Introduction:
This is the process of me reverse engineering the Burner Alert system.
A small PCB designed to mount onto stove knobs and buzz every so often
when the burner is on. In part 1 I am using an arduino uno, arduino
buzzer, and an MPU6050 to understand the logic of the circuit before
recreating it with other components.
Materials:
Stepper Motor, 2x Uno, 2x nRF24, Joystick
Methods:
One joystick was wired to the sender arduino analog input.
The PCB I received had placed the pads on the wrong side of the PCB
making it dificult to solder. I made sure this wasn't my fault by
checking my EAGLE and putting my gerber files into a GERBER viewer.
Both of these displayed the pads on the top layer of the PCB, the same
side as the silk screen. I tried to solder the board anyways bending
the voltage regulator pins so that it could be soldered upside down.
The oscilator however had shorted all three pads together for some
reason making me unable to solder the oscilator. I tried to cut the
connection between these pads and solder a resonator between the pins
buty even after this I was unable to load code to the ATMEGA chip. I
think this is due to some part of the resonator but I was unable to fix
the issue. The PCB can be seen below.
