Here is the circuit of an Arduino-based Panic Alarm! The wiring is very simple so that even a novice can construct this interesting circuit without any difficulty. Arduino is a family of ...

An Arduino is a much better choice than a Raspberry Pi for tasks that require real-time input and responses. While a Pi can ...

Next is the complete schematic diagram of a little Arduino board for your everyday projects. Use the Atmega328P chip, with Arduino bootloader loaded by you, as the brain of this economical circuit.

The project itself simply says the vague shape is what ties it to Arduino, and reads a bit like an advert for a PCB fab. I’d prefer those big clunky PIC devboards with this 8051.
