The transistor-controlled relay mentioned above enables you to switch very large amounts of current on or off. This enables you to switch large devices such as your washer/dryer, heater, air conditioner, car starter, among other things on or off with your Arduino. ...
one piggy backed on top of the other, the first one driving the second one. The current amplified by the first transistor is amplified further by the second transistor. This allows a very small voltage to switch a very large voltage. The TIP120 can handle 60v up to 5 amps. These are t...

A MOSFET if very similar to a transistor with one major difference, the MOSFET is a voltage controlled device and a transistor is a current controlled device. You can think of the MOSFET (as with a transistor) as a hose with an in-line valve. By controlling this valve you can determine ...
--(L298N internal transistor switch, low efficiency, high fever, need to add heat sink, bulky, L298N very easy to burn).--Dual 1.5A * 2, the peak current to be 2.5A, built-in thermal protection circuit, do not be afraid motor stall burned, automatic recovery after the temperature ...
Optocouplers are digital switches. They work by using an LED emitter paired with a photo detector transistor. This means they can be used to allow one circuit to switch a separate circuit without having any electrical contact between the two. Basically, if you put a current through pins 1 an...
- 1 x power switch - a couple meters of ethernet cable. Step 1: The Water Part. The valves are very simple to use. They are closed by default and get magically opened by powering their solenoids with 24v AC. I found this transformer on ebay for not very much. 230v AC -> 24v AC...

Once [Brian] got under the hood, he found that it actually has four separate heatsinks: one for the bridge rectifiers and one for each power transistor on the three output channels. The heatsinks are electrically and thermally isolated from each other and change temperature based on the chan...
