ATTiny85 Programming Jig
Note: Different Board
I used the Arduino Feather 32u4 board so I had to use a different ISP programmer (the 32u4 one)
Error: Incorrect Device Signature
Experiencing errors setting the jig up initially with this wiring. Turned out to be caused by a missing SCK wire.
The error is not helpful or informative since it indicates there’s something wrong with the device signature and I spent a lot of time trying to debug this issue which turned out to be caused by a missing wire.
(Incorrect wiring might also cause this. So likely if the device signature is incorrect, it could be caused by incorrectly connected wires)
Fix: Add the missing SCK wire and ensure everything is wired correctly.
Creating a Capacitive Sensor
One thing that’s unusual with this setup which I’ll try to diagnose later is that the capacitive touch works
Possible Cause: could be that Im using a 1m Ohm resistor only with a 220 Ohm resistor for the led.
So I can use another human being as my capacitive touch sensor.
