From your downloads, open the example labeled as Example1-ReadButtons_WriteLEDs.ino.This example reads a switch and writes to the non-addressable LED using the PCA9554 I/O I 2 C Expander.. For users ...

All of these examples will run on an Arduino UNO. I have in fact used a NANO and a backplane which has more ground pins available. There is a need for a TCRT5000 IR detector and a servo and connecting ...

With Arduino C, small if/then state-machines generally come out smaller a switch/case version. Which ever is chosen, the result is pretty efficient, and the switch/case penalty is rarely greater than ...

Code explanation. The complete code for this Arduino reed switch project is given at the end of this article. The code is split into small meaningful chunks and explained below. In this part of the ...

Relay: Relay is an electromagnetic switch, which is controlled by small current, and used to switch ON and OFF relatively much larger current.Means by applying small current we can switch ON the relay ...

This archive contains a code library and application programming interface (API) for controlling the InnoSwitch3-Pro IC using an Arduino microcontroller. It includes C++ and header files to support ...

[Jean-Noel] is fixing a broken Lurem woodworking machine. This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a… ...
