Arduino ed

I'm having the cheap clone from Maker Factory, with an atmega328p. Trying to work on Manjaro linux.

Setup ed

• open the board manager (menu tools/boards)
• install "Arduino AVR boards"
• select the "Arduino Uno"
• programmer: "ArduinoISP"
• port: "/dev/ttyACM0"

Serial monitor ed

Had Java errors first, because my system used an outdated version of java.

sudo archlinux-java set java-10-openjdk
