ZigerBot

Arduino shield to teach STEM / basic robotics

Current state: planning

Goal

Create an Arduino(R) shield to help teach STEM / basic robotics

General idea

We love teaching about mechanics, electricity, electronics and robotics. ZigerBot allows us to have a robust platform to teach the very basic of all this. Participants build their own robotic platform, solder the ZigerBot shield and connect both. ZigerBot can then be programmed via Arduino IDE or ArduBlockly .

Inspiration

https://github.com/FuzzyNoodle/Fuzzy-Naked-Mega

Features for first iteration

• Arduino compatible with Atmega2560 and CP2102
• Power-Input: Drives ZigerBot and powers Arduino
• Drives two DC motors, connect with screw terminals (DRV8833PW)
• Prepared for 1-2 Ultrasonic Range Sensor (SR04)
• Has an RGB LED matrix (5x5 or bigger, WS2812B)
• Can play simple melodies or signal tones
• Has 4 tactile button inputs
• Has 1-2 potentiometers
• Has 4 Servo Outputs

Dependencies

• FastLED Library
• Arduino Bootloader

Pin Configuration

We try to minimalize conflicts with different in- and output components and their libraries.

~ PWM

• Timer 0 is used by delay(), millis() and micros() - these functions are useful to beginners
• Timer 2 is used by the tone library
• Timer 5 is used by the servo/megaservo library for up to 12 servos
