I am working on a semi-auto detection idea for Arduino for the Scope project.
It does require a little user intervention but minimal.
It works by just responding to two on screen prompts to unplug and plug Arduino
into a USB port.
There are two versions and both work perfectly well and give... (3 Replies)
In my further exploration of Arduino, today I decided to install the arduino-cli on my mac today.

HI all...
(Apologies for any typos.)
To add to Neo's Arduino subject matter I have decided to upload this in ".zip" format.
Ignore "*.info" files these are AMIGA icons only and also the "HAM" drawer as these are photos in ancient AMIGA HAM modes.

Waiting for more fun Ardunio parts from AliExpress, I decided to test two cheap Chinese Arduino UNO clones.
The Arduino UNO R3 (CH340G) MEGA328P
The Wavgat UNO R3 (CH340G) MEGA328P
Both of these Chinese Ardunio clones sell for about $3 USD, delivered to your door.
The bottom line is... (0 Replies)
Just finished a quick Python script to send the current unix time over to the Arduino from macOS, so in the absence of GPS or some other way to get the unix timestamp (epoch time) to the Arduino, I can get my macOS and Arduino UNO synced to within a second.
Normally, when the Arduino starts... (9 Replies)
Here is a sketch to do basic testing for the Arduino UNO and the MLT-BT04.
This BLE module works with IOS (iPhone) and I'll add some details on my IOS testing with an iPhone in a follow-up post.
For now, here is the basic BLE (HM-10) sketch for the Arduino UNO:

ACPI_VIDEO(4) BSD Kernel Interfaces Manual ACPI_VIDEO(4)NAME
acpi_video -- ACPI Video Extensions driver
SYNOPSIS
device acpi_video
DESCRIPTION
This driver uses the ACPI Video Extensions to control display switching and backlight brightness. The availability of the sysctl(8) vari-
ables depends on the functions offered by the host's ACPI implementation.
SYSCTL VARIABLES
The following sysctls are currently implemented, where <device> is crt, lcd, or tv:
hw.acpi.video.<device>.active
Current state of the output device.
hw.acpi.video.<device>.levels
List of supported brightness levels.
hw.acpi.video.<device>.brightness
Current brightness level of the device.
hw.acpi.video.<device>.fullpower
Preset brightness level to be used in full power mode.
hw.acpi.video.<device>.economy
Preset brightness level to be used in economy mode.
Defaults for these variables can be set in sysctl.conf(5), which is parsed at boot-time.
SEE ALSO acpi(4), loader.conf(5), sysctl.conf(5), sysctl(8)HISTORY
The acpi_video driver first appeared in FreeBSD 5.3.
AUTHORS
The acpi_video driver was written by Taku YAMAMOTO <taku@cent.saitama-u.ac.jp>. This manual page was written by Mark Santcroos
<marks@ripe.net>.
BUGS
Some systems only perform output switching via SMM even though they export the proper information via ACPI. On such systems, the proper
hotkeys or OEM driver (for example, acpi_toshiba(4)) must be used instead.
