Motorfish: The stepper does not misses a step (the Firmware)
Let’s describe the firmware of the stepper motor feedback controller and test it on the 3D printer. (Read the first post) In the limits of non-retroactive stepper motor control is that in applications for the drive of machines, CNC milling machines or 3D printers, the positioning can be affected by an error that makes it…

New Arduino IoT development board unveiled: MKRFOX1200
This new IoT development board, which measures just 67 x 25mm in size, provides Makers with a low-cost solution for adding Sigfox connectivity to their DIY projects. The MKRFOX1200 takes the functionality of the Zero, throws in Sigfox’s global LPWA network, and shrinks it down into a smaller form factor. Sharing a similar footprint as its fellow…
Discovering Arduino capabilities in Analog/Digital Conversion (part1)
Let’s step into the word of analog-digital conversion for Arduino, by discovering how the dedicated pins work and how to use them for acquisitions. Part one. In the ADC of Arduino, an analog signal ranging from 0 to 5 V is translated in 10-bit code, which is 210 = 1024 combinations, with a…
Laser Anemometer
This instructable explains how to make an anemometer from an Arduino Uno R3, two VL6180X laser distance modules, and a section of plastic drain pipe or similar. Processing3 is used to display the wind speed and wind direction. The wind direction is independent of the pipe dimensions. The sensitivity to wind speed depends on the…
