The board layout and the source code is all available on GitHub. Because the switches are analog, they are bidirectional. That is, it isn’t really connecting one output to 32 inputs.

Thermometer – mercury height rises as temperature rises Car Speedometer – Needle moves farther right as you accelerate Stereo – Volume increases as you turn the knob Reason for conversion of analog to ...

Analog signals – directly measurable quantities in terms of some other quantity. Examples: 1. Thermometer – mercury height rises as temperature rises 2. Car Speedometer – Needle moves farther right as ...

The build relies on that old stalwart, the Arduino Uno, to run the show. It’s hooked up to a DS3231 real-time clock module so it can keep accurate time for long periods, as is befitting a clock.

In comparison, the Arduino Uno, Leonardo, and Mega 2560 boards all have theoretical ADC speeds of 15 ksps. Caption Dual USB inputs and 12-bit analog I/Os.
