ULTRA SMALL DC-DC CONVERTER WITH INTEGRATED INDUCTOR

Leave a Comment / Electronics News Updates / Ibrar Ayyub

The XCL206 series is a synchronous step-down micro DC/DC converter which integrates an inductor and a control IC in one tiny package (2.5mm×2.0mm, H=1.0mm). A stable power supply with an output current of 600mA is configured using only two capacitors connected externally. Operating voltage range is from 2.0V to 6.0V(XCL20xG:1.8V-6.0V). Output voltage is internally set in a

How to Use ADC (Analog to Digital Converter) in AVR – Atmega32

Leave a Comment / Electronics News Updates / Ibrar Ayyub

Using LM35 Sensor and Atmega32 ADC to measure Temperature Analog to digital conversion is generally needed whenever we deal with a sensor that produces an analog output (for example: LM35 temperature sensor), which is the case for a wide range of sensors. When dealing with such sensors we have to convert the analog signal coming

Analogue to Digital Conversion on an ATmega168

Leave a Comment / Android Projects, AVR ATmega Tutorial, Microcontroller Programmer Projects / Ibrar Ayyub

Many AVR microcontrollers are capable of doing Analogue to Digital Conversion. The ATmega168 has 6 ports (8 ports on the SMD packages) that can be used for analogue input. This tutorial shows you how. The circuit The Breadboard layout is based on the Atmega8 breadboard circuit which is described in Atmega8 breadboard circuit Part 1

Capacitor self-diagnostics

Leave a Comment / Electronics News Updates / Ibrar Ayyub

The electrolytic capacitor is far from being the most reliable electronic component. One of its failure modes – a gradual loss of capacity – can hardly be noticed until power supply malfunction occurs. Thus, any chance to monitor the condition of the filter capacitors of an electronic device in situ would be a useful thing.

Curious C-Beeper

Leave a Comment / Electronics News Updates / Ibrar Ayyub

Curious C-Beeper is a fun to build little probe that can be used to quickly detect the capacity of capacitors in pF nF range, test their stability with temperature changes, find broken wires, locate wires, trace wires on PCBs, and to locate live wires behind the walls without touching them. The circuit uses three transistors

The $9 Quasi-duino (Almost-duino)

Leave a Comment / Circuits / Ibrar Ayyub

Do you currently have an Arduino and want to make it smaller for cheap? The Quasi-duino is for you (Italian for almost-duino). This makes a functional “almost” Arduino, in a very small form factor using the narcoleptic library for pico-power operations on a pico-space breadboard. This ‘ible will use Arduino 1.0. All of your Arduino
