Story

DIY electronics project for kids. Using obniz, your smartphone's accelerometer, a speaker, and a servo motor, the bird sings and moves when you move your phone.

Step 1: Setting Up obniz

To set up obniz, all you need to do is to follow three steps.

Connect obniz to WiFi.

Connect devices like LED or motors to obniz.

Scan QR code of obniz and start programming. You do not need to install any software.

Step 2: Making the Bird

First, you need to create the base as below. Cut paper into circle shape and make a small hole in the circle for the servo motor.

By using double sided tape, attach the circle to the servo motor.

Create your bird with paper cup and put the bird on the servo motor.

Fix the paper cup and the servo motor as below.

Step 3: Connect Wires to obniz

Piezo speaker: io0 and io4

Servo motor: signal to io9, vcc to io10, and gnd to io11

Step 4: Program

Write the code on the program section and open HTML.

You are ready to use it! Tilt your smartphone to let birds to sing and move!

What Is obniz?

obniz is a cloud-connected IoT development board. You can program on the web browser of anysmartphone or computer and the command is sent to obniz through the internet via obniz cloud. By connecting the obniz to the cloud through WiFi, users can remotely control devices that are physically connected to obniz.

obniz has 12 IO and WiFi-BLE module. It can be controlled through the APIs – REST or WebSocket API – on obniz cloud. Not only simple IO on/off but also UART, I2C, BLE etc can be used by remotely controlling obniz via internet. All you need to do to connect obniz Is to input unique ID by scanning QR code. Complicated processes are done by obniz and its cloud. You can just start programming in HTML, browser and circuit have already been integrated. If you write a program to collect sensor values, you can make a chart of the values easily.

In terms of hardware, every IO can drive up to 1A with overcorrect protection, therefore high current demanding devices such as motors can be directly connected to obniz IO. GPIO and AD can be used on every IO. UART, SPI etc peripherals can be assigned to every IO.Even output voltage 3v/5v can be changed by software. Most electrical parts can be connected directly. Embedded parts such as switch, OLED display, and BLE are ready for use on program.

  } else {
    speaker.stop();
