Most project of Arduino may need more than two voltage supply. When feed with from 4.5-35V, this power shield able to provide a voltage range from 1.25-12V with 3A peak current.
"Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
The DFRduino Nano USB Microcontroller V3.1 (ATMega 328) is a breadboard ready version of the Arduino mini with integrated USB. The Nano has everything that the Diecimila has (electronically) with more analog input pins and an on-board +5V AREF jumper. The Nano automatically senses and switches to the higher power supply, so there is no need for a power select jumper.
Combines the power of screw shield and prototyping shield. This Proto Screw shield offers a better way to do prototyping. The Screw terminal can be screwed directly to the terminal on the thread and is reliable and convenient. It can be plugged into the Arduino controller. You can use this shield to save yourself from the bad port connection. Feel secure with this arduino-compatible screw shield.
DFRduino Mega1280 is a microcontroller board based on the ATmega1280. It has 54 digital input/output pins, 16 analog inputs, 4 UARTs (hardware serial ports), a 16...
The DFRobot Single Relay blocks the number of electronic modules. It can be used in interactive projects. It can also be used to control the lighting, electrical and other equipments. The modular design makes it easy to expand with the Arduino board (not included). The Relay output state by a light-emitting diode. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.
This is a digital tilt switch. It can be used as a simple tilt sensor. Simple plug to our IO/Sensor Expansion board, you can make amazing interactive projects.
A relay is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in automatic control circuit.It is actually "automatic switch" ,using a small electric current to control a larger current.
FireBeetle ESP32-E, specially designed for IoT, is an ESP-WROOM-32E-based main controller board with dual-core chips. It supports WiFi and Bluetooth dual-mode communication...
Want to connect several Seeed Studio Grove modules to your Arduino board? The Arduino MKR CONNECTOR CARRIER is the perfect companion for Arduino MKR boards and a Grove ecosystem.
This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded.
This is a new version of the FTDI breakout board features an Atmega8U2 programmed as a USB-to-serial converter, the same chip found on the Arduino Uno.
