ADC (Analog to digital converter) is a commonly used peripheral. We use it everyday to interface with several analog sensors. Many times a nice visualization of ADC data is required during learning about new sensors. For example you just bought a analog sound sensor, and try to do some fast experiments that how it performs.

This Speaking Calculator project is an interesting device built just by three chips that can be very useful to blind people. The system has four basic operations (addition, subtraction, multiplication and division), and the functions: clear all, change of sign (+/-), inverse (1/x), square root (v), pi number (p), add with memory (M+) and read
