I. Overview

in this week we have to

• use the test equipment in your lab to observe the operation of a microcontroller circuit board.
• redraw an echo hello-world board, make it, and test it

Using test equipment

Here I show you, how I measure a PWM signal with a Multimeter and Oscilloscope

Redraw an echo hello-world board

Here is my walkthrough drawing schematics and making the board in Eagle

Making the board

Here are some pictures of the making process

Flashing the Bootloader

Here I describe how to setup the ArduinoIDE to work with ATTinys and how to flash the bootloader to them
