This simple direction pointer circuit is made with the help of an IC CD7404 with few more commonly used components. CD7404 is the most commonly used Complementary Metal Oxide Semiconductor (CMOS) chip. It comes in a 14 pin Dual Inline Package (DIP). It has small notch on one side which identifies as pin 1. It consists of 6 independent NOT gate on a single chip. Each gate has 1 inputs and 1 output. Working voltage range of IC is from 5V to 16V. It can deliver approx.10mA at 12V but this can be reduced as power supply voltage reduces.
