rotary-turbo-PCA9685
Led dimming code for rotary encoder with turbo
...Turbo mode start if turning rapidly rotary weel and stop automatically after 3 seconds. Tested with stm32f103c8t6 (blue-pill) and PCA9685. For used scale I added gnumeric spreadsheet for double type value control match with integers in arduino schetch. You can modify this code according yours own needs. Pls consider this: a - using for led dimming: with logarithmic derived scale consider apparent light intensity modulation not of light source but for whole light reflecting 3d area; with scale range (here 500 steps) and timing for turbo mode, you can adapt this code with whole 3d area regarding light reflecting caracteristics and rotary using mode also reducing 360° rotary turns number not needing very large single step luminosity difference; b - with motors, ... be careful using turbo. :-) -

ICARU_FB is a small RTE (Run Time Environment) for IEC 61499 standard. It can run on Arduino performing all the IEC 61499 standard requirements as configurability, portability and interoperability. Check our paper: https://ieeexplore.ieee.org/document/7445830/ ICARU_FB is in a initial stage. So, it needs many improvements in code, documentation, and others. But, due to the ICARU_FB code simplicity, at least now, code change is easy in a way and can be a basis.

IRremoteESP8266
Infrared remote library for ESP8266/ESP32
Infrared remote library for ESP8266/ESP32. Send and receive infrared signals with multiple protocols. This library enables you to send and receive infra-red signals on an ESP8266 or an ESP32 using the Arduino framework using common 940nm IR LEDs and common IR receiver modules. e.g. TSOP{17,22,24,36,38,44,48} demodulators etc. Usage of the library has been slightly changed in v2.0. You will need to change your usage to work with v2.0 and beyond. You can read more about the changes required on our Upgrade to v2.0 page. The library has changed from using constants declared as #define to const with the appropriate naming per the C++ style guide. ... -

PU2CLR SI4735 Arduino Library
This document is aimed at the Arduino developers, radio experimenters
...This library also has primitive functions that make it easier for you to implement commands that may not have been implemented yet. See setProperty, getProperty sendCommand, getCommandResponse and getStatusResponse functions and also How to customize PU2CLR Arduino Library. It is worth noting, however, that this library is constantly improving. Check the API documentation before implementing a new function. It is likely that your demand is already implemented. See the API documentation for this library. -

NMEA_ZDA_TO_UTC
Insertion message $UTC et correction temps réel décalage PPS
NMEA_ZDA_TO_UTC Insertion du message $UTC avec correction en temps réel du décalage avec le signal PPS. Permet de bien faire fonctionner certains équipements qui demande le message $UTC d'Applanix, mais en utilisant un GPS générique. Le point décimal de l'heure UTC compensée dans le message $UTC est synchro à ± 0,5 mS avec l'heure réelle UTC. Vous pouvez donc vous servir de ce repère comme d'un émulateur du signal PPS bon marché. Ce n'est pas un signal au TOP de la seconde (!... -

nano_voltmeter
Nano voltmeter based on the Arduino Nano
...All signal processing after the chopper is done in the AC domain with the circuit configured as a nulling amplifier. AC amplifier gain is 10,000,000 and the amplifier is fed into the Arduino ADC. This gives resolution of 100 pV per bit with higher resolution possible because of averaging. A 16 bit PWM followed by a passive five pole RC filter is used as feedback to the chopper creating a null meter. Because of this feedback, the effective input impedance approaches infinity and gain errors are eliminated. A commodity CMOS op-amp and no precision parts are required to get five digit precision. -

MFJ-993b Web Remote
Arduino Mega 2560 + Ethernet Shield to Drive 8 Relays for MFJ-993b
Arduino Mega 2560 Code to that supports a standard Ethernet Shield . i.e. Drive Relays hence outputs to MFJ-993b. Supports Up and Down for manual L and C Tuning, Autotune On/Off, Antenna Selection 1/2 and 100ms Short /1000ms Long for Tune. Op Note 1: You may need additional power for the 5V relay board; sometimes you can power the 5V relay board from the Mega 2560 - but reset/start the device first and then connect power to the relay board.
