I was thinking about to build my first robot, the robot that would animate the LEDs, respond to the sensor(s) that I may be added later, or do something relate to LED that are installed on the mouth.
Image 2, is the 3D model of my robot head. An inspiration from Instructables' bot.
This is a challenge for me to built this project, a project that has a lot of things that I am about to do the first time.
This is the first time that I design a laser cut pieces, which I doubted if they are going to fit together?
This is the first time that I am using 40 LEDs in the same project.
This is the first time that I am using three TLC5940NT ICs at once.
The challenge is to put 40 LEDs, three TLC5940NT, good amount of wires to connect all LEDs to ICs into a 5x5.5x6cm. Acrylic box (Robot Head).
And here is how I did it.
Step 1: Parts and Tools
3 nos. 16-channels PWM chips, TLC5940NT
40 nos. 3mm
Arduino or Arduino compartible
hook up wires
Laser cut acrylic (or wood) robot head (attached eps file below)
Medium length jumper wires
Foam core art board
The tools that I used in this project are:
Solder iron and Solder station
Needle Nose Pliers
Coarse Needle Files
