In this video Simon shares his idea on the use of the EMG SpikerBox module (from the LittleBits Bit Lab) that detects the electrical activity of human muscles non-invasively using simple skin surface electrodes. EMGs can be recorded from large muscles, or individual motor action potentials ( “spikes”) from smaller ones. Simon suggests using the EMG module as an exercising aid.
We have also watched the EMG video tutorial to learn more about how human muscles work and looked triceps and biceps up in the encyclopedia. Simon was excited to hear that our movements are also guided by electric impulses!
Simon is fascinated by the prospective to develop his own hardware. This video is just a tiny piece of a “lecture” on the LittleBits proto modules and breadboard he gave me yesterday at the park.
Simon was experimenting with changing sound frequency using infrared light today. The light sensor in his electric circuit reacts to any light, including infrared light.
Different remote controls resulted in different output:
When Simon wants some rest from the brainpower consuming Arduino he switches back to the simpler LittleBits. This is just one of the many little things he built over the past week, a motor triggered by light:
In this video Simon explains the use of the LittleBits proto module (a module that can be worked on to make your own new module) using a graph he made himself after watching some tutorials about the proto module. The graph is his summary of what he learned in the videos (his way of taking notes).
This is a beautiful example of Simon’s first daring steps to create his own codes with Arduino. He wanted to make the computer (the serial monitor) say “Yes” once the dimmer was on, then say “No” and then “A Chance”. He tried using switch() case statements instead of if() else statements, but didn’t know about the word “switch”, so he wrote an if() case statement which didn’t work. I googled it for him and corrected the code to my best knowledge (the “Yes” worked within the switch() case statement and the “A Chance” as default, but we didn’t get the “No”to work). Simon was happy to see most of the project work but still seemed to be more interested in the process of writing it than in actually seeing it function.
