Mini T3.2 - Miniaturization of Teensy 3.2 board
FRDM4236 Nov 15,2021
Teensy 3.2 is a great microcontroller board and it's one of the most popular development boards in the Arduino world. Inspired by a user's project on the PJRC forum, https://forum.pjrc.com/threads/33347-Tiniest-Teensy, I have made the Teensy 3.2 board smaller. The Mini T3.2 board is a small Teensy 3.2 compatible board and is based on the same MK20DX256VLH7 microcontroller as the Teensy 3.2 is. It will work with Teensyduino as a regular Teensy 3.2.Note: The Mini T3.2 board includes a built-i...

Halloween Pumpkin with Sound and Light Effects
KILIC Oct 30,2021
Halloween is close and I wanted to make a related cool project. Of course, it will involve a pumpkin. Also I wanted to add some electronics, of course.For that, inside we have an Arduino connected to a few other parts. For light effects, I’m using an addressable controlled LED strip. For sound we have a mp3 module and to detect movement a PIR sensor. The scary pumpkin will stay powered off till it detects movement. Once it detects that somebody is close, it will run a few random loops such and p...
