Spining BLDC motors at super Slow speeds with Arduino and L6234


I used specialized triple half bridge IC L6234 (~ 8$). You can make the same spending less money (but more time) with MOSFET transistors or other IC.

L6234 datasheet is surprisingly useless. Go straight to Application Note AN1088 instead.

I added current limiting resistors (1kΩ) to all INputs and ENable pins, a bunch of capacitors recommended in application note and current sensing shunt resistor 0.6Ω (big blue one).
