futz f&ts v.i. To tinker experimentally; to change something just to see what it does

I wrote some code for the PyBoard to drive a TM1637 4-digit 7-segment LED display. The code is basically I2C with no slave, so not terribly difficult to bit-bang.

Then I modified that code to use the PyBoard's RTC to work as a clock. That worked fine, so I thought I would get it going on the Trink...

I've been interfacing the pyboard to all kinds of stuff to get a bunch of coding and practice under my belt before I really try to do something like a robot with it. I've ported my 5110 LCD C code for PIC to MicroPython, and connected things like servos, a HY-SRF05 ultrasonic range sensor, a Sharp G...

I ported my 7110 LCD C code for PIC to MicroPython on the PyBoard. It wasn't very difficult. Yet again, most of the trouble I had was due to having to learn Python as I ported the code. Not a big deal - Python isn't difficult to learn.

I wasn't sure about text formatting for my font array in Pytho...

After tinkering with the Adafruit Trinket M0 for a short while I ordered a STM32F4 MicroPython board from icstation.com. When I got it I dropped it in a box and forgot about it for a year or so. When I finally went to play with the board I saw that it had "TPYBoard" printed on the back, so I googl...

On a recent China order I bought five 16F72 PIC microcontrollers in 16-SOIC for very cheap, thinking I could find some use for them. They sat in a box for a long time. Lately I've finally got somewhat caught up with work and have a little time for electronics tinkering again, so I decided to wire on...
