Arduino: AnalogWrite() control by Serial communication (Usart) - set LED brightness throw Serial monitor in Arduino Ide
// Control the LED brightness by sending value throw Serial monitor in Arduino Ide
// AnalogWrite() reference: https://www.arduino.cc/en/Reference/AnalogWrite
// Select the ride pin which support PWM mode for analogWrite()
// Pinout Arduino Nano: https://goo.gl/Dffq8f (the pins with oscillation symbol - PWM pin in legend)
int LED_PIN = 11;
// Next step - use Serial.parseInt() for control brightness
// ParseInt() reference: https://www.arduino.cc/en/Serial/ParseInt

JarekParal / KiCAD_gerbers_rename_for_Gatema_Pool_servis.py
Last active March 13, 2017 00:41 — forked from xesscorp/rename_gerbers.py
Python script for renaming KiCad Gerber files for manufactory Gatema and their Pool servis (prototype PCB)
# Original source: https://gist.github.com/xesscorp/8a2ed1b8923f04ae6366
# Edit by Jarek Paral <[email protected]>
#
# KiCad outputs Gerber files with extensions that aren't recognized by the most commonly used
# PCB manufacturers. This Python script renames the files to what want manufactory Gatema for
# (company in Czech Republic which produce PCB - http://www.gatema.cz) Pool servis - prototype PCB
# (http://pcb.gatema.cz/kriteria-dat-pro-pool-servis/).
# Just execute this script in your KiCad project directory and the Gerber files will be renamed.
