BMP280 barometric pressure and temperature sensor. Wraps https://github.com/adafruit/Adafruit_BME280_Library. Datasheet: https://cdn-learn.adafruit.com/assets/assets/000/115/588/original/bst-bme280-ds002.pdf. N.B. UNTESTED!

Generates rectangular waveforms of a user-defined duty and period. Waveforms can have a maximum frequency of 1MHz (period of 1 microsecond). Uses Paul Stoffregen's TimeOne library: https://github.com/PaulStoffregen/TimerOne.

Copy of std Ultrasonic range, but returns Max distance on failure so we can assume nothing close to us. My sensor seems to go low on ping capture, not success, so I changed timeout to max round trip to get full range.

Controller for the webasto thermotop C diesel coolant heater ECU (also applicable to the chinese knock offs) , a modified version of the Webastardo board originally designed by Simon Raffrey that runs on arduino IDE written code. It handles the various procedures for starting up, pid combustion manager to reach and maintain a set coolant temperature and shutting down sequence, as well as various safety, alarms, standby, information display and input via rotary encoder. At the moment is missing BLE functionality to use a phone app to control it remotely.

A non-volatile integer counter with a calculation result from 0.00 to 4294967000.00. The result of the calculations is converted into a 32-bit unsigned integer, represented as four bytes. The result of the calculations is recorded in the eeprom by a signal from the voltage monitoring port. After resuming the voltage on the chip, the eeprom is read first, followed by further calculations. The resulting number can be further used in subsequent calculations or displayed on the LCD.

Extension pack for Amperka Colony

It became necessary to create a filament counter for your 3d printer. During the writing of the program, I created a new multiplication node. I used the hall sensor and the ssd1306 LED display on the i2c bus .
