Arduino RGB Flowing Sequential Light Circuit

Last Updated on December 5, 2024 by Swagatam Leave a Comment

rgb 3

This Arduino RGB sequential light generator circuit will generate a smooth flowing red, green blue pattern over the connected RGB LED. The LED used here is a four pin 30mA RGB LED, common anode type, meaning the common pin for this LED will need to be assigned a continuous positive for the required operations. The […]

Make this Temperature Indicator Circuit with Sequential LED Display

Last Updated on December 31, 2018 by Swagatam 2 Comments

temperatureindicatorcircuitwithLEDdisplay

In some of my earlier articles we have seen a few simple and interesting temperature indicator circuits, in this article we will try to upgrade one of them into a sequential form. All these circuits are useful in some or the other ways, however these are not equipped with  step wise temperature level indicator arrangement […]
