Hello world! Last month, we connected our homebuilt PICAXE 08M2+ breadboard to
some simple robotics hardware and started programming. We blinked an LED and
got a servo moving under IR remote control. Part 1 was about making the
breadboard and USB adapter, and getting connected to a PC using the
Programming Editor (PE). Programs are written in PICAXE BASIC, then downloaded
to the 08M2+ (in other words, programming the 08M2+) through the USB adapter
and a three-pin breadboard connection. That same USB connection lets the PICAXE
send data to the PC screen using the serial terminal (F8), which is very useful for
monitoring PICAXE input and output values, calibrating sensors, and general
debugging of a program. This month, we'll look at some simple sensors to give our
breadboard the ability to measure distance, light, and temperature. Finally, we'll
make our breadboard into a simple robot!
