Hello makers in this post we’ll learn how to make LM317 based variable voltage regulator circuit module. So a obvious question come in your mind what is variable voltage regulator circuit is ? A circuit which regulate the voltage in some range like 5V to 24V dc with respect to constant input voltage is what … Read more
Hello makers in this post we’ll learn how we can control high rating 755 DC motor with arduino using TIP122 Whenever we need to run a DC motor in our arduino project, we cannot connect it directly to the digital pins of arduino board because the maximum current rating of digital pin is 40mA. and … Read more
In this article we will see how can we build a darkness sensor by using LDR sensor. This sensor detect light falling on it and change it resistance accordingly.This change in resistance of LDR detect by a circuit. Which turn led ON When light is not falling on LDR and turn LED OFF when light … Read more
