x" for forward and "o" for reverse. Without using the stick both right and left thrusters move forward (RTF / LTF) or reverse (RTR / LTR). Throw in the analog stick for steering and you'll see the math function below for how this works. On the extremes, fo...

Here’s my code, it still in development, but it works. I’m planning on using a PS2 controller to transmit controls hooked up to an arduino, and use that arduino to send a serial data stream to the aruduino on the ROV over a Cat5 cable. Three strands of the cat 5 cable are needed to have the two ardu...
