DIY Arduino PIR Motion Sensor Lighting & Security From the minds at We wanted to save energy, and create convenience, by adding motion sensors to our lighting circuits. Maybe you want some notification of an intruder. Both can be done with a PIR Motion sensor. Vector Scratch Blocks In September 2014 Computing will be a new curriculum subject and I wanted to make some resources that could be used to support Scratch After seeing these hands-on blocks I thought it would be great if anyone could make their own. So I set about creating some vector versions of the standard Scratch blocks that could be scaled to any size required.
200+ Arduino Projects List For Final Year Students Arduino is a single-board microcontroller. It is intended to make the application of interactive objects or environments more accessible. The hardware consists of an open-source hardware board designed around an 8-bit Atmel AVR microcontroller, or a 32-bit Atmel ARM. Electronics : Microprocessors : Arduino Uno output to VGA monitor This post shows how you can output VGA signals to a monitor, turning your Uno (or similar) processor into a "video card". Example: The only extra hardware used here was 5 resistors, and a DB15 socket to plug the monitor cable into: Watch live demo: VGA Timing
Creative Computing 7 units44 activitiesremixing encouraged download the guide> help learnerscreate new worldswith computing download the guide an introductorycomputing curriculumusing Scratch Arduino and Python For a project (check out my blog for updates) I'm working on I needed to be able to communicate with my arduino, luckily the arduino can communicate though serial. It turns out almost any programming language can be used for serial communication but python seems to be the easiest so far. I had some problems getting it all to work and finding a basic tutorial online proved very difficult. So hopefully this guide will explain the basics to anyone that is looking to start using the serial functions that the arduino provides. I'm going to assume that if you're reading this you have some knowledge of how an arduino works and how to upload sketches and what not, however I will explain the arduino code when we get there. The python code is very basic but I will do my best to explain it as well.
DevDuino Sensor Node V1.2 (ATmega 328) Introduction devDuino Sensor Node V1.2 (ATmega 328) is a compact Arduino-compatible microcontroller and is designed to build wireless networks based on transceiver nRF24L01+. You can easily connect other sensors (series Grove) or actuators to this platform, to build your remote monitoring or controlling system.. Model: 830068001 Feature Built on Arduino-compatible architecture Clock frequency - 16MHz (may be reduced in order to reduce energy consumption by up to 8MHz) Built-in temperature sensor MCP9700 (-40 ° C +125 ° C, accuracy of ± 2 ° C) Built-in voltage divider (to monitor the supply voltage) Built-in button Built-in LED 2 power circuits 2.4G nRF24L01 + (by jumper) 3 GROVE-compatible connector: I2C, Analog, Digital Powered by one element CR2032 (not included) Dimensions 30 x 40 mm
ScratchX What is ScratchX? ScratchX is a platform that enables people to test experimental functionality built by developers for the visual programming language Scratch. What's the difference between Scratch and ScratchX? MySensors - Touch Display Scene Controller Sometimes you might want to control more advanced scenarios in your home automation project. This is when a scene controller comes in handy. In this example we've used a touch screen to display the scene launch options. The buttons can be customized in the sketch code to your preference.
