The Skull is a Capture the Flag (CTF) puzzle that invites you to explore the innards of the AVR architecture. It has multiple stages that may keep you busy for days or even weeks as you flex your brain muscles and apply them to her riddles. Unless, of course, your mind loses its grip on reality and you fall into a swirling void of madness with no anchor. In this case, it may take you longer. To keep your head above water, you need three things: the ability to read and understand Arduino code, a willingness to spend some time reading the ATtiny45 datasheet, and basic programming skills.
AquaPing is an ultra-low power smart sensor that provides isolated water leak detection, even behind walls.
This project uses the 430 series MSP430F5310 microcontroller as the central processing unit to develop a new type of fault indicator to indicate phase-to-phase short circuit faults and single-phase ground faults that occur on transmission and distribution lines of 10KV and below. Its main working process is: sensing real-time voltage and current values from the high-voltage line, and sending them to the microcontroller for analysis and calculation after hardware processing. If the fault conditions are met, a flop signal is sent to cause the indicator to flop, and the action information is transmitted wirelessly. The communication module transmits the information to nearby communication substations.
Do you need a small ISP to program your onboard AVR device? POGO ISP Micro is the right solution!
Wireless Communication with NRF24 and Arduino Pro Micro
The RoverWing is an expansion board (or "wing", following Adafruit's terminology) for the Adafruit Feather board that provides motor drivers that can handle 6-12 V motors, an inertial motion unit (IMU), and common servos, acoustics, etc. for mobile robots. Connectivity ports for GPS, GPS and other peripherals. Affordable, with powerful Arduino libraries and excellent documentation. It also contains a microcontroller with preloaded firmware to control these peripherals, which communicates with the Feather board using the I²C protocol, thereby freeing up the Feather board's resources for other uses.
The Speeduino project is a flexible, fully-featured engine management system (EMS aka ECU) based on the low-cost open-source Arduino platform. It provides the hardware, firmware, and software components that make up an engine management system, all under an open license. With over 1,000 installations, Speeduino has evolved into a product that meets the needs of the hobbyist and enthusiast community without the price tag of a traditional aftermarket ECU.
