Very simple 433MHz (EU/ASIA) 315 MHz (US) RF jammer for keyless cars theft prevention

this is example of cloning my garage keys with Arduino Digispark and FS1000A transmitter. The keys sequences were recorded first using Universal Radio Hacker tool

This is a simple 2 WAY radio chat device built from Digispark (ATTINY85) + FS1000A + MX-PM-5V modules. Allows "IRC" like radio communication between several PC connected to 433MHz/315MHz frequency.

Arduino/FreeRTOS library to operate 433/315Mhz transmitters and receivers

toggle intertechno switches via mqtt or web page

Generate RF distrotion using esp8266 chip and FS1000A module.

Implementation of FreeRTOS with IOT, using Arduino + transmitter and Nodemcu + Receiver with Wifi connection to publish MQTT message

Temperature control system using ESP32 and DS18B20 temperature sensors, controlling Nexa power plugs over RF433 and logging/synchronization with Google spreadsheet
