This cost-effective 433MHz wireless relay switch circuit allows remote relay control using an RF transmitter and receiver module. It is ideal for scenarios where wired connections are impractical or ...

The development was done on an Arduino Due. Tests have shown that the working range of several 433Mhz receiver modules strongly depend on the quality of the power supply. When the Arduino Due is ...

Remote control based on cheap keyfob modules. Use the buttons as bits to encode up to 15 individual channels. Costs: €5! I was playing around with some 433MHz wireless modules which are sold all ...

A fully secure receiver and transmitter pair works on radio frequency, Control the things wirelessly without internet, Wifi and bluetooth. Get all the required files ...

Making our projects Wireless always makes it to look cool and also extends the range in which it can be controlled. Starting from using a normal IR LED for short distance wireless control till an ...

We frequently get home automation tips, many of which have simple circuit-based on/off control for lights. [Paulo Borges] has created something quite different, however, with his in-the-wall ...
