Controlling AC light using Arduino with relay module

I'm Ostin,I ll demonstrate how to control a AC light with Arduino using relay module.It is a simple project and also very dangerous as we are going to deal with high voltage 220v . Do not attempt if you are a amateur in dealing with high voltage. I'll answer few basic questions, which hits when you are novice! Buy Latching Relays SPST-NC, SPST-NO DIN Rail Panel Mount Latching Relay, 16 A, 230V ac Finder online from RS for next day delivery.

16A Step Relays - 20 Series The 20 Series are available as DPST-NO or SPST-NO + SPST-NC step relays.

On each successive energisation of the relay coil the contacts will change state thus providing a step or "flip flop" sequence of operation. An override test button allows manual advancement of the step sequence and individual mechanical flags provide visual indication of contact status. ,Typical applications would include the control of lighting where push on push off or sequential operation is required, automatic opening and closing of doors, gates, etc. Use in portable or battery powered equipment requiring contact status to be maintained without continuous supply to the coil and functions where manual override operation is desirable.

Solid State Relay [COM01281P] Feedback & Support Grove - Solid State Relay Out Of Stock Grove – Solid State Relay is a non-contact electronic switch module that has relay features.

Solid State Relay [COM01281P]

Based on SHARP S208T02, it has a maximum output of 250VAC/4A, with a switching speed less than 10ms. This module is equipped with acrylic base and a 3D-printed protection insulation shield, for user’s safety. Features Compatible with both 3.3V and 5V control level Low switching latency(≤10ms) LED on-state indicator Featured radiator provide better stability Acrylic base and insulation paper increase safety performance Grove compatible Application Ideas Operations that require low-latency switching, e.g. stage light control Devices that require high stability, e.g. medical devices, traffic signals Situations that require explosion-proof, anticorrosion, moisture-proof, e.g. coal, chemical industries.

For all Grove users (especially beginners), we provide you guidance PDF documents. Documents Overview Designer: Seeed Studio Weight: 49 g. 2-Coil Latching Relay [103020010] This module is based on 2-Coil Latching Relay.

2-Coil Latching Relay [103020010]

Contrast to the ordinary relay, this latching relay do not need continuous power to keep the state, only a rising/falling pulse is needed to change the work state. Even the power can be removed when the work state do not need to change, making this module especially suitable for low-power projects. Features. SPDT Relay(30A) [ACT05161P] The SPDT Relay(30A) is a high quality Single Pole Double Throw Relay(SPDT).The Relay consist of a coil, 1 common terminal, 1 normally closed terminal, and one normally open terminal.

SPDT Relay(30A) [ACT05161P]

When the coil of the relay is at rest (not energized), the common terminal and the normally closed terminal have continuity. When the coil is energized, the common terminal and the normally open terminal have continuity.This relay's coil is rated up to 5V and the contact is rated up to 30A (@250VAC, 30VDC). Buy Relay shield V2.0 [SLD01101P] Planned Shipment Date: Nov 30 , 2014 The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current.

Which means it could be a nice solution for controlling devices that couldn’t be directly controlled by Arduino’s Digital I/Os. Standardized shield form factor enables smoothly connection with the Arduino. The shield also has four dynamic indicators show the on/off state of each relay. Note: Headers of this product is shipped unsoldered. Features Arduino/Seeeduino compatible Standardized shape design Working status indicators for each relay High quality relays Provides NO/NC interfaces Cautions Place 2 layers of electrical tape on the top of theArduino's usb connector.

Self-powered Contiki Power Sensor Wins IPSO 2013 Challenge

That's exactly what the Contiki-based winner of the IPSO 2013 challenge does. Just clip on the sensor on cord and see the data from anywhere in the world – the sensor sends the measurements wirelessly and securely across the Internet. Best of all: no batteries need to be replaced, ever, as the sensor is completely self-powered. The wireless power sensor, developed by Redwire Consulting, Boston, MA, won the IPSO 2013 Challenge last week. Aside the fame and recognition, winning the competition also included a $10000 USD check.
