• Parallax Continuous Servo Motors (part no.900-00008) (x 8)

Introduction to the Arduino

All students are expected to do a few experiments to get them familiar with the Arduino and to introduce them to C-programming. The experiments and prorgramme is described at The Arduino Microcontroller

Equipment per set

A starter kit with the Arduino, breadboard and platform. These generally include an assortment of components. We have a choice here: either get just the Arduino, platform and breadboard and decide on the other components ourselves, or get one of the kits from Adafruit or elsewhere which include all parts. Options are:

• Experimentation kit from Adafruit ($85) This is the full kit with components.

• The Arduino Started Kit This is more elaborate and is from arduino.cc (Italy). (€80) Includes a lot of components we may find useful for other experiments.

These kits tend to get out of stock so they need to be purchased well in advance.

Or we get a stock of these and add our own components:

• Plastic mount, screws and feet ($5)

• Arduino Uno R3 ($29)

• Half-size breadboard ($5) These fit on the plastic mount.

To these we'd need components that would include:

• USB cable

• Reb LEDs We'd need an assortment of these in different colours. About 16 per kit.

• Tactile buttons about 6 buttons per set. These can be purchased in bulk for next to nothing.

• Shift registers One per set.

• TS922 Dual Op-Amp This one works at lower voltages and is best suited for the Arduino.

• IR LEDs Needed as spares for the BOE Bot

• Diffuse RGB LEDs (20)

• Photocells Two per kit

• IR sensor Two per kit

• Force-sensitive resistor One per kit

• NPN Bipolar Transistors (PN2222) - 10 pack Two per kit.

• Breadboard wires One set per kit.

• An assortment of resistors, capacitors, knobs (pots, small for breadboards)

The do-it-yourself option may not be the route to take this time. We may want to get the kits now and augment them with our own components later.

BOE Bot

The Board of Education Bot can be purchased from Parallax or Adafruit:

• Adafruit: BOE Bot ($119, Arduino not included).

• Arduino Uno R3 ($29)

• Batteries (5 AAs per set)
• USB cable
• Spare parts:
  • Phototransistors
  • IR LEDs
  • IR sensors

  • 1K & 10K pots (small, they need to fit on the tiny breadboard)

Theremin

• Arduino Uno R3 We can re-use the mounted Arduinos from the first part of the experiment.

• Large breadboard - the kind we use in the lab.

• 9 x 22 kOhm resistors 1% metal film (may be best to get the resistors in kit form but this is overkill unless a use is found for the other resistors.)

• 7 x 10 kOhm resistors 1% metal film

• wire jumpers (Farnell seems too expensive. Amazon has sets for £2-4.)

• 2 x TS922IN IC, OP AMP, DUAL RRI/O, DIP8, 922 (Farnell # 1094390)

• 3 x 3310C-1-103L POTENTIOMETER, 10K 3310C-1-103L (Farnell # 9353844)

• 8 ohm speaker (Farnell: 1675522)

• Capacitors 0.01 microF, 0.1 microF and 220 microF (suggested kits ceramic capacitors and electrolytic. Both will be needed)

• Mounted breadboard (Amazon. Farnell is too expensive.)

• Small breadboard (optional- for pre-assembled op-amp parts) (Amazon)

• 2 Phototransistors (Farnell #1497882), alternatively, two photoresistors.
