Shit last update was 12/26 which means I had 2 months off the electronics track. I gotta find a way to cycle through electronics sessions more often. At this rate I’ll never get to rover control.

Progress. Now I know how to get some lurid blinking going without using up a lurid number of pins. 3 pins to control 8. Soon, 1 ring to control 19.

Didn’t work initially, some of the leds weren’t working. After laboriously testing them, discovered the 74HC595 shift register chip wasn’t seated properly across the gutter (?) of the breadboard. Had to prise it off and reseat. In general the mechanical assembly part is fiddle.

So far I haven’t tried designing my own circuits or writing code. Just doing the tutorials and editing code samples. Yellow-belt stuff. I need to set myself a series of green-belt to brown-belt exercises pointed generally in the direction of the black-belt projects I want to do.

Made slight mistake connecting power between 3v and 5v instead of ground and 5v. I’m getting better at diagnosis. Only took a few seconds to look in the right place for the error. Fortunately not a damaging error. There seem to be few irrecoverable errors in basic Arduinoing.

Need better ergonomics. I get a slight headache every time I do electronics, even with reading glasses and magnifying glass. It’s like 3x the strain of simple laptop or phone use.
