We use an ADC very frequently. Input range of an ADC is normally 0 to +5V. Atmega AVRs contain typically many 10bit ADC channels (6 for atmega8 to atmega328 and 8 channels for atmega8535). The designer faces a problem when … Continue reading
TINAH can be used to indicate room temperature on 2×16 LCD display.
A timer can be very cost effective if we use LEds to show numbers. BinT uses simple LEDs to display a number in binary format.
This article describes a simple timer using Arduino.
A simple security alarm was developed in two consecutive workshops at Techno e School.
Lead acid battery over voltage protector It allows the charger to charge the battery such that,
This video shows you how a simple robotic arm works.
Abstract: This project make use of an LDR (light dependent resistor) to sense light and darkness and control the bright white LED.
Abstract: To send logical zero and logical one, at a long distance, this method is adopted.
Abstract: This simple timer makes the output LED “on” for some time and then goes “off”. The chip NE555 (or equivalent) is off the shelf available and is low cost.
