The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

Eight LEDs with 74HC595 - This project shows how to control eight LEDs using a 74HC595 shift register with Arduino UNO R3. IR Receiver Module - This project uses an IR receiver module to receive and ...

The relay module will need 5V from Arduino to power up and will get input from four different ... int R1 = 6; // Relay 1 int R2 = 7; // Relay 2 int R3 = 8; // Relay 3 int R4 = 9; // Relay 4 // ...

Shown below is the basic hardware setup diagram. Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems ...

See the txt files in the info folder for brief captures of the interactions. Note that once the BW16 module is downloaded with an arduino sketch those interfaces are no longer available unless you ...

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 ...

Arduino introduces its new module »Uno R4«. It is the successor of the R3 module and contains a Wi-Fi module in the extended version. It is also the first Arduino module with 32-bit microcontroller.

The Easy Module Shield is compatible with the Arduino Uno R3 only. Dragino’s LoRa Shield is an excellent board that adds a long-range transceiver to the Arduino, with the trade-off being low data ...

Instead, he drew up a simple schematic that used an Arduino Nano, an FM radio module based on the TEA5767, and an audio amplifier based on the LM386. A single button on the Arduino helps cycle ...
