Example Project Kits on CARPE — Columbus Arduino & Raspberry Pi Enthusiasts

Motion Show

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

A motion sensor triggers an RGB LED strip and plays sound through an I2S amplifier. It started life as a Halloween pumpkin, but the combination fits plenty of other builds: a doorway greeter, a display case, an alarm.

What it teaches
#

Sense, then react with light and sound: one input driving two different kinds of output.

Environment Station

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

Reads temperature, humidity, pressure and light, and publishes them so they can be charted on a dashboard.

What it teaches
#

Sense and publish: the simplest useful IoT pattern, and the quickest route to a first dashboard.

Button and Buzzer Pair

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

Two boards: press the button on one, and a buzzer and light go off on the other, across the room.

What it teaches
#

Two devices talking through a message broker, rather than wired together.

Sound Meter

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

An I2S microphone measures sound levels in the room, and the levels are charted over time.

What it teaches
#

Streaming audio data, and turning a stream into something worth charting. It pairs well with the Motion Show’s I2S amplifier.

Shared Pixel Canvas

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

An LED matrix that anyone in the room can send pixels to, so the picture is a group effort.

What it teaches
#

Many publishers, one display: what happens when lots of senders share one device.

Camera with Object Detection

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

An ESP32 camera takes snapshots and detects what’s in them.

What it teaches
#

Working with images, and deciding where the heavy lifting runs: on the device, or on a bigger computer nearby.

Color Screen

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

A small color display that shows messages and status sent to it.

What it teaches
#

Driving a graphical display: layout, fonts and redrawing only what changed.

Serial Screen

Mon, 01 Jan 0001 00:00:00 +0000

Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.

What it does
#

A character display driven over a serial connection.

What it teaches
#

The simplest display there is, and a good first output device.

Parts (planned)
#

Serial character LCD
