Interfacing L298N Motor Driver with Arduino Uno

1 May Interfacing L298N Motor Driver with Arduino Uno In this tutorial we will learn how to interface L298N motror driver with Arduino Uno . You might be thinking why we need L298N for controlling a motor. The answer is very simple, Arduino board or a microcontroller IO pins don’t have enough current/voltage driving capability to drive a motor. For driving the motor in both directions (clockwise and anti-clockwise) we need to use an H-Bridge . Please read our article H-Bridge – DC Motor Driving for more information. L298N is an integrated monolithic circuit with dual H-Bridge. It can be used to rotate the motor in both directions and to control the speed of the motor using PWM technique. Components Required Arduino Uno L298N Motor Driver 12V battery 2x DC Motors Jumper wires L298N Motor Driver Module L298N Motor Driver Connections Explained Specifications Output A, Output B – To connect two motors. Driver Power Input – Board can accept 5V to 35V which will act as the power

E-TECH SOLAR INVERTER SOLUTION

DEEP CYCLE BATTERIES The reason many projects fail can mostly be put at the door step of batteries due to inadequate charging and low charge/discharge cycles. Our batteries are among the very top 3 in the industry and capable of undergoing several cycle of up to 5 years @ 20% DOD. Hence, we are confident of giving as much as 2 years warranty for some of our batteries SOLAR SYSTEM FOR DOMESTIC AND INDUSTRIAL USE Many businesses such as hospitals, schools, shopping malls, hotels etc are beginning to embrace solar to completely eliminate unnecessary spending on diesels ……. why not come on board now and earn yourself some carbon credit apart from huge savings in millions of Naira. SOLAR PANEL MODULES Our panels are carefully selected and tested from the very best among the Tier one range of solar panels. We guarantee a sustainable yield for at least 25 years and 15 years warranty Inverter Our hybrid inverter chargers are super-powered with

Using the TLP250 Isolated MOSFET Driver

Using the TLP250 Isolated MOSFET Driver - Explanation and Example Circuits I’ve already shown how to drive an N-channel MOSFET (or even an IGBT) in both high-side and low-side configurations in a multitude of ways. I’ve also explained the principles of driving the MOSFETs in these configurations. The dedicated drivers I’ve shown so far are the TC427 and IR2110. Some people have requested me to write up on MOSFET drive using the very popular TLP250. And I’ll explain that here. The TLP250, like any driver, has an input stage, an output stage and a power supply connection. What’s special about the TLP250 is that the TLP250 is an optically isolated driver, meaning that the input and output are “optically isolated”. The isolation is optical – the input stage is an LED and the receiving output stage is light sensitive (think “photodetector”). Before delving any further, let’s look at the pin configuration and the truth table. Fig. 1 - TLP250 Pin Configuration Fig.
