This weekend I was going to play around with servos and motors, but due to a missing diode I only got the servo working, displayed below. Yes, that\u2019s a matchstick attached to it with Blu-Tac.<\/p>\n

<\/a><\/div>\n

The processing language is actually very nice to play with. If I squint and pretend it\u2019s Javascript then I can write in it without missing python too much.<\/p>\n

The whole purpose of playing around with electronics is deep down I\u2019d like to know a bit more about the factory floor hardware side of things. I\u2019ve written a lot of software for factories but hardware tends to be black box stuff. When I couldn\u2019t find the diode I needed I instead thought I\u2019d see if I could get somewhere with a\u00a0Direct ICS<\/a> plugged to an Arduino and SCADA<\/a>. Turns out you can. You need some modbus client code from here<\/a> and the Mango M2M system<\/a> from here.<\/p>\n

What was supposed to be hardware time ended up playing around a lot with Java, Tomcat and understanding what modbus is and does. But at the end of the evening (I packed it in early, I was whacked) I saw this on the Mango interface \u2026<\/p>\n

<\/a><\/div>\n

That \u20181\u2019, in the Nodes found list, is the sweet smell of success. Next step would be to fit some sensors on the Arduino and get Mango to monitor them.<\/p>\n
