As we have learnt in previous tutorials that the XBee module can act as a Coordinator, Router or an End device but it need to be configured to work in desired mode. So before using the XBee modules ...

The circuit diagram of the smart timer for liquid mosquito repellents is shown in Fig. 2. It is built around the Arduino Uno board (MOD1), RTC DS1307 module (MOD2), 5V relay module, 5V buzzer (B1), ...

1. The module has an external antenna and built-in EEPROM with TTL interface. Its default baud rate is 9600bps, and it works in standard NMEA format. The circuit diagram of the GPS-based timer is ...

[Scott-28] recently sent in a particularly well-documented project that turned an antique rotary phone into a digital kitchen timer using an internal Arduino. While we’re not sure practical is a ...
