4Duino Ultrasonic Sensor

In this project we will measure the distance of the nearby object using TS601-01 Ultrasonic sensor and 4Duino. An ultrasonic sensor has a transmitter (sends ultrasonic signals) and a receiver (receives the ultrasonic signal after it bounced off nearby object). The sensor estimates the distance of the object by transmitting a signal and determining how long the signal took to come back.  Ultrasonic Sensor ha ...

Obstacle Detection

In this project, we will use several ultrasonic sensors to create a robot car with obstacle detection feature. The sensors will help us estimate the distance of the car from the nearby obstacles. Thus allowing us to create routines that we can execute when the car is about to hit the obstacle while moving. If you want to know more on how an ultrasonic sensor work, please refer to 4Duino Ultrasonic Sensor pr ...

Using BMP180 for temperature, pressure and altitude measurements

The BMP180 is a new generation digital barometric pressure and temperature sensor from Bosch Sensortec. In this tutorial, we will briefly review this device and describe how to interface it with an Arduino Uno board for measuring the surrounding temperature and pressure. We will also discuss about retrieving the sensor altitude from its pressure readings. Experiment setup Bosch Sensortag’s BMP180 is an ultr ...

Beekeeping with Arduino

Beekeeping (or apiculture, from Latin: apis "bee") is the maintenance of honey bee colonies, commonly in hives, by humans. Things used in this project Story Beekeeping (or apiculture, from Latin: apis "bee") is the maintenance of honey bee colonies, commonly in hives, by humans. A beekeeper (or apiarist) keeps bees in order to collect their honey and other products that the hive produces (including beeswax, ...

Assistance for Visually Impaired featuring 4Duino-24

Blind Assistance is a project designed to help visually impaired people detecting obstacles in their way. It uses 4Duino, three ultrasonic sensors, one vibration motor and an LED. These components are attached to a walking stick. Blind Assistance alarms the user if there’s an obstacle in his way. These obstacles are detected using an Ultrasonic Sensor. It is able to measure distances from 2cm to 400cm. Ultr ...

WiFi Temperature Sensor featuring 4Duino-24

In this project we will quickly create a ‘temperature monitor’ that measures the ambient temperature of a room or an outdoor space. The temperature is measured by TMP35 temperature sensor and is displayed on the 4Duino screen. The data is also sent to Thingspeak IoT platform which enables data logging over a period of time. How it works Components 4Duino TMP 35 Temperature sensor Bread Board Jumper cables µ ...

Home Security featuring 4Duino-24

Home Security project is a password oriented security device. This uses 4Duino display as the user interface where the password can be entered. 4Duino is also used as the host device in this project. It handles a buzzer, an ultrasonic sensor, a uCAM-II and a magnetic switch. As a home security device, it sends an alarm to the owner when there is an attempted entrance or any malicious kind of entrance. Initi ...

MKR1000 Temp and Humidity Sensor

Send temperature and humidity data from an Arduino MKR1000 to Microsoft Azure. Things used in this project Story Paul DeCarlo has a great article on sending weather data from a Particle Photon to Microsoft Azure. I wanted to duplicate this with the new Arduino MKR1000. The Photon uses a webhook to send data from the Particle cloud to Azure. Since the MKR1000 supports HTTPS, data can be sent directly to Azur ...

Wireless Pulse Rate Monitor featuring 4Duino-24

The Wireless Pulse-Rate monitor is a conceptual project made for hospitals and clinics, its main function is to minimise the time that nurses or doctors need to visit each patient in a hospital. Usually, Doctors and nurses visit each patient to check vital signs, by using this project, they can monitor the patient’s vital signs even without visiting them, and this also allows them to remotely monitor the pa ...
