Want to add Bluetooth Low Energy functionality to your Arduino-based project? in this tutorial, Martyn Currey shows you how to take advantage of the advanced features of our RN4870/1 BLE module. The RN4870/1 is a small (only 12mm wide) BLE module from Microchip. What makes this a little bit special are the advanced features that allow you to create your own services and characteristics.


Miniature Volt Meter cum Battery Voltage Monitor


Fayaz Hassan

Most of the times, measurement in electronic circuits, our requirement is measuring DC voltage.  Normally, we will set the multi-meter to DC voltage mode and check the voltage levels at various points on the PCB.  Mostly, our requirement lies between 5V to 15V DC.  The circuit shown is simple, occupies less space and can directly connect to the DC voltage for measurement.  To minimize the size and power consumption, 8 pin MCU and 0.96” OLED is used in the circuit.

Andy Rubin, Nick Sears, Rich Miner, and Chris White founded Android Inc. in October 2003. Firstly, Andy Rubin developed Android OS for digital cameras but he realized that the market for digital camera operating systems perhaps was not all that big. In 2005, Android wasbought by Google and Andy Rubin along with other co-founders continued working under new owners. In 29 June 2007,iPhone was released by Apple Inc with iOS, which was the first OS in the mobile market.

Healthcare sector is gradually achieving digital integration at all steps of a patient’s journey from lookout for symptomatic information, diagnosis, treatment and follow ups. Automation has embedded itself within various health care operations. The past two decades have seen the successful launch of various eInitiatives that’ve revolutionised most aspects of life, and their effectsare now being felt in the sphere of healthcare too.

Just like artificial intelligence, drones, and IoT, facial recognition technology is also defining our millenium. Initially it was only used among military services and It is finally making its way into the mainstream world. Now even the most commonly used devices like our smartphones are making use of facial recognition while cameras are using it for identifying faces that need to be captured for photo. Now, we also have those cameras that recognize faces of pets like dogs and cats.

Looking around, we find ourselves to be surrounded by various types of embedded systems. Be it a digital camera or a mobile phone or a washing machine, all of them has some kind of processor functioning inside it. Associated with each processor is the embedded software. If hardware forms the body of an embedded system, embedded processor acts as the brain, and embedded software forms its soul. It is the embedded software which primarily governs the functioning of embedded systems.

Circuit Design: Pulse Amplitude Modulation


There are different kinds of modulation technique based on varying the properties of a pulse train. The Pulse Width Modulation (PWM) varies the width of individual pulses according to the amplitude of the modulating signal. The Pulse Position Modulation (PPM) varies the position of individual pulses from their mean position according to the amplitude of the modulating signal. The PWM is a kind of modulation technique indented for power efficiency, but the power required to transmit individual pulses varies significantly.

TCP/IP Based IoT Communication with ThingSpeak Platform : IOT Part 29



ESP8266 based TCP-IP Connected ThingSpeak Arduino Temperature Monitor Circuit In the previous tutorial, features, advantages and limitations of TCP/IP Protocol were discussed. Though, TCP/IP is not best suited for IoT applications due to packet overheads, still being the most common protocol stack on internet, it offer ubiquitous connectivity. An IoT device can be made to communicate with a cloud or server using TCP/IP protocol without any hassle of network programming and network administration. In this project, an IoT device will be designed that could transmit sensor data to ThingSpeak Platform using the TCP/IP protocol.
