This post describes how to use the Keyes IR Receiver Module in a practical application. The setup used in this experiment is shown in the picture to the right and it includes Arduino UNO card (hidden under an Ethernet shield), a display module JY-LKM1638, a Keyes IR Receiver module and a remote… Read more »
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… Read more »
The Arduino robot kit includes a Bluetooth-Serial Converter Module JY-MCU (mine says BT_BOARD V1.04). After some Google search, I found information about how to setup this module. See this for example, which also has a good link about how to change the default configuration of the module. In this post,… Read more »
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… Read more »
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… Read more »
I have created this wiring diagram for the connections between the motor controller, motors, and sensor shield. I’ll update it later to include other components. And here is an update that includes the servo motor and the range sensor. And here are the detailed pin assignments for all modules: Pin… Read more »
JSim is a Java-based discrete event simulator of an M/M/s queue system. The source includes a library of classes that can be used to modify the application to simulate other types of queue systems as well. JSim source files can be downloaded from Github. A brief description of the main… Read more »
Thomas Schelling showed, in 1971, that a small preference for one’s neighbors to be of the same race could lead to total segregation. This model is used as an example to show how such individual behaviour can bring about such undesirable social conventions without the need for evil master plan… Read more »
Once the motors were connected to the motor controller (see previous post), I started working on writing the code for basic robot movement. The basic motor commands are: onFwd/onRev: move each motor independently in the forward or reverse direction off/stop: stop either motor gradually (float) or abruptly (break) fwdRight/fwdLeft: turn the robot by running the two… Read more »
