A reader alerted me to the Tone function for Arduino. When I was making my WordPress hit counter I wanted to add in an audio alert. I preferred something other than a constant tone but thought I would have a go using the tone function. It turns out that the tone function is not implemented... Continue Reading →

I remember seeing an ESP8266 project years ago that displayed a Youtubers subscriber count on an LED display. I was really impressed by that project. Recently I wondered if a similar thing could be done with wordpress.com stats, in this case not showing subscribers, but daily views. I did come across this response to a... Continue Reading →
Batch processing files with Audacity
In my last post Using Text to Speech online tools to create audio files for Arduino projects I had some info about online text to audio sites I have been using to create audio alert files for projects. The files produced by ttsmp3.com seemed to have a lower audio level than I expected. I found... Continue Reading →
Using Text to Speech online tools to create audio files for Arduino projects
I’ve made a couple of projects that play audio alerts using a dfplayer and MP3 files. One in a clock that plays announcements and the other a countdown timer. When I did those, I used onlinetonegenerator.com to convert text to speech. I liked the voices but it doesn’t have an option to save the audio... Continue Reading →
Reliably debouncing rotary encoders with Arduino and ESP32
I love those simple cheap rotary encoders as used in the KY-040 modules as a method of getting user input with Arduino and ESP32 projects. The issue of bounce with them is significant and for years I’ve been looking a reliable method of dealing with it. I thought I had it figured out by either... Continue Reading →

Getting decent quality prototype breadboards for a reasonable cost is something that has eluded me for years. I think I have finally found a reliable source. Those advertised on eBay or at least the cheaper ones seem that I have previously purchased too often have poor metal connectors inside. It can be difficult to insert... Continue Reading →
