OH HAI! on Windows 10 IoT Core

Oh, Hai Hai ('hi') is an integration point for several stand alone smart home technologies.  Hai runs on the Raspberry Pi and can be adapted to optimize electricity consumption (lighting/HVAC) and water usage (irrigation/rain collection) in a number of ways. Hai was originally envisioned for any Pi running Raspbian OS, but is also being ported over to utilize the new Windows IoT Core on a Raspberry Pi 2. Th ...

Simple Infrared Barrier

Although infrared communication might look like the technology of the 1990s, it is still present in a multitude of applications around us. Every time you press the button of a remote control, it is most likely it is using the IR (infrared) technology for transmitting data. The TV remote is the most common example. Air conditioning remote controls are another good one. 1. Introduction Although a remote contr ...

Simple Infrared PWM on Arduino, Part 3 – Hex IR Signals

In Part 1 of this series, we demonstrated how to send signals using soft or Simple Infrared PWM on Arduino. In our Part 2 post we looked at sending RAW IR signals – specifically a RAW NEC signal and a longer RAW Mitsubishi Air Conditioner signal using soft PWM. We have since improved the PWM method shown in Part 1 Part 2 to provide better performance and improve portability. In this Part 3, we will take the ...

Controlling relay switches with an infrared remote

The infrared (IR) communication technology, which existed long before WiFi and Bluetooth, is still a key component in implementing major components of a typical home automation system. For example, IR technology is still used in cordless headphones, for intrusion detection in home security systems, and in handheld remotes for controlling home entertainment systems (TV, DVD, soundbox, etc), air-conditioning ...

Simple Infrared PWM on Arduino

We are often asked on discussion boards, about conflicts between IRremote or IRLib and other Arduino Libraries. In this post, we present a sketch for ‘Simple Infrared PWM on Arduino’. This is the first part in a 3 part series of posts. Part 1 shows how to generate the Simple Infrared PWM on Arduino (AKA carrier frequency), using any available IO pin and without conflicting with other libraries. Part 2 will ...

Converting infrared to RF signals with Arduino

In this project we will show you how to switch on and off the power sockets box with an IR remote. Not only the power sockets box, but other RF receivers can be switched on and off with the same IR remote as well. We used the RF remote switch library from Randy Simons http://randysimons.nl/ to control the RF part. This library supports different types of RF receivers. The receivers we are using besides the ...

How to Build an Infrared Distance Sensor Circuit

An infrared (IR) distance sensor is a sensor that can measure distance from a solid or physical object. An infrared distance sensor does this through light waves. It sends out infrared light and waits to receive it back at the receiver end. If it receives back the infrared light, this means that the light waves have bounced off of a physical object and has returned back to the sensor. If it does not receive ...

How to Build an Infrared Proximity Switch Circuit Using an Arduino

In this project, we will build an infrared proximity switch circuit using an arduino. This is a circuit in which a switch activates when the infrared sensor detects an object in its proximity. The infrared proximity switch sensor is a reflection-type photoelectric snesor which sends and receives infrared beams. Infrared proximity switches work by sending out beams of invisible infrared light. A photodetecto ...

Human Body Infrared Smoke Temperature Alarm System with Arduino

Web site: http://www.instructables.com/id/Human-Body-Infrared-Smoke-Temperature-Alarm-System/ Project Summary: The Human Body Infrared Smoke Temperature Alarm System works under the DC 5v voltage and uses the DH11 Temperature Module to detect the room temperature. When the module detects the temperature is higher than the maximum, the buzzer alarms and the red LED lights. When the MQ2 Smoke Sensor detects t ...

Bluetooth plus Infrared Controlled Robotic Arm

Hi. I’m Darren a 17 year old hobbyist, and this is the first Instructable I’m posting here, so I apologize if it kinda sucks! I hope it's good enough... So how did the idea of a robotic arm come to me? Well, the first thing I remember is our chemistry teacher (!) coming to me yelling that she has a project for me. It was for science Olympiad, however, apparently it was different from all the others, "someth ...
