Inputting multiple bits of information using a single entry pin of a microcontroller without the complexity of UARTs can prove useful. Such a scheme could allow scanning of a keyboard, mode switches, ...

Pin 8 (GND) and Pin 22 (AGND) have both been connected to ground. The final step is to connect the LED to output 0 on Port D. Our schematic tell us that we want to connect the positive lead of the LED ...

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 ...
