Interfacing VL6180 ToF Range Finder Sensor with Arduino for Distance Measurement

VL6180 differs from other distance sensors as it uses a precise clock to measure the time taken by the light to reflect back from any surface. This gives VL6180 a benefit over other sensors because it’s more accurate and immune to noise.

Arduino HM-10 BLE Module Tutorial

Arduino HM-10 BLE Module Tutorial

The HM10 has become a very popular Bluetooth 4.0 BLE module. The HM10 is a Bluetooth 4.0 based module only, so it will not connect with Bluetooth 2/2.1 module such as HC-05, HC-06 and other Bluetooth modules. The HM10 is controlled via AT commands sent over the serial UART connection. HM-10 is a Bluetooth Low Energy (BLE) module, to know more about this module, check out the HM-10 BLE datasheet

MQTT Based Raspberry Pi Home Automation: Controlling Raspberry Pi GPIO using MQTT Cloud

In previous tutorial we have discussed about MQTT Protocol and installed local MQTT server on our Raspberry Pi for controlling the GPIO locally. But the drawback of local MQTT server is that we cannot control the GPIOs from anywhere in the world, it only provides services locally. But if this MQTT server is hosted on some cloud then any appliances connected to Raspberry Pi can be controlled globally.

DIY Arduino Based Color Sorter Machine using TCS3200 Color Sensor
Here in this tutorial we will make a color sorting machine using a color sensor TCS3200, some servo motors and Arduino board. This tutorial will include the sorting of colored balls and keeping them in the relevant color box. The box will be in the fixed position and the servo motor will be used to move the sorter hand to keep the ball in the relevant box.

Charge Pump Circuit – Getting Higher Voltage from Low Voltage Source
Boost converters are inefficient at low powers, since a lot of energy is consumed just for keeping the regulation on point and driving the power switch. Also, switch mode converters of this type are noisy – this is a problem if you’re dealing with sensitive circuitry. You’re in the uncomfortable position of an over-engineered solution. Linear regulators don’t work in reverse, so that’s ruled out as under-engineered.

Simple Wireless Power Transmission Circuit to Glow an LED
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.

Simple Curve Tracer Circuit: Tracing the Curve for Resistor, Diode and Transistor

Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s straight VI line or a transistor’s collector voltage versus current curve.

These curves give us an intuitive understanding of how a device behaves in a circuit. An analytical approach might involve plugging in discrete voltage and current values into a mathematical formula and graphing the results, commonly with the x axis representing voltage and the y axis representing current.

Different Types of Transformers and Their Applications
A transformer is a widely used device in the electrical and electronics domain. It is an electromagnetic device which follows the basic principle of electromagnetism discovered by Michael Faraday. We have covered about Transformers construction and operation in detail in previous tutorial. Here we will cover different types of transformers used in different types of applications. However, all types of transformers follow the same principles but they have different construction method.
