Microcontroller training board project & workbook (PICAXE)

This resource is based on the construction of training board using the guide provided. A ten page workbook guides students through practical activities to investigate the function of various commands.

A PCB design and construction design sheet is provided to allow the manufacture of the training board by students or technician. The project is based on a PICAXE 18 microcontroller. A PCB design is provided but for a copy of the PCB layout in CWZ format please contact: ed@clarvis.co.uk (TES does not allow the attachment of these files), with a bonus 8pin and 18pin PICAXE download PCB.

• The training board consists of:
• 4 coloured LEDs connected to outputs
• A piezo sounder
• Two push switches connected to digital inputs
• A reset switch
• An LDR connected to analogue input
• A thermistor input connected to analogue input
• A potentiometer connected to analogue input
