This Module can be used in a hand gesture controlled Robot, wheelchair, earthquake detection system, Self-balancing Robot, the self-balancing. The MPU6050 always acts as a slave to the Arduino with the SDA and SCL pins connected to the I2C bus. Arduino has quite a few built-in libraries.Necessary cookies are absolutely essential for the website to function properly. The MPU6050 communicates with the Arduino through the I2C protocol. Then you're using the Serial() library built in to Arduino. You may not realize it, but you're probably already using libraries! If you've used: Serial.print("Hello world!") Infrared Remote is a great library for reading signals from IR remotes and controlling IR remote based things like TVs and sound systems.It’s great for non-contact capacitive switches and field sensing. Capacitive Sensor is the library we covered in this tutorial.EEPROM is a built-in library that allows users to read and store settings within the non-volatile memory of the ATmega328.

MP3Shield is a great example of a customer of SparkFun taking complex example code and creating a very good library to make the device easier to use.

Great for datalogging! Be sure to checkout all the examples included with the library.

Sdfat is a very good library that allows you to read and write files to SD cards.

SevSeg is a library we wrote to make controlling 7-segment displays easier.

TinyGPS is the gold standard for interfacing to GPS modules.

If you're looking for some great libraries to get started with, here are some of our favorites: Make sure you have a good understanding of the following concepts before getting any further into this tutorial.

This tutorial will show you how to install a library in Arduino v1.0.5 but should apply for many past, present, and future versions of Arduino. There are thousands of libraries out there! And luckily it’s pretty easy to install them. Libraries make complex tasks easier so that we can focus on larger projects. The m圜apPad.capacitiveSensor() takes care of all the heavy lifting and the senseReading variable contains the value sensed from our capacitive pad. SenseReading = m圜apPad.capacitiveSensor(30) While ( (*rIn & rBit) & (total = CS_Timeout_Millis)Īll that code can be replaced with a much easier to use and understand statement such as: language:c *rReg |= rBit // set pin to OUTPUT - pin is now HIGH AND OUTPUT *rOut |= rBit // set receive pin HIGH - turns on pullup set receive pin HIGH briefly to charge up fully While ( !(*rIn & rBit) & (total CS_Timeout_Millis) *rReg |= rBit // set pin to OUTPUT - pin is now LOW AND OUTPUT *rOut &= ~rBit // set receivePin Register low to make sure pullups are off *rReg &= ~rBit // set receivePin to input

*sOut &= ~sBit // set Send Pin Register low The CapacitiveSensor library takes care of everything so that we don’t have to write code like this: language:c We can write the code from scratch, or we can stand on the shoulders of great people who are smarter than we are.Ĭapacitive touch sensing is a very popular interface. For example, capacitive sensing takes difficult timing and pulsing of digital pins. Arduino users have written lots of exciting add-ons for Arduino. Arduino libraries take a complex task and boil it down to simple to use functions.
