The TomatoCube IR & Magnet Polarity Tester is a handheld test tool built around Microchip's ATtiny1614 microcontroller with a 16x2 HD44780 LCD. Point an infrared remote at its IR sensor and any received IR datagram is shown on screen; press the button for secondary details on the received datagram. Bring a magnet near the Hall effect sensor and the tester displays which pole, North or South, is facing it. The firmware is built in Arduino using megaTinyCore.
