Technical requirements

This chapter will have a practical element where you can try building the circuits that are in the book. The best way to learn is by doing. These are the recommended items for the circuits. Note that for easier sourcing, all of these items can be purchased in a single kit, including the technology and fabrics, with additional items for future chapters (not including the multimeter) from https://www.tinkertailor.tech/product-page/busy-new-bee:

• Various LEDs, a 5 mm through-hole, and sewable LEDs.
• 220 Ohm (also noted as Ω) /330 Ohm resistors.
• A 3V battery (CR2032), which is also called a coin cell.
• Crocodile clips; 5 or 10 is a good number.
• A breadboard; you can use half sizes or full sizes.
• Hookup wire:

This is measured in gauges, for instance, around 22AWG solid core will make prototyping easier for these circuits; 1 meter will be enough. When using a hookup wire for a breadboard, a single-core wire maintains its shape...
