Teensy 4.1 Featured in 10 Best Microcontrollers Article
The PJRC Teensy 4.1 (and a couple of other microcontrollers we carry) is featured in EE Times' article on the 10 best microcontrollers on the market. https://www.eetimes.com/10-best-microcontrollers-on-the-market/
Introducing the Teensy 4.1 Microcontroller Development Board
The Teensy 4.1 from PJRC is now in stock and ready to ship from Envistia Mall. Teensy 4.1 features an ARM Cortex-M7 processor at 600 MHz. Actual size is 2.4 by 0.7 inch, same form-factor as Teensy 3.6. It uses the same processor as Teensy 4.0, but provides greater I/O capability, including an ethernet PHY, SD card socket, and USB host port. Teensy 4.1 also comes with 4X larger flash memory, and has 2 locations to optionally add more memory. Not every project requires so much I/O or extra memory. Teensy 4.0 fills those needs. But when you do need more I/O,...

Build a People Counter Using an ESP8266, NodeMCU and HC-SR501 PIR Motion Detector
Want to get an idea of how many people are coming and going in an area? Build your own people counter with an ESP8266 NODEMCU, HC-SR501 PIR Motion Sensor, Ubidots Cloud, and the Arduino IDE. A people counter is a device that used to measure the number of people traversing an entrance, hallway, street corner, etc. If you need to know how many people exist in a space, this is your simple solution. Mostly used in retail stores, shopping malls, and smart office buildings, this counting technology has provided insight to how shoppers/employers behave.How is the people counter application applicable...
Make Your Own Arduino Header Pins
If you've ever made a custom Arduino shield using standard perfboard, you know the two digital IO headers are separated by a non-standard distance and won't line up.Rssalnero on Thingiverse tried using needle nose pliers to bend the pins to match and failed miserably. So he created two simple 3D printed jigs that let you bend an 8-pin header. The first jig bends the correct offset and the second helps you straighten out the ends again. You can see the result in the picture above.t's a pair of jigs for bending an 8 pin header the precise amount needed to...
