The gating properties of the 4066 Quad Switch is the basis of this Noise Box which aims to produce a truly horrible sound/noise that is amplified by an LM324 Quad op-amp.
The project illustrates how to interface Atmel AVR with Graphics LCD which features a C library for AVR-GCC/AVR-LIBC to access SED 1520-based graphics LCDs.
The project illustrates the implementation of Numeric Simon Memory Game using the Olimex PIC-MT Dev Board which is suitable for 28-pin PIC microcontrollers.
The project uses two Microchip PIC microcontrollers to build this imaging sonar where a 16F84 is used for the servo control and a 16C71 for the sonar portion.
