- Topic: Cherokey 4WD Arduino UnoYou Reply: Awesome thank you very much. So I got that working, except now when I go right or left, it makes a high pitch sound and doesnt turn at all. And when I have all the jumper caps on, and I move forwards, the front wheels go backwards, and the backwheels go forwards making it just sit there. With all jumper caps off, it moves forward and back, except slowly cause its only using the back wheels and it will not turn! LOL I'm having the worst of luck!
And final question once this works: How do I get the bluetooth working? https://www.dfrobot.com/index.php?route= ... l-srXarSCg
That is my bluetooth and I'm wondering how to use it via Arduino sketch. I have no idea how to get it functioning besides pairing it to my pc. Outgoing being com4, and incoming being com3. - Topic: Cherokey 4WD Arduino UnoYou Reply: For some reason when I remove the jumper caps from the motor selection. The motors begin to work. But that is just supposed to be for having each motor independent. I dont understand why they dont work the jumper caps on, when the purpose of that is supposed to have the motors follow the same commands.
- Topic: Cherokey 4WD Arduino UnoYou Reply: Okay so the input is working. I got the baud rate correct, thank you for that. When I press "z" it prints hello. And when I press "w" the lights dim a bunch but nothing else happens.If I press anything other than "w" the lights pretty much dim off completely or until almost no light comes out. Am I missing a wire to be connected? Each wire is hooked into the wheels, but not soldered ( which should not affect anything). I am using 5 AA batteries as that is what it came with. Here are some pictures of the wires going in and soldering.
Am missing any wires to go anywhere? Or are my 5 AA's maybe not giving enough power? - Topic: Cherokey 4WD Arduino UnoYou Reply: @Leff I will check all that tonight when I arrive home, thank you very much for the help.
@Maht:
It is connected to those pins, and soldered on. I am using the instructions given by the wiki dfrobot page.
It is connected to the computer when sending commands, but I might be using the wrong lines, will check to see if it works as suggested by @Leff.
There is the seperate power source of 5 AA batteries powering the whole module. The LED's do power on, and the arduino works and is powered perfectly by those batteries. I also have a rangefinder and a speaker, and a robotic arm all attached which work perfectly when connected to the arduino which is connected to the 5 AA batteries.
I have tested it without having the arm or rangefinder connected, but no go.
Ill check to see if wiring is wrong tonight. Thank you for your fast responses.
