In order to build the Elisa-3 firmware with the Arduino IDE 1.x the following steps has to be performed:<br/>
	*1. download the [https://arduino.cc/hu/Main/Software Arduino IDE 1.x] (the last known working version is 1.8.9, refer to [https://www.arduino.cc/en/Main/OldSoftwareReleases#previous Arduino Software]) and extract it, let say in a folder named <code>arduino-1.x</code><br/>		*1. download the [https://arduino.cc/hu/Main/Software Arduino IDE 1.x] (the last known working version is 1.8.9, refer to [https://www.arduino.cc/en/Main/OldSoftwareReleases#previous Arduino Software]) and extract it, let say in a folder named <code>arduino-1.x</code><br/>
	*2. download the [https://projects.gctronic.com/elisa3/~~elisa3_arduino_library_04~~.09.~~23_9c522de~~.zip Elisa-3 Arduino library] and extract it within the libraries folder of the Arduino IDE, in this case <code>arduino-1.x\libraries</code> (see [https://support.arduino.cc/hc/en-us/articles/4415103213714-Find-sketches-libraries-board-cores-and-other-files-on-your-computer Find-sketches-libraries-board-cores-and-other-files-on-your-computer] for more information on Arduino useful paths); you should end up with a <code>Elisa3</code> folder within the libraries. If you start the Arduino IDE now you can see that the <code>Elisa-3</code> library is available in the menu <code>Sketch=>Import Library...</code> (or <code>Sketch=>Include Lirary</code> in later IDE versions).<br/> In later versions of Arduino IDE you can also install the library via menu: <code>Sketch=>Include Library=>Add .ZIP library</code>, for more info have a look at [https://docs.arduino.cc/software/ide-v1/tutorials/installing-libraries#importing-a-zip-library importing-a-zip-library].		*2. download the [https://projects.gctronic.com/elisa3/elisa3_arduino_library_03.02.25_65964ed.zip Elisa-3 Arduino library] and extract it within the libraries folder of the Arduino IDE, in this case <code>arduino-1.x\libraries</code> (see [https://support.arduino.cc/hc/en-us/articles/4415103213714-Find-sketches-libraries-board-cores-and-other-files-on-your-computer Find-sketches-libraries-board-cores-and-other-files-on-your-computer] for more information on Arduino useful paths); you should end up with a <code>Elisa3</code> folder within the libraries.
