The Teensy is a complete USB-based microcontroller development system, in a very small footprint, capable of implementing many types of projects. All programming is done via the USB port. You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino […]
Send & Receive Radio With A Single Chip
https://www.electronics-lab.com/send-receive-radio-single-chip/
Fitting transmit and receive capabilities of radio signals into one device may be impossible without using a significant filter, which is needed to isolate sent and received signals from each other. The major obstacle to achieve that is the weakness of the received signal compared with the much stronger transmitted signal. However, researchers from Cornell […]
Arduino Parking Assistant
https://www.electronics-lab.com/arduino-parking-assistant/
addictedToArduino @ instructables.com designed a Arduino based parking assistant. To appease my frustration I decided to design a device that would allow me to park in the exact spot every time. I love working with arduinos, leds, sensors, and nearly anything else electronic, so I knew from the start that it would probably end up […]
Raspberry Pi Security System
