I want to switch off/on my router with arduino

Other Hardware General Electronics

At first I am totally newbie to electronics and specs and so other geeky stuff, But I want to start learning electronics through making small project that I need so badly. "any advice will be very appreciated"

I want to control my router -switch off/on power cycle- ( TD-W8961ND | 300Mbps Wireless N ADSL2+ Modem Router | TP-Link )

I watch tutorial on youtube which do similar task with "relay board" but I don't know which voltage and amp should I purchase based on my router specs.

Note: my power source is 220v

Does your router use a wallwart?

Yes, and here it is the specs of it "External Power Supply 9VDC/0.85A"

Plug your wallwart into powerswitch tail controlled by the Arduino:

You can always use a relay between the wall wart and the router.

Is why I suggested a PowerSwitch Tail

Power your arduino and router through the same extension lead plugged into the mains. Fit some wheels to the bottom of your arduino and sit your router on top. When you want to disconnect your router you just send power to the motors.

LOL Thank you.

Now all you need to do is figure out how to plug it back in again to turn router on. :confused:

It sounds like a perfect application for a SSR (solid state relay) with the arduino connected to the 0-36V dc
input of the SSR which interrupts the hot lead (L)

The wiring is as follows:
A short custom extension cord is made with a plug

at one end and an OUTLET at the other end with one special modification:
The Neutral and ground are connected directly from the plug to the outlet but the Hot (L) goes from the
plug to one of the SSR screw terminal on AC side . The other screw terminal on the AC side goes to the
Hot (L) of the outlet. The router wall wart plugs into the outlet . The arduino switches the hot lead by controlling the SSR.

HOT HOT-IN HOT-OUT HOT
Neutral Neutral
GND GND

ARDUINO SSR-DC + SSR-DC -
Dig-out Dn Dn
GND GND

9v 1amp is not too much current!

A power transistor would do it, but a SSR or regular mechanical is the easiest option.

Although switching the load on the output of the walwart is an option, it is not the preferred one because
the walwart will still be energized when the lamp is off. It would better to switch the INPUT of the wallwart
rather than the output.
