This article shows you how to design a high-power motor driver for Bluetooth Controlled Robot using Arduino and relay. Previously, we had posted an Arduino-based Bluetooth-controlled car designed around L293D motor driver IC. There is some limitation of the L293D motor driver IC i.e. output current is limited to 600mA. What if you wish to drive a DC motor that consumes more than 1A? Let’s say 5A. For this, you need a more powerful circuit that delivers appropriate power to the motor. So, here you will learn how to make…

Pause and Resume Arduino Program using Switch
Arduino is an open source and become famous in very short time, due to its powerful features and simplicity. Arduino comes as boon for inventor, artist etc. One can make their own system without having much knowledge about core electronics and assembly programming. In this article you will learn how to pause the code and resume using a push button switch. Sometime, we want our code to run only when user do some action like to press switch of get some value of sensor. Few years back while making game…
Read MoreArduino Based Caller ID for Bike
This article shows you how to make caller ID for two wheeler’s i.e. bike or scooter. This caller ID display cell phone number when any one call you or when you call anyone while riding bike or scooter. Sometime It is difficult to identify the caller while riding two-wheeler vehicles because usually we keep our mobile either in pocket or in bag. Sometime even we get confused whether the vibration is of vehicle or of mobile. By using this simple device one can know about caller and can easily distinguished…
Read MoreArduino Color Sensor Project using TCS230
This article shows you how to make arduino color sensor project using TCS230 color sensor. This project can detect almost all color according to their wave length and display it on 16×2 LCD. If we talk about the application of this project, you can use in color shorting or color matching projects, line following robot (if path is other than black and white), multi-color strip reading etc. What is TCS230 Color Sensor? This module consists 8×8 array of photodiode which detect the color and produce corresponding frequency (Square wave). So,…
Read MoreArduino Alarm Clock with Time Setting
In the post-Arduino alarm clock with time setting you will learn to make a digital clock using the RTC DS3231 module with alarm and temperature indication facility. Previously, we had already posted various types of clock circuits using Arduino and RTC DS3231 like “Arduino NTP Clock using NodeMCU and DS3231”, “Arduino Digital Clock using DS3231 Pi Module“. Before starting to circuit part and software code part let’s see its features: Features of Arduino alarm clock with time setting Display date and time (day and second indication). Alarm time setting Display…
Read MoreArduino MOSFET LED Driver Circuit
In the tutorial Arduino MOSFET LED driver circuit, you will learn to make your MOSFET Driver for any higher power appliance like LED Strip, high power DC motor, etc. We all know that we need a driver circuit to control high-power appliances like DC motors, electrical appliances, etc. So, here we are using MOSFET to control the operation of the LED strip. If you want to know more about MOSFET, its type, Symbol, application, and characteristic curve please do read the previous article on MOSFET | Types of MOSFET |…
Read MoreArduino NTP Clock using NodeMCU and DS3231
In the tutorial Arduino NTP Clock using NodeMCU and DS3231, you will learn to make an accurate clock using the RTC module and NTP server. This circuit automatically updates the time of the RTC module from the network time protocol server. RTC module shows some time delay after some days/week, this is due to temperatures dependent oscillator used in this module. The external oscillator is more prone to temperature than an internal oscillator. DS3231 module has an internal oscillator that is less prone to temperature and humidity but still has…
Read MoreTop 50 Arduino Based Projects
Top 50 Arduino Based Projects: The popularity of Arduino Platform is at most because of its user friendly interface, easy to program, cheap, small size. For electronic hobbyist arduino platform become dream come true due to its plug and play option. Thus, we are going to compile Top 50 Arduino Based Projects posted in bestengineeringprojects.com. This project list include all those popular arduino based project posted in this website. The impact of arduino platform is felt not only in all branch science and engineering but in the life of ordinary…
Read MoreAppliance Control using IOT and AI Chatbot
IoT (Internet of thing) is one of the burning topics among electronic hobbyists and students due to its various advantage. There are many ways/devices with which you can interface your appliance with the internet, NODE MCU is one of them. Node MCU is very much popular due to its various advantage. Some of them are listed below. Thus we are going to make Appliance Control using IoT and AI Chatbot using NodeMCU. Smaller size and breadboard friendly Hardware and pinout are more like Arduino. Support API in Nodejs style thus…
Read More12V Lead Acid Battery Charger Circuit
There are lots of 12V Lead Acid Battery Charger Circuit available over the internet but does not include a battery status indicator. If you wish to know the status of the battery like dead, charged, or charging you need an extra circuit. In order to solve these problems, we combined three different circuits and hence do three different dedicated jobs like charging the battery, indicating the status of the battery, and also have a dedicated port for variable power supply connector of bench power supply in case you need. This…
