Hey!
Yesterday i was driving around with my robot powered by EZ-B when it got stuck in forward (not the software but the ez-b itself) and i couldn't stop it, i rebooted and it got stuck in turning.
Now i powered it up but the Bluetooth module light won't come on, then it finally came on and everything works as normal but the status led doesn't work. not even when i try to turn it on in ARC blush
hey there
The resistors won't affect the LED or performance. Please don't change them
. The first batch of assemblies do have a dimmer LED, but that isn't really an error. It was a different resistor used. One will just be dimmer than the other, .. no big deal.
As for some LED's not working at all, that is strange because Colin doesn't ship any EZ-B's without the flashing status led. Unless he missed some. From what I hear, there may have been some IR LED's in the random pile. Every EZ-B has a random status LED (by my choice). I thought it'd make it fun
.. Check to see if your LED is IR by looking at it through your digital camera or phone camera in a dark room. If it lights blue in the camera, then it's an IR LED haha
As for the bluetooth light stop flashing... It may be due to two reasons:
a) almost 100% of the time that it happens to me it is power releated. The 5 AA battery pack only lasts around 30-60 minutes in my robots. This is because servos draw a lot of current, specifically when they're holding position. The EZ-B will eat up batteries because peripherals are hungry little guys. I purchase a box of 100 AA's from Future Shop from $25 CDN. I go through them in no time
b) on occasion the bluetooth module may unseat itself if it has been removed before. It's connected by a 4 pin plug and it may come lose. At least mine have because they don't have sticky tape holding them on.
