7 Watt LED Driver SMPS Circuit – Transformerless, Current Controlled

The presented 7 watt LED driver circuit is an SMPS based non-isolated, transformerless circuit which ensures a safe current controlled output for the attached LED, it is very affordable to build without  involving complex transformer winding. The aim behind the design of the IC TPS92310 (from TEXAS INSTRUMENTS) is to offer a constant current line … Read more

LED Strip Light Controller Using Arduino

In this post we are going to construct LED strip controller circuit using Arduino, which can turn ON/OFF and decrease/increase brightness of LEDs using ordinary IR (Infrared) remote. By Girish Radhakrishnan   What is LED Strip Light? (For noobs) If you are not familiar with LED strip lights, let’s understand what it is. LED strips … Read more
