Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

RA2L2 low-power MCUs are the industry’s first MCU to support USB-C Revision 2.4 with 15W CC detection, USB FS, CAN, I3C, and low-power UART.

If you had a calculator in the 1970s it probably had one, but in the present, [Joshua Coleman] has incorporated one into a pleasingly retro digital clock ... simple circuit, and the code is ...

Abstract: A 1.58 pJ/b 9 Gbps half-rate reference-less clock and data recovery (CDR) circuit with a sigma range detector (SRD) is presented. The SRD detects the ...

Abstract: This paper introduces novel ultra freezing attacks on clock oscillator circuits. The new attacks leverage liquid nitrogen to rapidly freeze quartz crystal oscillators and MEMS-based ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

Uses an ESP8266 module and an Arduino sketch to display the local time on a inexpensive analog quartz clock.
