Home » content Arduino Projects: Graffiti, Greenhouses, and More Submitted by Roy Schestowitz on Friday 10th of June 2022 12:06:42 AM Filed under Hardware Graffiti robot paints like a human | Arduino Blog Robots are capable of far more precise and accurate motion than humans are. That is great when you want a robot to assemble a PCB or perform heart surgery. But it’s a problem when you want robots do something creative — they’re just too perfect. The lack of human-introduced flaws makes robot artwork feel soulless. To overcome that, Georgia Tech graduate students built a graffiti robot called GTGraffiti that paints with the fluidity of a human. GTGraffiti is a cable-driven robot can cover huge canvasses and even entire walls. Four winch mechanisms connect to the four corners of the robot via cable wires. By increasing or decreasing the length of each cable, the robot can position itself at any XY coordinate on the work surface. The robot end effector that hangs from the cables carries a can of spray paint, which it can actuate on demand. ODrive 56V motors turn the winches and a Teensy development board controls those through ODrive drivers. The spray can actuator utilizes a hobby servo motor controlled by an Arduino Nano board, which receives power from a 10,000mAh USB batter pack. Automated window system helps keep the greenhouse climate regulated | Arduino Blog Greenhouses are excellent ways to grow plants due to their compact nature and the fact that they can absorb and store the sun’s light as heat to keep their internal temperature higher than outside. But when it comes to adding ventilation for cooling things down, decreasing the humidity, or simply to avoid rain, most non-commercial ones still rely on someone to manually open or close the windows. This need for automation is what drove Michael Bernhard to create his own greenhouse climate regulation system. This project relies on a Nano Every to read the ambient temperature/humidity as well as control up to six motorized windows via three L298N dual H-bridge drivers. The Nano receives commands and other data over WiFi from an accompanying ESP8266 board for wireless remote control with a mobile phone. Each of these components and their connectors were added to a custom PCB and placed within a simple wooden enclosure to keep moisture out. An LCD at the top shows pertinent information such as the time, temperature, and humidity. Current Sensor (ACS712) with Arduino UNO: Using the Hall Effect To measure the current passing through the wire, ACS712 is the best current sensor to deal with, as it can measure up to 5A In this tutorial, we’ll interface the current sensor (ACS712) with Arduino Uno, dealing with current sensing and utilization for current control. This tutorial provides the coding, wiring diagram and component list. » Login or register to post comments Printer-friendly version 32 reads PDF version More in Tux Machines HighlightsFront PageLatest HeadlinesArchiveRecent comments All-Time Popular StoriesHot TopicsNew Members We're Eighteen Today TODAY is a special day because tuxmachines.org was registered exactly 18 years ago.

Some examples are Kali for security testing, DragonOS for software-defined radio, or Hannah Montana Linux for certain music fans. Anyone can roll their own Linux distribution with the right tools, including [Shadly], who recently created one which only loads enough software to launch the 1993 classic DOOM. The distribution is as simple as possible and loads no bloat other than what’s needed to launch the game. It loads the Linux kernel and the standard utilities via BusyBox, then runs fbDOOM, which is a port of the game specifically designed to run on the Linux framebuffer with minimal dependencies. After most of that, the only thing left is to use GRUB to boot the distribution, and in just a moment, Doomguy can start slaying demons. The entire distribution is placed into a bootable ISO file that can be placed on any bootable drive. PeerTube 4.2 Comes with In-Place Video Editing Capabilities PeerTube 4.2, a free video platform, includes detailed viewer stats for videos, video editing directly from the web interface, and much more. PeerTube allows anyone to set up their video streaming site. It is a free, self-hosted, and open-source software that can be installed on your server to create a video hosting and sharing platform. In other words, it is like having your personal YouTube at home. Furthermore, all PeerTube sites can connect to each other, and users having accounts on one can interact with people on the others. All PeerTube servers are interoperable as a federated network, and video load is lowered thanks to P2P (BitTorrent) in the web browser via WebTorrent. Recently, PeerTube’s developers have finally launched PeerTube 4.2. Let’s have a look at the new features. Games: 3300 Games for Steam Deck and Tuxedo Stellaris Gen 4 3300 Games Now On The Steam Deck with Resident Evil (1) and Dead or Alive 6 as Verified - Boiling Steam We are still observing a relatively low rate of addition of verified/playable games for the Steam Deck. Nevertheless we are now more than 3300 games validated (3312 games to be precise at the time of publication) on the Steam Deck – in two categories... Tuxedo Stellaris Gen 4: Hardware Beyond Belief - Boiling Steam After many months of patiently waiting for the next-generation Tuxedo Stellaris Gen 4 laptop by Tuxedo Computers, I’m happy to finally report it’s now in my hands. I had reviewed the third generation last September. Notable improvements with this version is the upgrade in the CPU and RAM department, utilizing Alder Lake graphics and DDR5 respectively. It also comes with a more performant GPU, sporting a RTX 3080 Ti. This laptop is even meaner than it was before.

Comment piloter un moteur triphasé avec un microcontrôleur miniature ? 🚀 Dans ce tutoriel complet, je réponds à la commande d'une entreprise pour programmer un PIC 12F675 afin de gérer l'inversion de sens d'un moteur avec des cycles précis.
Nous allons voir ensemble tout le processus de création : de la rédaction du code sur MikroC à la simulation sur Proteus, jusqu'au test réel sur plaque d'essai (breadboard). Vous découvrirez comment gérer les temps de fonctionnement (30s) et les pauses de sécurité (10s) pour éviter d'endommager le moteur à cause de l'énergie cinétique.
Ce que vous allez apprendre : - Configuration et programmation d'un PIC 12F675 via un programmateur. - Utilisation d'un régulateur 7805 pour protéger votre microcontrôleur (Logique TTL 5V). - Importance des condensateurs de filtrage et de déparasitage (104). - Lecture d'un chronogramme et simulation logicielle avant passage au réel. - Câblage étape par étape sur plaque d'essai.
