Hi my name is Dani, I'm from spain and I'm studding for a degree on electronics, but I always love robots, and now I'm trying this amazing board. I just build my first robot whit this board. I'm controlling 4 motors whit the H-bridge, 2 servos X and Y axis for camera. Just and easy and fast build. I'm also controlling the robot from a joystick. But when I add the servo for de ultrasonic sensor and the ultrasonic sensor, the boards start failing, now when I connect the ez-board whit the computer and start de radar scan, the led on the board stop working, and auto disconnect from de computer, I don't know what I'm doing wrong, pls help.
The servo for the ultrasonic sensor is connected on the D7, and work whit the horizontal servo (it moves nice). The trigger port on D19, the echo port on D18, and vcc on a vcc port, and ground on a grout port
Thx for the help.
If you need more pics or info pls ask
If I power the servos from the batter directly, the batteries must power 5V, not more?
Certainly we are neighbors! area that you live? I am in Palma de Mallorca.
Not working the Ultrasonic sensor? Connections are bad? Or what happens?
Thanks for the help
You can try to start the radar if not servo assigned to your port or disconnected from ez-b, so we can dismiss the error between the servo and the sensor.
But likely ultrasonic sensor is broken? It's new.
I try to buy a new ultrasonic sensor?
A lot of thanks for the help
You may want to check the wires going to the sensor. The terminals might have bent and they are shorting out, or it might just be wired incorrectly.
Ensure no shorts. Most do this by using heat shrink sleeving over the pins on the sensor.
Thanks to all for the help
I hope I can put a video of the robot son
Also ensure you haven't shorted the underside of the board on anything.
D18 and D19 should work fine.
Really thanks to all
