18X System - Getting started

The 18X system was developed with several schools as an ideal introduction to robotics and microcomputer programming.

The main microcontroller is the popular PICAXE 18X device and the board is targetted to motor control with DC motors and servo motors. 18X system uses standard screw terminals for motors and switches. Servos connect with the industrial standard three pin connector.

The expansion port uses special push-pull connectors that make it easy to connect sensors such as ldr’s and thermistors. The i2C expansion port is also available on this connector.

Package

Supplied in kit form with all components, connectors, sample DC motors, training manual on CD.

Features

• Two colour leds show motor direction
• Two servo motor connections with standard pin out
• Two switch inputs with pull-up resistors on board
• Infra red in for communication at 38KHz from standard IR remotes ( Sony code)
• Expansion header brings out main sensor lines and I2C lines SDA and SCL
• Reset switch
• Programming connector
• Power in for voltages from 7 to 12V DC input
• Buzzer with amplification
• Led on a microcontroller line for visual indication

Ideal system for electronics education

The system has a good selection of devices that introduce modern electronics : Voltage regulator, diode, electrolytic capacitors, tantalum capacitors, ceramic capacitors, transistor, integrated circuit, leds, transistor, infra red communication device, connectors, switch, expansion headers, programming port and resistors..
