I had a couple of accidents where they magic smoke was released from a couple of Arduino boards when an Arduino module was bumped and moved over a... Continue Reading →
I love the DS3231 RTC module and have used it in a couple of projects without a library using code based on Ralph Bacon’s example. It worked well, but I wanted to use the alarm and working out how to do that was a step too far for me. There doesn’t seem to be a... Continue Reading →
When I was working on the Morse Code Decoder project I got unexpected results from the output of of the KY-037 audio module. The output was being monitored by an interrupt in the Arduino Nano. It was triggering far more than I expected. I wondered if it was triggering at the frequency of the audio... Continue Reading →
Decoding recreated Morse code from the Titanic I find the history of Morse code fascinating. I admire those that are able to send and interpret Morse code messages at high speed. Some time ago I saw a YouTube video about a Morse Code decoder that was based on a micro controller. I didn’t see the... Continue Reading →
