In this post, I am discussing using a recently bought CBIS BBC micro:bit RobotArm, but play with it using Python (or rather micropython).
Not a lot to set up really. The base and the arm are separate and are attached with four screws (so you will need a screwdriver).
The most difficult bit is the wiring the arm to the circuit/breakout board on the base, but instructions are available through CBiS Resource portal http://portal.cbis.education/teacher/hardware. You will need a log-in for this. Also on that site, there is an example Microsoft Blocks code which includes some instructions on inserting the microbit as well - the micro:bit goes in buttons side facing upwards.
Taking the values from the instruction sheet for setting it - the micro:bit key bit - the following pins were selected.
Base Pins 0 and 1
Shoulder Pins 8 and 12
Elbow Pins 2 and 13
Wrist Pins 14 and 15
Gripper Pins 16 and 11 - this is the only one I haven't got working yet.
So to test it out, a simple bit of code to drive each motor in both directions was produced and is shown below.
This is good fun to play with. The use of the micro:bit is a good idea because it's ease of use to plug-in and play with.
