Automatic Gate Slider Under $100

“Over the summer, my dad motivated me to look into buying a gate automation system and setting it up. So I started my research and looked into package solutions on AliExpress and local vendors. The local vendors were offering complete …

New Wireless IOT Sensor Layer for Home Environmental Monitoring System

“This Instructable describes a lower-cost, battery-powered wireless IOT sensor layer for my earlier Instructable: LoRa IOT Home Environmental Monitoring System. If you haven’t already viewed this earlier Instructable, I recommend reading the introduction for an overview of the capabilities …

BridgeDuino: A Wireless Arduino HUB and Shield

“BridgeDuino (R 0.11) is a Swiss army knife PCB for rapid networking of inexpensive wireless communication modules. Breadboards are super for one-off experiments. But after prototyping half a dozen wireless prototypes involving more than just two Arduinos, the wiring …

Repurposing an LED RF Remote to Control “anything”!

“In this project I will show you how to repurpose an LED RF remote in order to control pretty much anything you want with it. That means we will have a closer look at the transmission process of the RF …

RF433Analyser

“This instructable creates a measurement instrument to help analyse RF 433MHz transmissions which are commonly used for low power remote communications in home automation and sensors. It could probably be easily modified to work 315MHz transmissions used in some countries …

ILumos Remote Control

“The iLumos range of smart light switch and dimmers work very nicely. They install easily into UK as they don’t require a neutral connection which is often not present in UK lighting switch points. They use 433MHz transmissions from …

Varmint Detector

“Using Eagle, the PCB I designed is a Varmint Detector. Varmint: noun, North American informal - a troublesome wild animal. In my case, crows and chipmunks attacking our garden. They really arent much of a problem, this is just my excuse …

ATtiny Radio Controller

“We have seen a lot of radio controllers on this channel till now. We’ve seen one using the NRF24 module and making the entire board, weeks back we had the controller made with the HC 12 radio module and …

Using The 433MHZ RF Transmitter And Receiver With Arduino

“While building microcontroller based projects, there are occasions where communication will be required between two devices, either in a duplex/transceiver based operation (where both devices can transmit and receive at the same time) or in a simplex-based operation where …

Autostat : a Remote Thermostat

“The question you are probably asking is “why are you making another remote thermostat?” The answer to that question is, I had to, and the market smart thermostats are too expensive. Fair warning, this is “proof-of-concept” build that would require …
