# pxt-ucl-junkrobot

A PXT package for University College London made junk-robot

Package is meant to work with:

* 28BYJ-48 Stepper motors

* HC-SR04 Ultrasonic sensors

###### Pin connections for stepper motors and ultrasonic sensors

* Left Motor

  * micro:bit pin - ULN2003 driver

  * PIN 1 - IN1

  * PIN 7 - IN2

  * PIN 6 - IN3

  * PIN 0 - IN4

* Right Motor

  * micro:bit pin - ULN2003 driver

  * PIN 2 - IN1

  * PIN 13 - IN2

  * PIN 14 - IN3

  * PIN 15 - IN4

* Front Ultrasonic Sensor

  * micro:bit pin - HC-SR04 pins

  * Pin 8 - Trigger

  * Pin 9 - Echo

* Side Ultrasonic Sensor

  * micro:bit pin - HC-SR04 pins

  * PIN 12 - Trigger

  * PIN 6 - Echo

##### Note

Use a separate battery pack  to power the motors and sensors

*

*four AA battery pack will suffice*

*Also please use a common GND when connecting the electronic circuit*

## Supported targets

* for PXT/microbit
