Uses MOSFETs to intialize power and maintain power by HIGH output on PD7. Initiated by trigger-switch momentary closing.
Circut includes NRF2401 to transmit trigger event and battery status to listening unit.
Self power-down with PD7 LOW.

This is an arduino nano based soldering station. **Tested, working version.**
-Designed to work with rotary encoders.
-Built in Beeper.
-Built in memory buttons to store often used temperature values.
-Built in Debounceing for the buttons. (up to 7 buttons, built in 3 buttons)
-Designed to work with a MAX6675 module for temperature readings from a K-type thermocouple.
-Built in LCD head...
A dual microcontroller board for controlling "Neopixel" LEDs, with one micro dedicated to driving the LEDs while the other micro is busy reading push buttons, polling rotary encoders, reading IR remote signals etc etc.
The microcontrollers -two atmega328s -communicate with one another over their I2C bus. The very short wire run negates the need for the usual pull up resistors on the bus.
This is not in any way my design or idea. It's based on the work of Daniel Perez over at https://generatorlabs.wixsite.com.
I just converted the pdfs of the schematics and made some small improvements for easier connectivity, to allow anyone who want to build it theirself.
I thank him so much for sharing this awesome project along with the arduino code. Please check out his 3 part video demostra...
EasyEDA project for simple and quick assembly of the "SWR-mouse" antenna analyzer adapted for installation in the [G403 case (Gainta Industries)]. The project includes the "SWR-mouse" antenna analyzer schematic and the PCB file. Version for mounting SMD components.
## Current development progress:
To test the series of sensors contained in the package "37 in 1 Sensor Module Board Set" which is sold by many sites it is possible to use this shield compatible with Arduino UNO original R3 and related clones.
On the board are available many connectors that are already properly connected with the digital or analog ports of Arduino.
In fact, the card, in addition to the sensors in the "37 in 1 Sen...
