Electronics

I have created two versions of this project, a simple one with movement and lights only and a more advanced version that uses a PIR sensor for motion activation and a feature to activate a speaker and/or additional devices.

The simple version is connected as follows…

The simple version can also be useful for diagnosis if you are having problems using the advanced circuit.

The advanced version is connected as follows…

Using a Custom PCB

The wiring can be simplified and compacted using a custom made PCB. They are available to purchase here. Funds from which will help support future projects like this one.

Follow the instructions below if using a custom PCB.

Position and solder components in the indicated locations and orientation
Solder male and female headers, you can solder the D1 mini directly to the board if you prefer
Trim any excess wire
Install the D1 mini and connect the servos, LED, speaker and PIR (if using), note the positions of the positive and negative pins using a multi-meter

Connecting the Speaker

Connecting the speaker very much depends on the type used, the voltage supply required etc. The doll I used is available to purchase here and contained its own speaker within the doll itself.

It was connected as follows…
