Is This Correct?

Question

Why are you using a mp3 player with your ezb4? You already know the ezb4 has a built in speaker so you don't need a mp3 board... Use the EZB4 soundboard control instead....

Hey @nomad18.08, don't be discouraged! Ask as many questions as you need. I think people might be a little overwhelmed lately since there is so much going on and the forum is moving at the speed of light! But I hope nobody's being cold to you. We're all best friends right? I'm always amused by your posts and your enthusiasm is fantastic. I just want you to keep it up! Maybe it would help if you can explain your problems and situation more clearly?

Without watching the video (as I am unable to right now) I would have thought that the plug is in around the wrong way. There is no real reason that I can see as to why the signal would connect to ground and ground to signal. Not to mention you cannot physically plug some accessory cables in backwards. Don't just watch the video, find the instructions to the MP3 board and see what it says too. I am sure there will also be a forum post regarding this board too if you search for it. As for the Ping sensor which you were looking at soldering. Simply use 2 accessory cables, snip off the one end (not the end that attaches to the EZ-B but the other end). Then on one of them snip off the red and the black wires so you only have the white. Now solder the red wire on the one cable to the Vcc of the module Solder the black wire on the cable to the gnd of the module Solder the white of the same cable to Echo of the module Solder the other white cable (on the extension with just the white wire left) to the Trig of the module. Connect up to two digital ports. Set the ping control port numbers as required and off you go. There is a video for this too, check EZ-Robot's Youtube Channel for it.

Nomad, if you do this, be sure to use a voltage regulator to bring the voltage down to 5 volts. If not, you will release the magic smoke because the v4 doesnt regulate power on the digital ports that this device uses.

o boy glad you warn me.a voltage regulator what that do you have a drawing. where to put it. thank you d.cohran

CochranRobotics · Answer

red wire from EZ-B connects to VIN pin. black wire from EZ-B connects to GND on same side as the VIN pin Red wire from device connects to VOUT pin black wire from device connects to GND pin on the same side as the VOUT pin. I will send a picture as soon as I can.
