Arduino robot kit – Bluetooth Remote Control

Arduino robot kit – Bluetooth Remote Control
The Amarino app mentioned used in the previous post translates the sensor inputs of an Android phone ( and other events such as SMS messages) into messages sent to the Arduino via Bluetooth. In this post, I will use the orientation sensor on my phone to drive the Arduino Robot. The orientation sensor on the Andriod platform provides yaw, ...

Arduino robot kit – Autonomous Motion

Arduino robot kit – Autonomous Motion
At this point, we can put the motion and the range sensing capabilities of the robot to good use. For autonomous motion (no remote control), the robot needs to use its range sensor to detect obstacles and avoid them by turning to another direction. The next sketch does that by moving the robot forward while reading ...

Arduino Relay Module

Arduino Relay Module
A relay can be used, for example, to control the power to a small home appliance. I used this Arduino 2-Channel Relay Module (AC 250V 10A / DC 30V 10A) to control multiple appliances by replacing the mechanical on/off switch of a regular power bar with this relay. The control of the relay by an Arduino microcontroller is straight forward. ...
