Hello! 👋

This program can be used to visualize incoming accelerometer and gyroscope data from an MPU-6050. It does this by using an ESP32 to host a web server. The server exhibits a prism whose 3D rotation is based on the orientation of the accelerometer. This program was originally made using Visual Studio Code and the extension PlatformIO. However, it still uses the Arduino framework, so if needed the Arduino IDE can be used*....

This program can be used to see TCP, UDP, ICMP, and other incoming packets to an ESP32 board that is connected to a WiFi network. A different color LED is also turned on when different protocol packets are received (red for ICMP, green for TCP, blue for UDP, and yellow for others). It also outputs the source IP address of each packet. This program uses Visual Studio Code and two extensions: ESP-IDF (Espressif IoT Development Framework) and PlatformIO....

This box can be used to verify that an OBDII device can both send and recieve CAN data frames. It does this using a CAN bus module that allows the Arduino Uno to communicate with the device over the CAN High/Low pins of the OBD port. Materials Arduino Uno R3 MCP2515 CAN Bus Module OBDII Female Port Power Supplies Jumper Wires Wiring Also note that, when not being programmed, the Uno is powered with an external 9V 3A power supply....

This program lets the user know when a washing machine cycle finished and when the door was opened. It does this using a microphone sensor to listen for the dinging noise at the end of a cycle as well as a humidity sensor to measure when the humidity spikes indicating that steam/vapor is coming out of a freshly opened washing machine. It can also predict the time that a cycle will finish based on the manufacturer cycle time for different modes (delicate, normal, heavy, etc....
