Arduino irrigation control via time based on weather

Image
I would like to introduce you to the project that I realized during this year during the holidays. I created a web-based system for horticulture that specializes in the sale and cultivation of various kinds of plants, trees, flowers ... Web-based system has been designed to meet the following requirements: Temperature record, rain level, output activity record Heating / cooling control based on temperature Irrigation management at set times or on demand with weather condition counting statistics Remote restart boards Logs Login system Arduino Mega 2560 (1280 was enough too) was used as the control microcontroller, as Uno was on the edge with memory and was severely jammed. Arduino Mega was a great choice thanks to a sufficient number of pins and especially great memory for a program with a larger RAM memory. Arduino sends temperature and rain data to the Web via the Wiznet W5100 Ethernet Shield. The temperature is read out digitally from the DS18B20 sensor and the rain re

Firesport stopwatch via Arduino with LCD display

Today I will introduce you briefly the fire stubs, or the timekeepers I created it as huge firesport fan. The competition firefighters team is guessing every village or part of the city. Every week, especially in the summer season, competitions take place in the villages, and the teams attribute valuable points, successes and failures decided by hundreds or thousands of seconds. For this purpose, I have created simple stopwatches, which to a certain extent allowed me to measure time, for example, in the training of domestic firefighters. For the whole logic of the system, I used the millis, which is the function of the internal Arduin timer, which returns milliseconds from the start of the processor. So we can measure time to 3 decimal places (1000 ms = 1 second). We can therefore determine the accuracy of one thousandth (not real....). This means that we can measure time. We need some initial impulse - something we take down the start time and run the whole logic of the system.
