CodeBug at code club




These little devices provide something different to a code. To see the coding interface go to http://www.codebug.org.uk/ (or see figures 1 and 2) and click on create.



Last two weeks
Week 1 
The code clubbers initially shared machines, playing with the CodeBug environment, practice downloading to the bug, writing a routine to scroll their short message. The challenge was then to develop a routine to have a smiley face and a grumpy face scroll across the screen.


Week 2
All have access to the simulation and code generation on codebug.org.uk but this time they don’t have the CodeBug each, they have complete a challenge and run it on the simulation before get a CodeBug to try it. This week's challenge was to get the smiley and grumpy face from week 1 to be selected via the buttons (A and B) - so it involved a loop and conditional statements. Most of them picked it up very quickly.

Two version were built - I reconstructed the ideas in figures 1 and 2 (the code clubbers often did a better version than mine shown here!).

Figure 1: Simple Scroll
The one shown in Figure 1 works by pressing A -scrolls :-) and B - scrolls :-( . Some spotted that the the 'nose' wasn't quite in the place. Some went and found the build sprite block and used that instead.
Figure 2 - Using the build sprite.




Lessons learnt
  • Give them all access individually to the CodeBug website but not to the physical CodeBug straight away
    • They are often a limited resources
    • There is a great temptation from the code clubbers to focus on download to the actual device when the seem to get more done if the spend more time with website and its simulator first;
    • When they have something interesting to put on the ‘bug’; then they can borrow a bug and try it out.
  • They should do a bit of show and tell.

Micro:bit, Servo control with Micropython or blocks

You can control servos (small ones) from a Micro:Bit directly. Following a link from the David Whale (Twitter ) , thank you, took me to a Kitronik blog post, https://www.kitronik.co.uk/blog/using-bbc-microbit-control-servo/, which has the answer.

The code uses Microsoft Blocks taken from the post, runs the servos 180 degrees and back again, when button A is pressed. It does exactly what it should. I am also using the Tower Pro SG90 servo.
Can it be replicated in Micropython? This is a new mini project, there seems to be little out there yet on how do this but the best so far is this video by PHILG2864:



The closest I have is the following, it is essentially there.
from microbit import *
pin0.set_analog_period(20)
while True:
    pin0.write_analog(180)
    sleep(1000)
    pin0.write_analog(1)
    sleep(1000)

Setting the time period to 20ms  pin0.set_analog_period(20)seems by experiment (and used in the video above) to be best value so far. The reason for pin0.write_analog(1)  set to 1 i…

mbots - graphical programming and Arduino

Makeblock (http://mblock.cc/mbot/) funded through Kickstarter the development of a new robot - mBot (https://www.kickstarter.com/projects/1818505613/mbot-49-educational-robot-for-each-kid) with the subtitle "$49 educational robot for each kid". What they came up with is a interesting system that uses their mBlock software, which resembles Scratch but produces code for Arduino, to program a robot with LEDs, light sensors and buzzer integrated on the main board; but also comes with sensors for line-following, ultrasonic sensor and with the version in the kickstarter reward a 16x8 LED matrix.

My impression so far it is really quite intuitive to work with, in the example above the robot:

moves forward;displays 'f' on the LED matrix; turns right;displays 'r' on the LED matrix;repeats until the on-board is pressed to stop the motors. 

What I like most though is seeing the graphical code turned into Arduino code - the potential to see the same thing done into two ways…

4Tronix Bit:Bot Neuron Controlled Edge follower

In thelast post I was playing with 4Tronix'sBit:Bot. In this post I will show the initial experimentation with an artificial neuron controlling the Bit:Bot to follow the edge of a line (it follows the left-hand side of the line).


The neurons (well two separate ones, S1 and S2) are produced using weighted sums - summing the weights x inputs [ right-hand sensor (rs) and left-hand sensor (ls)] plus a bias for each neuron in this case w[0] and w[3].







    net=w[0]+w[1]*rs+w[2]*ls           net2=w[3]+w[4]*rs+w[5]*ls

  If weighted sum >=0 then its output 1 otherwise 0 if net>=0:          s1=1     else:         s1=0
    if net2>=0:         s2=1     else:         s2=0
What actual causes S1 to be either 1 or 0 is all defined by a set of weights w (three for the first neurone, S1,  three for S2).
w=[0,-1,1,-1,1,-1]


Converting the outputs of the two neurones S1 and S2 into actions is shown below.
