This is my IPC final! It is a drum machine with an 8 steps step sequencer and 4 tracks. The step sequencer uses buttons with LED lightning to tell which step is currently active and which step is currently the playhead is on. The Mighty RP2040 For the main controller I opted for an Adafruit…

This is less than a final “planning” more like an update. I finished the entire controlling software on my RP2040 Metro. I tried the AdaFruit M7 Metro with IMXRT1011 but the RAM is not large enough (128KB vs RP2040’s 264KB). Currently the controller can do the following things: However I want some extra features like:

We decided to make a drum machine with a step sequencer and replaceable drum audios. Each drum machine will contains 4 audio modules called “Element”. Each of them is a fully self contained sound chip with audio playback capability. Techs will be used in this project: I also got the step sequencer’s demo working. In…

It’s almost final! Which means it’s time to plan about my final project. We learned about serial communication last week and did some experiments on it. This weekend I experimented with some I2C and SPI on my cheap little microcontroller. I have to say it’s not easy. It does not have Wire.h like Arduino and…

This is our midterm project! It’s a Halloween themed candy bucket with light and sound effects. When activated from the ultrasound distance sensor inside the pumpkin candy bucket it will move a paper cut-out of a ghost while also saying “don’t touch my candy”. This project uses an Arduino 33 IoT (ARM Cortex-M0+) as the…

After a group meeting we decided to combine our idea to create a candy basket with ghost shadow effects and sound. This is a list of material we will need: When the distance detected by the ultrasound distance sensor becomes low enough the master controller will move the servo which have a ghost cut-out on…

My plan for my midtern is now decided. The plan for my midterm will be “A candy bucket that plays a noise and blinks a few lights when the distance sensor is being activated” I recieved my PY32 chips and after some prototypes on my breadboard I whipped a PCB for my sound module and…

The theme of this midterm is Halloween themed and I am here to plan about what will I do in this midterm. Til this point we have learned these knowledges: I am not sure if I want to use devices that uses items beyond these key points but probably not. This is a teamwork project…
