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.
This project make use of an LDR (light dependent resistor) to sense light and darkness and control the bright white LED. वाचन सुरू ठेवा “Light sensor”
To send logical zero and logical one, at a long distance, this method is adopted. वाचन सुरू ठेवा “Frequency shift keying”
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. वाचन सुरू ठेवा “Simple timer”
In this project, a simple variable voltage regulator is implemented. LM317 is used to regulate the output voltage. वाचन सुरू ठेवा “Voltage Regulator”
This project describes a circuit for a siren. IC 555 is used so that the circuit components are low cost and available off the shelf. वाचन सुरू ठेवा “A Siren”
