The transmitter is paired with an encoder that is provided a binary code by wiring pins to power and ground. The receiver's decoder listens for that code and, when the codes match, changes the state of one of its pins, which shorts the garage door's remote terminals to signal it to open. The result is a single-button handheld remote that looks a bit like something from 1950s science-fiction but is an effective solution. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do RF transmitter and receiver modules communicate using encoder and decoder chips? An encoder chip wires several pins to power or ground to set a fixed binary code, which the RF transmitter sends out. A matching decoder chip on the receiver listens for that exact code, and when it matches, flips the state of one of its output pins. That pin change can then be used to short two terminals together, such as a garage door opener's remote input, triggering the action. _Builders replacing a dead garage remote can find similar RF module walkthroughs on daily.dev._ ## Similar posts on daily.dev - [Someone built a $10 ESP32 smart garage door opener that works with Home Assistant](https://daily.dev/posts/someone-built-a-10-esp32-smart-garage-door-opener-that-works-with-home-assistant-ohikudqvi) · XDA Developers · 2 upvotes · 0 comments - [A Thoroughly Modern Minimalist Transceiver](https://daily.dev/posts/a-thoroughly-modern-minimalist-transceiver-1xvvauydq) · Hackaday · 0 upvotes · 0 comments - [Convert old IR remote controls into presentation clickers using an RP2040 USB board and open-source TTVKTR firmware](https://daily.dev/posts/convert-old-ir-remote-controls-into-presentation-clickers-using-an-rp2040-usb-board-and-open-source--gdyplywaf) · CNX Software · 0 upvotes · 0 comments - [A Beginner’s Two-Component Crystal-Style Wi-Fi Detector](https://daily.dev/posts/a-beginner-s-two-component-crystal-style-wi-fi-detector-fqng9ppg1) · Hacker News · 1 upvotes · 0 comments - [An IR Blaster Project, In A Nutshell](https://daily.dev/posts/an-ir-blaster-project-in-a-nutshell-w94jzvhcs) · Hackaday · 0 upvotes · 0 comments --- [View this post on daily.dev](https://daily.dev/posts/simple-reliable-rf-remote-control-wx0vwhgpx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Simple, Reliable RF Remote Control","url":"https://daily.dev/posts/simple-reliable-rf-remote-control-wx0vwhgpx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/simple-reliable-rf-remote-control-wx0vwhgpx"},"datePublished":"2026-10-25T14:26:17.047Z","dateModified":"2026-10-25T14:26:40.967Z","description":"A broken garage door remote led Igor Brichkov to demonstrate a project using RF transmitter and receiver circuits.
