Description: Output at pin 3 should fire once every 0.4 seconds. This should trigger Q1 and activate the solenoid which sprays water mist to a unborn plant mushroom seedling (inside a wooden log) at 2 time a second. To reset, push both buttons at the same time. The buttons have been corrected. Haven't put to real life test or run on a computer simulator.
