Design a cheap circuit - LED flash
€30-250 EUR
Paid on delivery
The purpose is to create a simple PCB with the following characteristics:
1. the used components should be very cheap;
2. the circuit should be powered by a small battery, with enough capacity to be used for at least 4-5 months under the conditions mentioned below;
2. the shape containing the PCB will be round, with a diameter of maximum 3 cm and as flat as possible (to be integrated in a plastic package together with the battery);
3. the function of the circuit is: a) after the power on, it flashes a LED for a period of 3 months; b) after the 3 months period, the circuit flashes another LED with a different color, for an additional period of 1 month; c) after the new period of 1 month, the circuit flashes a 3rd LED with a different color and keeps flashing the LED until a RESET button is pushed.
4. the duration of the period when LEDs are switched off to be calculated and mentioned considering the point 2.
The package containing the circuit will be similar with the attached picture.
The winner should provide:
-schematics,
-list of components and characteristics;
-PCB layout;
-5 sample circuits.
