I am working on a project with my son. We need to build a small circuit powered by a 9v battery, which is activated by a push button on/off switch. The objective is to run a small (.13 amp) fan for 2-3 minutes. The fan will need to turn off automatically.
I have limited knowledge, so please forgive my amateurism. I understand that I may need a 555 chip and a potentiometer to have the time adjustment. I need to know the values for each resistor, capacitors and diodes necessary. I believe that I may also need a relay, I prefer a small 5v if possible due to the lack of space.
Most importantly, I will need to have step by step wiring instructions, as I can't read a schematic. If I can view a strip boad diagram from both the top and bottom, I ca wire, solder and reconstruct from there. Thanks for helping a dad in need.
