A weblog focused on interesting circuits, ideas, schematics and other information about microelectronics and microcontrollers.
Programmable BASIC controller
Tiny Basic Controller (TBC) is a simple device that can operate as a PLC (program logic controller) for home automation, control, etc. The control program is a text version of BASIC language.

I love these simple machines with high-level language (ahhhh) embedded. This is an example of such devices: One ATMega8, some bijou around (MAX232, power management), many I/O lines and programmable through a serial line (with Hyperterminal, e.g.) The main task of the controller is to interpret BASIC commands.
The TBC version of the BASIC language has commands to operate with discrete I/O, ADC and PWM.
