Assignment; measure something: add a sensor to a microcontroller board that you have designed and read it.

For this assignment I decide to make a circuit based off Neil's hellobuttorn board here. So using the cicuit as a reference, I designed mine based on the ATtiny45. The design was done in Eagle.

Schematic design...

I then routed the pcb...

I then exported an image and made the circuit.

While checking for connection errors using a digitalmultimeter, I encountered multiple errors which I realise arose when solder flowed over to other lines. So I went back to the board and removed the ground plane.

Assignment wise:
