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 ...

AmpStrike – Battery Powered Bench Power Supply

Introduction This is a small bench power supply that is powered by two lithium-ion batteries. The project was inspired by Dave Jones from EEVblog but the design is completely mine. The voltage range is 0-20V regulated in 10mV steps and maximum current is 1A with current limit set in 1mA steps. Schematic Linear Voltage Regulator The power supply runs on a linear voltage regulator built on discrete components ...

Stock Monitoring featuring 4Duino-24

In this project, we will use several IR sensors to check if an item from an inventory box is present or not. This project makes use of a 4Duino-24 to check whether an item is present or missing from the inventory. The 4Duino uses its analog pins to read the values from each IR sensor. This reading value changes depending on whether or not the item is present. The 4Duino is set to send most recent status to ...

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 ...

‘Circuit Cobbling’ the Riffle Data Logger

I always considered circuit boards like this something you bought, not something you made. Not any more. I actually helped to make the board in the picture above. And it was awesome fun. The board is designed to monitor the conductivity (and, possibly, contamination) of water in lakes and streams, with the wonderful feature that it fits through the mouth of a regular water bottle. It’s called Riffle and it ...

Arduino based Vehicle Tracker using GPS and GSM

In our previous article, we have learned about “How to interface GPS module with Computer and How to make a GPS updated Clock”. In this project we are going one step ahead with GPS and going to track a vehicle using GPS and GSM. This Vehicle Tracking System can also be used for Accident Detection Alert System, Soldier Tracking System and many more, by just making few changes in hardware and software. Tracki ...

Get ready for MPLAB Express

I credit the maker movement with bringing electronics back from the crusty old and lonely electronics hobby back into the main stream. The Arduino is the micro of choice for this army of makers and I conceded it made sense… you install the IDE, plugged in your board into the USB port and a couple clicks later and you have an LED blinking.. the most exciting blinking LED you’d ever seen in most cases. I stuc ...

Monolithic linear battery charger operates from inputs up to 60V

Introduction For charging relatively low capacity batteries, or maintenance charging backup and keep-alive batteries, linear topology battery chargers are valued for their compact footprints, simplicity and affordability. Even so, there is a dearth of linear chargers that accept a 10V or higher input voltage, leaving many industrial and automotive systems underserved. Some switch mode solutions can accept h ...
