Here is a practical example of Arduino driving relay boards PoRelay8. PoRelay8 board with 8 relay outputs can be connected to any Arduino device if it can communicate via the I2C protocol. If 8 relay outputs do not satisfy your demands, additional up to 9 PoRelay8 boards can be daisy-chained over CAN bus, even with … Read more
Recently, one of our customers, Tomaž P., sent us a description of his project “Orchidarium automation”. He uses our PoKeys57U usb CNC controller as an automation control device. We are glad to hear our devices are not installed only in CNC control and flight simulator world but also used in such “green” projects as a … Read more
First part of this blog Raspberry Pi relay module PoRelay8 – Part1 was about connecting and controlling single PoRelay8 board with Raspberry Pi. Relay board and Raspberry Pi were communicating over I2C bus. Setup in this example has two limitations. First, I2C bus was developed for communication between devices on same PCB and can be … Read more
In this blog we will describe Raspberry Pi relay module example with PoRelay8. CAN relay board PoRelay8 features 8 relay outputs configured over I2C bus. Up to 10 boards can be daisy-chained over the CAN bus for up to 80 additional outputs. In previous blog (Using PoRelay8 with PoKeys and long cables) we wrote about … Read more
PoBlocks just got a set of new communication features in PoKeys57 series ethernet devices. UDP sender enables PoKeys device to send simple messages using UDP protocol on request from the PoBlocks project. PoKeys InterCom protocol on the other hand enables sending data between PoKeys devices. PoKeys (Simple) UDP sender As the name applies, UDP sender … Read more
In this PoBlocks tutorial, we will describe how PoBlocks can be used to solve a stepper motor positioning task. PoBlocks is a graphical programming tool for PoKeys device and is free of charge for PoKeys users. Background We have been approached by one of our users on how a positioning system can be implemented using … Read more
