Using the Makey Makey - Standard Kit you can make anything into a key just by connecting a few alligator clips. It tricks your computer into thinking almost anything is a key.You may be the greatest living banana-pianist, but how will you ever know if you don't make yourself a banana piano? Good news, that project and countless others are easier than you think they are with MaKey MaKey.
MCP23017 16-BIT I/O Expander Serial I2C Interface Module Add another 16 pins to your microcontroller . The MCP23017 uses two i2c pins (these can be shared with other i2c devices), and in exchange gives you 16 general purpose pins.
This is MCP2515 CAN Module TJA1050 Receiver SPI 51 Single Chip Program Routine Arduino with this module, you will easy to control any CAN Bus device by SPI interface with your MCU, such as Arduino UNO and Compatible with Arduino based micro-controller projects.
