The Arduino connects to a device such as a PC or Raspberry Pi via USB, emulating a serial port. The Arduino outputs the temperature in °C on the serial port. The value is decimal, with 4 decimal ...

The newly released Arduino Leonardo has a few very interesting features, most notably the ability to act as a USB keyboard and mouse thanks to the new ATmega 32U4 microcontroller. This feature isn&… ...

So he tried his hand with some really small SMD parts by building this USB to serial Arduino programmer. The chip he went with isn’t the FTDI part we’re used to. Instead of using an FT232RL ...

This Arduino sketch reads the gas concentration of CO2 and LPG (Liquified Petroleum Gas) values from two sensors, the MQ-135 and MQ-2, and then communicates the values to ROS using the following ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

TSL25911 Sensor Module Pinout. The TSL25911 sensor module has a total of 5 pins. Two power pins, one interrupt pin, and two I2C pins. The pinout of the module is as follows: VCC - Provides power for ...

Arduino explains a little more : “the Arduino USB Host Shield is based on the MAX3421E, which is a USB peripheral/host controller containing the digital logic and analog circuitry necessary to ...

Temperature Controlled Fan Circuit Diagram. The complete circuit to build the temperature controlled fan using arduino and lm35 project is given below, we have used fritzing software for making most ...
