I own a Huawei P20 phone with the Leica camera. I try to take at least 1 half decent photo every day if I can.

In 2020, Apress published my 1st book, 'Arduino Software Internals'. My 2nd, 'Arduino Interrupts', was published in 2023. I'm now writing a 3rd plus a 2nd edition of 'Internals'.

Currently living in Yorkshire, UK.

No longer on Twitter as .

Arduino Interrupts - December 2023.
Arduino Software Internals, Second Edition - coming later in 2024.
