Do you have a GitHub project? Now you can sync your releases automatically with SourceForge and take advantage of both platforms.

This is a Delphi project and provides GUI and command line interfaces. The command line version allows control of the relays using various different command line arguments.

The relays allow you to control any 12 volt appliance such as led lights for example. The relay boards are the most common ones available online. They can also process input signals such as switches and sensors. RS modbus contains the source This reflow oven controller was built to control a modified toaster oven for the purpose of doing reflow soldering of printed circuit boards.

The controller was designed and built around an ESPDevKitC development board with ancillary electronics added to complete the controller. The code for the controller was modified extensively from existing Arduino sketches for reflow oven controllers and is PID-algorithm based. The firmware A nice and simple solution to control and test the masla. It provides a schematic or overview to easy switch relays on or off. The USB interface of the devices makes a connection easy.

Written in python and use of pygtk and pyserial it can be used flexible on several platforms. And it's just a example to control the relay -devices to help you write your own program. KMTronic's USB and Serial relay boards are selectable in the configuration menu, other boards can be setup by entering their control commands.

Although primarily designed for irrigation you can use AIC to control a large variety of hardware, for example lighting, heating etc It is envisaged that future implementations of AIC will incorporate rules for more complex device control. Visit the Wiki page for detail. The project aim is to make them as light weight tools that can be directly executed in command prompt without the need of installation. Here is the missing part!

Some example code is listed below. NET example code: Download it here. Visual Basic Calling Parameters: 1. If the function succeeds, the return value will be TRUE. When the function completes successfully, each unique identifier for each USB Relay board found will be placed in a zero terminated string.

Each identifier will be separated by a " ". The string also is ending in a " ". The calling program will have to parse out the identifiers. Example: A C F. Purpose: To poll the Manufacturer specified in the device firmware for a specific device ID.

When the function completes successfully, the buffer will contain a zero terminated character string containing the manufacturer. Purpose: To poll the Product specified in the device firmware for a specific device ID. When the function completes successfully, the buffer will contain a zero terminated character string containing the product string.

Purpose: To poll the Version specified in the device firmware for a specific device ID. When the function completes successfully, the buffer will contain a zero terminated character string containing the version.

When the function completes successfully, the returned buffer contains a series of bytes representing relay status, LEDS enabled, and firmware. See below for an in-depth explanation of the returned bytes.

There are other python modules out there for controlling these relays, however, I needed to be able to get the state as well as set the state, something the other modules didn't offer.

SainSmart 8-Channel Relay Module.I've opened one of the boards and read the specs, but can't find if they are HW etc drivers what ever. It does not have the relay numbers on the circuit board, so I assume it is incorrect? Can someone point me to a correct board? I noted on your gethub page there was additional instruction under "Linux Dependencies".

I have not completed these instructions. Are they necessary? I did not see these on the Node-Red product description page.

I did navigate to the "udev" folder and tried to make a new folder named "rules. I looked up sudo and nano as you suggested. I learned enough to add the rule file as instructed. A complete log of this run can be found in: T That looks like a network issue I think.

Try again to see if it has recovered. I just saw this in the "library": Nice. Just asking. Noobie Function question. I tried with github, but missed that part. I also need help. Also, followed all of the steps on the github link provided by ukmoose.

So, can someone kindly help me to set up your Node considering I have no programming knowledge? Thanks Walter I looked up sudo and nano as you suggested. Appears to be working now.

Latest Stable Release 0. A cheap USB relay available from Ebay with 1,2,4 or 8 relay output. The double throw relay ratings are 10A VAC each. The program is command line only as it is likely to be used by shell scripts.

The package was built for Pidora Fedora 18 using the F20 hidapi source package. The relay modules does not set the USB serial number but has a unique serial when the HID device is queried, the current state of the relays is also sent with the serial.

The usual make, make install dance assuming the hidapi and hidapi-devel packages have been installed. Note that there are two options for the hidapi library: hidapi-hidraw or hidapi-libusb. Different distributions have better results with one or the other. You can also build using Docker. Assuming you have Docker installed only tested with version 18execute the build script:. The usbrelay binary, libusbrelay.

The code needs to access the device. This can be achieved either by running the program with root privileges so sudo is your friend or by putting.

Running the program without arguments will display each module that matches device 16cdf or The program can be invoked with the debug -d or quiet -q flags. The debug information is sent to stderr while the state is sent to stdout for use in scripts.

The only limit to the number of these relays that can be plugged in and operated at once is the number of USB ports. Using neither the -d or -q flags just prints the state of the relays to stdout.

The path to a device can be used in lieu of the serial, this can be useful for devices with corrupted serials. Use the fictitious relay 0 to set the serial permanently. If you have duplicate serials, make sure only one is plugged in when you change it. Maximum of 5 character serial.

It is probably sensible to change one module at a time to avoid serial collisions. You may also use the device path to set the serial as above.

This also optionally includes a python extension.Quick Links.

Make sure to connect the power supply in correct polarity. The driver package can be downloaded from the product page. To install the driver, unzip the contents of the downloaded driver package to a folder.

X stands for the number of ADC input. The response will be a number that ranges from 0 — Please see examples below. Using the relay module with Teraterm is just as easy. Please follow the steps below. Teraterm is an open source software. Controlling the module using a custom program This relay module can be controlled using custom programs written in many languages. Almost any language can be used as long as it supports some sort of serial communication method.

Set port parameters. An inductive load is pretty much anything that has a coil and works based on magnetic principles like Motors, Solenoids and transformers. The capacitor should be rated enough to withstand the back emf that is generated by the motor.
