IO Expansion Shield for Arduino V7.1 x1.

We will use Arduino to control module speed.

Interface type: Gravity 3-pin digital sensor interface.

And the speed control could be realized with PWM　signal.

Gravity 130 DC motor is a very interesting module, the module does not need additional motor driver board, you can use Arduino board to drive it easily. Get Gravity: Digital Relay Module (Arduino & Raspberry Pi Compatible) from DFRobot Store or DFRobot Distributor.Gravity_130_DC_Motor_SKU_DFR0411-DFRobot In brief, a relay is an electronic switch, which can use a small voltage to control high voltage or high current.įor any questions, advice or cool ideas to share, please visit the DFRobot Forum. when the water level reaches the metal block A, the circuit will be bright red light, otherwise the circuit will be a green light.Ī. The advantage of using relay control circuit is to control high voltage with low voltage input.Īs shown below, this is a schematic diagram of the water level alarm. Therefore, the relay is used to control the operation of the circuit breaker switch. When the electromagnet is powered off, the electromagnet loses magnetism, and the circuit is switched off. When the relay works, the electromagnetic switches off, which makes the circuit closed. NO terminal is disconnected from the COM port, and the LED is OFF. When the module gets HIGH signal, NO terminal is connected with the COM port, and the LED is ON.The LED will change it's state every seconds,and you will hear a loud of pop at the same time.***********Notice and Trouble shooting***************ġ.Be ware of electric shock and burn out the circuit board.Ģ.The input voltage of this module is 2.8 ~ 5.5V.ĭigitalWrite(RelayPin, HIGH) //Turn on relayĭigitalWrite(RelayPin, LOW) //Turn off relay

DFROBOT GRAVITY CIRCUIT HOW TO

This example shows how to use 3V Relay Module(DFR0473).Īll above must be included in any redistribution Arduino IDE, Click to Download Arduino IDE from Arduino®.LED lights (or other electrical equipment).

1.5V AA battery (or other power supply) x2.

Rating Load: Max Switching Power: 300W.

Input Signal: High Level (≥2.8V) Low Level (≤0.5V).

Need to check the circuit before power on, in order to prevent short circuit.ĭo not use this module in a system involving personal safety. Please do not put it on the conductive object when in normal use. The module uses a Gravity-3 pin interface, which requires no soldering for convenient plug and play usage.Ĭhildren under 8 years old do not use this module.

Terminals include normally open (NO) and normally closed (NC). An on-board indicator LED demonstrates the relay’s state. It can handle up to 10A current and mechanical parts are guaranteed up to 100 million uses. In our tests, once it reaches 2.8~5.5V, it can also support 1.8V devices.ĭFRobot’s Digital Relay Module uses a high quality 3V relay. In addition, the module has a wide range of power inputs. It is specially designed for low-voltage devices and works well under 3.3V power supplies, just like the Raspberry Pi relay board. Introducing the Gravity Digital Relay Module – the latest addition to DFRobot’s Gravity series! This module is a little different to the other relays in our store - not only is it compatible with 5V Arduino boards, but also with Raspberry Pi, BBB (BeagleBoard Black), mbed, Intel Joule, Arduino 101 and other 3.3V devices.
