Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

Most current microcontrollers offer I/O ports that can change their functions during program execution. As outputs, the circuits can sink and source reasonably large amounts of current. This Design ...

Atmel has introduced a 6-pin microcontroller. The 8bit AVR ATtiny10 has 1kbyte of flash and 32byte of SRAM in a 2x3mm SOT-23 package. Performance is claimed to be up to 12MIPS, and peripherals include ...

Although the CRT has largely disappeared from our everyday lives, there was a decades-long timeframe when this was ...
