Arduino Recreation

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.

A video of the working circuit can be seen below in Figure 1.

The nRF modules were then wired to two seperate arduinos. The receiver uno (wired to joystick) was then wired to power the sender uno so that the usb could power both.

The sender and receiver module were then wired to send a string to test rf communication with the code images in the images file.

The joystick signal was then sent over rf to the motor. The connection was unstable on campus even though the connection was stable at my house making the motor control difficult but it worked momentarily as seen below in Figure 2.
