PINOUT: http://img.banggood.com/file/products/20171225211813PINOUT-MOSFETRelay.pdf Schematic: http://img.banggood.com/file/products/20171225211906Schematic-MOSFETRelay.pdf Feature: If you need to control the DC power, a MOSFET is what you need. This is a very common MOSFET with very low on-resistance and a control voltage (aka gate voltage) that is compatible with any 5V microcontroller or mechanical switch. This allows you to control high-power devices with very low-power control mechanisms. This board has an Opto-isolator to protect your microcontroller from high currents. We also left more space, if you need to install the heat sink for a transistor. Operating voltage: 4.5V-24V (peak 36V) 50W / N-chanel MOSFET Package includes: 1 x Transistor MOSFET Module

Feature: We all know what an AC dimmer is; for those who don’t, it’s a kind of a circuit which can control the amount of AC voltage to be given to any device. You can see them in a fan regulator or a light dimmer switch. It's good for a smart home if you need to turn the lighting on and off slowly. The lamp is slow damped, this creates a pleasant effect. Also can control AC/DC motor, electric pump, tools. Pulse Skip Modulation: Another way of doing this is by Pulse Skip Modulation. With PSM, one or more full cycles (sinuswaves) are transferred to the load and then one or more cycles are not. Though effective, it is not a good way to dim lights as there is a chance for flickering. Though it might be tempting, in PSM one should always allow a full sinuswave to be passed to the load, not a half sinus as in that case the load will be fed factually from DC which is not a good thing for most AC loads. The difference between leading edge cutting and PSM is mainly in the software: in both cases one will need a circuit that detects the zero crossing and that can control a triac. A circuit that can do this is easy to build: The zero crossing is directly derived from the rectified mains AC lines – via an optocoupler of course- and gives a signal every time the wave goes through zero. Because the sine wave first goes through double phased rectification, the zero-crossing signal is given regardless whether the sinus wave goes up through zero or down through zero. This signal then can be used to trigger an interrupt in the Arduino. Package includes: 1 x AC Light Dimmer Module

Feature: Compatible with Arduino Uno R3 board. Built on the ATmega328 microcontroller and USB-UART interface chip CH340G. Board for functionality similar to the Arduino Uno (ATmega 28). It is a budget, but the same stable, and uses the original chips ATmega328 (16 MHz). The board used the chip CH340G as converter UART-USB. Chip CH340G - is a budget solution. When you work in the frequency 12Mhz, giving a stable result of data exchange (need install drivers to computer). Uno R3 CH340G/ATmega328 - connects to the computer via microUSB cable (used for almost all Android smartphones). You can supply power to board through a MicroUSB connector or DC power socket. The voltage regulator (LDO) can deal with incoming voltage from 6V to 12V DC. Output current for 5V - about 800mA, for 3.3V - about 180mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects. Package includes: 1 x Uno R3 board
