Hi Arduino forums,
I’m working on my own circuit board that I’ve programmed using a UNO.
The microcontroller is an ATtiny85.
I’ve programmed the ATtiny to run through several light functions at the push of a tact switch. Which works quite well on a breadboard.
However, after finishing building my circuit I’ve experienced trouble in the function. I would like the chip to transmit the signal of the button press through a micro usb port to a LED on the opposing end.
I imagine it has something to do with my traces.
PB1 of the tiny is the designated light variable, while PB0 is the button variable. I’ve attempted multiple arrangements of PB1’s trace. Initially I wired it directly to Vin expecting it to turn the light on on the other side of the usb. When this did not work I tried wiring it two GND. Still no such luck.
Attached is a schematic of the most recent board with PB1 wired to GND. IC1 is MIC5225 and IC2 is MCP7381. This board is an adaptation of the Trinket by Adafruit. I initially spoke to them regarding the problem but perhaps it is a conflict of interests. I do not intend to use this board as a programmable microcontroller.
I only intend to used the single LED code applied to it.
