Assignment 1: Bootloading Jig

Assignment 1: Bootloader Jig

The Idea

The project consists of developing a shield for an Arduino UNO which makes bootloading brand new microcontrollers easily.  In this specific case I will be flashing an ATTiny85 microcontroller. To make this procedure I followed Andrew Sigler’s Programming an ATTiny85 Guide.

The Result

Bill of Materials

– 1 Arduino Uno
– 1 ATTiny85 microcontroller
– 1 470 uF Capacitor
– 1 0.1 uF Capacitor
– 1 PCB Board of choice
– 1 LED
– 40 cms 22auw wire

Process

Mainly, the process consists of flashing the code onto the ATTiny85 microcontroller using an Arduino Nano.

Setup: Arduino UNO connected to ATtiny.
Setup: Arduino UNO connected to ATtiny.

Following the guide, now that I could see the LED blinking it meant the code was uploaded!

After checking the whole circuit worked on the breadboard, I soldered the whole setup onto the PCB board.

Finally, after a bit of flux and a couple of minutes of soldering, I made the Jig!
