Things used in this project

Hardware components

STMicroelectronics STM32F030K6T6
a very cheap ARM Cortex-M0 mcu. 48Mhz, 32KB flash and 4KB ram. plus many feature rich peripherals. that's not a lot, but just enough to beat atmega328 by higher features and a fraction of the price.
×1
CH340G
the infamous USB to Serial Converter needs no introduction
×1
Texas Instruments ULN2003
an old, but trusty 7 channel darlington array.
×1
Texas Instruments LP2951
a real low dropout linear regulator.

Labcenter electronics, Proteus

Hand tools and fabrication machines

Soldering iron (generic)
Soldering iron (generic)
just a simple iron with an spoon type (C series) tip; best choice for drag soldering.
Solder grease
the perfect soldering flux. a very thin layer on a pad is enough to make soldering fun.
