The first successful assessment of PID control theory was practically verified in the field of automatic steering systems for ships, way back around the year 1920. After this it was applied in various industrial automatic process controls requiring optimized and accurate manufacturing output specifications. For manufacturing units PID was popularly implemented for achieving precise pneumatic […]
How to Design a Flyback Converter – Comprehensive Tutorial
A flyback configuration is the preferred topology in SMPS application designs mainly because it guarantees complete isolation of the output DC from the input mains AC. Other features include low manufacturing cost, simpler design and uncomplicated implementation. The low current DCM version of flyback converters which include output specification lower than 50 watt are more […]
Ultrasonic Wireless Water Level Indicator Using Arduino – Solar Powered
In this post we are going to construct a ultrasonic based solar powered wireless water level indicator using Arduino in which the Arduinos would be transmitting and receiving at 2.4 GHz wireless frequency. We will be detecting the water level in the tank using ultasonics instead of traditional electrode method. By Girish Radhakrishnan Overview Water […]
