In the Atmega 32u4 Based USB Controlled LED Series Project, it was demonstrated how to use control transfer to receive data from computer to the peripheral. In this project, it will be demonstrated to transfer data from microcontroller to the host computer. For this, the device will be configured as HID Class Device again. An

Throughout this USB series, different types of USB devices have been designed and developed. These devices were enumerating with the host computer and then were using Class Specific transfers for further USB communication. Like the Keyboard, Mouse and joystick devices were using interrupt transfers for their operations after enumeration. Similarly, the audio class devices were

In this project, a device will be designed that will read analog data from any analog sensor and will send the digitized form of that data to a personal computer on USB interface. On PC, a desktop application will store the data in an excel spreadsheet therefore performing the data logging. For this, the device
