Hi Gordon,
I Have just received my start kit, thank you.
The servomotors and the lights are working very well when I power them via the board ( which itself is powered via USB ), but when I power up them with 4 AA batteries ( which generate about 6V, slighty more than the 4.7V from USB ), they do not respond to controls.
Basically the GND of the board is connected to the "-" of the 4 chained AA batteries, the red wire of the servo/lights is connected to the "+" of the 4 chained AA batteries, and the control wire is B5 or C7.
When the red wire is connected to the board's VBAT, everything is fine, but when the red wire is connected to the batteries, the servo and light do not respond.
What am I doing wrong?
Can I power up the espruino board while it is usb-connected to my PC?
Thanks,
Olivier
