MP3 speech files for use in clock projects

In recent post I’ve posted about Using Text to Speech online tools to create audio files for Arduino projects and Batch processing files with Audacity. I have a couple of projects that use speech alerts and one of those is a speaking clock. It announces the time at the press of a button, but more […]

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 […]

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 […]

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 […]

Finally, a decent quality prototype breadboard for a reasonable cost

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 […]

IR remote control mute button

I recently built a simple one button Arduino based IR remote control to mute our TV and Computer amp. I am quite happy with the results. The idea to use half a stress ball for the mute button I thought was inspired. The timber case built using with the aid of some jigs I made […]
