Hi,
I'm trying to help mentor some gcse kids and several are doing electronics,
One wants to make a circuit for his project that automatically waters plants.
Now I know a little bit about electronics, but not loads....I know they can't use pic chips at the school (no facilities) and reckon that it'll be an astable circuit I guess with a 555 timer with a variable resistor and capacitor to 'sort out the timing' but presumably then it should go onto a solonoid/motor to open a valve for the water device.
Anyone got any ideas that could help.
SOrry if I shouldn't post this...as my name suggests I am new to all this.
Cheers
