Product Description: The MPU6050 devices combine a 3-axis gyroscope and a 3-axis accelerometer on the same silicon together with an onboard Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms. The parts’ integrated 9-axis MotionFusion algorithms access external magnetometers or other sensors through an auxiliary master I2C bus, allowing the devices to gather a full set of sensor data without intervention from the system processor. The devices are offered in the same 4x4x0.9 mm QFN footprint and pinout as the current MPU-3000? family of integrated 3-axis gyroscopes, providing a simple upgrade path and making it easy to fit on space constrained boards. The InvenSense Motion Apps Platform that comes with the MPU-6050 abstracts motion-based complexities, offloads sensor management from the operating system and provides a structured set of APIs for application development. For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps) and a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g.

This is an infrared based sensor array which can be used in advanced line following and grid navigation robots. The array has 8 individual sensors placed next to each other. Each sensor has its own digital output and can sense the presence of a line and indicate it with a 5V logic output. On reading the the digital state of the eight sensors, the user can not only detect the line but also get to know how far the center of the robot is from the line. When all sensors sense the line, the robot is on an intersection. Features

• Uses 8 sensors for best resolution.
• Great useful in building fast line following and grid navigating robots.
• Input Voltage: 5V DC.
• Comes with easy to use digital outputs that can be connected directly to microcontrollers.
• The array has mounting holes of 3mm diameter for easy mounting.

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, position limit, etc. In principle, any rate meter simply measures the rate at which some event occurs. Usually this is done by counting the events for a given period of time (integration interval) and then simply dividing the number of events by the time to get the rate.

USB to UART Converter is a very useful tool for Embedded Systems. If you haven’t one, please try to buy it. It will definitely boost development speed of projects which uses UART modules like interfacing GSM, GPS, Bluetooth, Wi-Fi et. By using it we can easily study these modules by sending data directly from your PC and analyzing the received data in your computer display without programming a microcontroller. Here we will use PL2303, one of the most popular USB to UART Converter manufactured by Prolific Technology Inc.

The Leonardo is Arduino’s first development board to use one microcontroller with built-in USB. Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol! It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
