// Define RX (JDY-40 TX) and TX (JDY-40 RX) pins SoftwareSerial jdy40(2, 3); // RX = pin 2, TX = pin 3
Send temperature every 60 seconds, then sleep the Arduino + JDY-40. jdy40 arduino example best
This sketch sets up a "Pass-through" bridge. It checks for incoming configuration commands from the PC and relays all other data transparently. // Define RX (JDY-40 TX) and TX (JDY-40
. It is highly valued for its simplicity, as it uses a standard UART interface that can be controlled with basic serial commands on an Arduino MSS Eletrônica 1. Hardware Setup & Pinout operates on iFuture Technology . Connecting it to a 5V source may damage the module : 2.2V to 3.6V MSS Eletrônica : System ground. : Connect to the Arduino's RX/TX pins (cross-connected) iFuture Technology Connecting it to a 5V source may damage the module : 2
