Good Day everyone.
I got all the tools I need to do my project except the programming know how, I did write a few basic programs to test the different functions I want to perform and it all works great, ARDUINO RULES!.... But I don't know how to incorperate it all into one smooth running program so that I can prototype it. Basically the inputs are a copper probe in water ( I just used a 1M pull up resistor to detect when probe is no longer touching water) and a LM35.
Outputs are 2 leds, (or one red and green) 1 pmw transistor outpot and ine digital transistor output.
Here's what I want it to do. Monitor water level and temp, if water level is fine and temp is under 100c then green led on... All other outputs off
If water temp rises above 100c switch pwm transistor , step 51 for ever 2c above 100c and 110c...... (5 speed cooling fan).
If water temp exceeds 110c, light red led, count 10 second then turn on digital transistor output (cuts the system)
All the while I need a clock to count running hours (service light) once it has run for 100 hours make green led flash) there must be a way to reset this "service light".........
I would like to add an optional lcd display at a later stage, but that is not necessary at this stage......
Anybody interested in getting involved please let me know,
I would like to add an lcd display at a later stage and add one or two more
