Lesson 13-Infrared Sensor

An infrared sensor : Is  an electronic device, that emits in order to sense some aspects of the surroundings. An IR sensor can measure the heat of an object as well as detects the motion. These types of sensors measures only infrared radiation, rather than emitting it...

Lesson 12 Interfacing with PC

This tutorial, we'll interface Playme with PC. By connecting Playme to PC, we can send messages from the Robot to the computer and from computer to the Robot. This leads to many interesting things which can be done with playme such as creating a light meter or...

Lesson 11 Light Meter

Light dependent resistor is a sensor which is commonly used to detect presence of light. It is used in many experiments for detection purpose, as a burglar alarm. Its value depends on light intensity. It is a type of resistor whose resistance whose value increases...

Lesson 10 Ultrasonic Sensor Measuring Distance

An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. Ultrasonic sensors emit short, high-frequency sound pulses at regular intervals. These propagate in the air at the velocity of sound. If they strike an object, then they...

Lesson 9 Sending Messages On Computer

In this lesson we are going to send message on computer screen using play me. For this we are using Serial communication. It is used for communication between the Controller board and a computer or other devices. In our life we are doing communication it is like...

Lesson 8 Buzzer Program

A buzzer is a piezoelectric audio signaling device. A piezo electric buzzer can be driven by any small DC voltage to generate audio tone. A click, beep, or ring can indicate that a buzzer is sounding. Piezoelectric effect is the ability of certain materials to...

Lesson 7 TV Remote Sensor

Television is an effective and popular medium through which we can get information as well as entertainment. We can get information about things which are happening in world. We are changing channels through its Remote and get connected to different information. When...

Lesson 6 Sound Sensors

Sensors  are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A sensor converts the physical parameter  into a signal which can be measured electrically. There are many types of sensors like temperature, sound...

Lesson 5-Tri Color LED

Tri-Color LED: In previous lessons we have seen Light emitting diode on playme it is commonly known as Used LED1 and User LED2. These are single color LEDs which can give only one color when it turn ON. It may be RED,GREEN,BLUE etc. Tri-color LEDs are having three...

Lesson 4 On Board Switch

Switches are an important part of most electronic circuits. Switches are mechanical devices with two or more leads (or terminals) that are internally connected to metal contacts.   The simplest case, most circuits contain an on/off switch. In this lesson we will learn...

Lesson 1-Meet Playme

Our world is filled with machines and robots everywhere. Now we are using machines, robotics for many things like manufacturing any product, house hold appliances. In near future robotics will every where to do any kind of work. Playme a programmable robot is an...

Lesson 3 Robot Movement Control

In this lesson we are going to move robot in different directions such as Forward, Reverse Left, Right along with stop condition. Before starting actual program lets learn about basics of Robot Movement. Humans are having legs which are for walking purpose. Like...
