The folks at Dexter Industries don’t seem to need any sleep, it seems.  They’ve published a new set of program samples that allow you to communicate with your robot over WiFi through WebSocket using the dWiFi sensor.  What is WebSocket, I hear you ask? According to Wiki: WebSocket is a web technology providing for bi-directional, full-duplex communications channels over a ... Read More »
