Watch the demonstration video below to learn more about Zola’s project which uses TX and RX transducers desoldered from an HC-SR04 module, together with a pair of Arduino Uno development boards ...

⇒ Arduino-Compatible Interface (UART): Easily connects with Arduino and other microcontrollers via serial communication (TX/RX pins). ⇒ Multiple Protocol Support: Supports TCP/IP, HTTP, FTP, and MQTT ...

This cable connects the Arduino to the ESP8266 WiFi module. The TX and RX lines are then tapped into. Each wire is routed to the RX pin of two different serial to USB adapters.

Arduino GPS Tracker Circuit Diagram The Arduino GPS tracker circuit connects three main components: Arduino UNO R3, NEO-6M GPS module, and SIM800L GSM module. This design uses both hardware and ...

Here's an interesting way to control an Arduino using data-over-sound, demonstrated by Chirp. They show how to use their SDK to send an RGB value to change the colour of a on-board LED.
