Project Description

Hi All,

I'm building a unit with two buttons on it.

For this bid I need an internal circuit boardlogic designed. The unit have two buttons and a few leds (optional) and a GSM transmitter.

The number of times each button was pushed is being counted and accumulated and once an hour all this information is being sent to a centralized server in the internet (the API for the server is ready). The leds will indicate the box status - errors, battery running out, etc.

The size of the box should be about 100mm X 100mm X 20mm and the batteries should last a couple of months at least (optional - solar panel can charge batteries during standby).

Unit spec is attached.

Thanks!
