Marlin 2.0 Firmware configured for Ender 3 + BL Touch

This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. The standard configuration file from Marlin distribution was carefully reviewed to include the latest Ender 3 specific settings from the official Creality firmware and from Antclabs.

Control Arduino via USB OTG from Android

This script allows Johnny-Five to run from a Termux terminal communicating with other Android apps or external devices by using the TCP protocol without root, without bluetooth and without the WiFi shield. The reason for the TCP protocol is that Termux still does not implement USB-OTG to Serial drivers and the vanilla Johnny-Five would hang right out the box because of this limitation.
