GND, SCK, CS and SO pins present on the same side. The VCC will be connected with the 5V pin from the Arduino. GND of both the devices will be in common. The default SPI GPIO pins of Arduino are being used to connect with each of the remaining SPI terminals of the MAX6675 module....
we need to build a sensor node to read the energy consumption of the house and publish that consumption to the MQTT broker. There's a couple ways to do this. I'm using an Arduino Yun. It's the least complicated method, but not the least expensive. If you want, you can use an Ard...
Enhance your Arduino projects with the GY-219 Current Power Supply Sensor Breakout Board. This hall effect DC current sensor offers I2C interface and high-side DC current measurement for precise data readings.
This paper presents a novel mobility AT device providing user orientation in outdoor environments. The device consists of a smartphone and a wearable tactile display. The first encompasses a GPS sensor that ensures a reasonably accurate user location, tracking, and guidance in space. The latter con...
The proposed mailbox uses a passive infrared (PIR) motion sensor, cameras, solenoid locks, and RFID reader controlled by an Arduino microcontroller with Wi-Fi connectivity. For security, the proposed mailbox captures an image whenever a nearby motion is detected, and opens the mailbox lock when...
work in [10] is focused on digitizing building addresses and storing them in Radio-frequency identification (RFID) tag, which can be used for drone delivery. The proposed mailbox uses a passive infrared (PIR) motion sensor, cameras, solenoid locks, and RFID reader controlled by an Arduino mic...
