Learn — CAROBOT

In this article, we will explain how to use the MIT APP INVENTOR using the example of the Car robot from a previous post in which we learned how to program and control a robot through Bluetooth.   The MIT APP INVENTOR is an easy-to-use cloud-based application that allows us to quickly develop an android application. We’ll use it to create a controller app for the robot. Go to the MIT App Inventor website and press “Create Apps!” to start our project :)   After naming the project, we are going to design the layout of our app. The designer gives...

In this article, we will show you how to program the robot car so it can be connected by Bluetooth and create an android application to control it using MIT App Inventor. Take a look at this previous post on how to build a robot car.   Parts Arduino Mega R3 CAROBOT Motor Driver and Servo Shield   Chassis Battery Jumper wires Soldering iron   Arduino IDE Have an Android device with you. We will use it later to control the car's action.   Wiring In addition to the pin set up for the Arduino from the previous post, we will use...

The CAROBOT Motor Shield allows you to easily control motor direction and speed using an Arduino. By allowing you to simply address Arduino pins, it makes it very simple to incorporate a motor into your project. It also allows you to be able to power a motor with a separate power supply of up to 12v. For all of these reasons, this motor shield is a popular device that is commonly used in projects, such as robot cars, and much more.    In this article, we will talk about the setup and operation of the CAROBOT Motor shield with Arduino. ...

The HC-SR04 ultrasonic sensor module is a very popular module for measuring distance or any other purposes. It emits an ultrasound signal at about 40 000 Hz which travels through the air and if there is an object or obstacle along its path, the sound will bounce back to the module. In this article, we will talk about how to wire and set up the module for operation with an Arduino Board.   Wiring  Most HC-SR04 modules operate at 5V and gives out digital outputs. For this project, we will be using the HC-SR04 Ultrasonic Sensor module we carry in our shop. This module consists...

In this article, we will guide you on making a robot car that can follow a line. We will be using the parts that we carry in our shop.  We will be using CAROBOT Motor Driver and Servo Shield to make connected Motors to Arduino UNO. The shield separate the Uno's PWM digital pins (3,5,6,9,10,11) and the non-PWM digital pins (2,4,7,8,12,13) for easy identification. Furthermore, it provides a 5V and GND rail for easy connections. The Motor and Shield shield is equipped with an L298N H-Bridge Motor Driver. This allows the shield to drive two DC motors.  We will also be using...
