A new cellular connectivity service for Arduino IoT Cloud

Arduino has launched a SIM-only service exclusively for IoT (internet of things) devices based on the Arduino platform to give developers and manufacturers cellular access to the Arduino IoT Cloud platform. The cellular service, provided by Arm Pelion Connectivity Management, means a single physical Arduino SIM can be used in more than 100 countries worldwide with one simple data plan. The Arduino SIM data ...

BLUE_P: Wireless Arduino Programming Shield

Many times we make projects using Arduino, while working with it we need to connect it with PC to upload program using USB cable. In this tutorial, I’m going to replace this USB cable with a wireless programming shield. This shield is build using a Bluetooth module HC-05. Program Arduino boards without using traditional USB cables. By using cheap Bluetooth module HC-05 you can Program the Arduino boards wir ...

Color sensor achieves high dynamic range with auto exposure

The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. The three common-cathode RGB photodiodes (U1) are reverse‑biased and pre-charged to VR (typically 0.5V) th ...

2018 Will Mark A Milestone in GPS Technology with 30-centimeter Accuracy

You’re in a crowded street with many high buildings around you and you find your car position on Google maps is wrong. That’s usual, right? This is caused from (fake/distorted) GPS signals reflected from the high buildings around you which make your GPS receiver do some wrong calculations. So be careful don’t always listen to what GPS assistant says! Even with no wrong calculations, the current GPS accuracy ...
