What is a shielded relay?
The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino/Crowduino through digital IOs with an external 6.5~12V DC supply.
What is a Relay Shield used for?
The Relay Shield provides four high-quality relays that can control high current loads to Arduino / Seeeduino boards. It also provides NO (Normally Open) / NC (Normally Closed) interface. It could be a nice solution for controlling devices that could not be directly controlled by Arduino’s Digital I/Os.
What is relay Shield for Arduino?
The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino’s digital IOs, due to the current and voltage limits of the controller. Four LEDs indicate the on/off state of each relay.
How does a relay shield work?
The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel. Four LEDs indicate the on/off state of each relay.
What is motor shield?
The Motor Shield is a driver module for motors that allows you to use Arduino to control the working speed and direction of the motor. Based on the Dual Full-Bridge Drive Chip L298, it is able to drive two DC motors or a step motor.
What is a 5V relay used for?
A 5v relay is an automatic switch that is commonly used in an automatic control circuit and to control a high-current using a low-current signal. The input voltage of the relay signal ranges from 0 to 5V.
How many relays can a DFRobot relay Shield control?
The DFRobot Relay shield V2.1 is capable of controlling 4 relays. The max switching power is DC 90W or AC 360VA. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. With the built in xbee socket, it can be wirelessly controlled via Xbee/bluetooth/WPM.
What kind of power does a relay shield need?
The max switching power is DC 90W or AC 360VA. It is possible to control the Relay shield through Arduino/DFRduino using digital IOs with external 7 to 12V supply. With the built in xbee socket, it can be wirelessly controlled via Xbee/bluetooth/WPM. This makes it an ideal solution for automation and robotics.
How do you reverse swap a motor in a Deek?
To go in reverse swap the outputs, write a 1 to the first pin and a 0 to the other. If both pins are the same (both 1 or both 0) the motor is stopped. Connect a PWM pin to EN1 to control the speed of motor 1 and to EN2 to control motor 2 (after removing jumpers).
