How do I

Start?

Electronics is about dealing with signals

Let’s start with a simple circuit

Tools of the trade

Wires. Screwdriver. Pliers. Cutters.

Multi-meter.

Kits.

• ultra-small (2mm x 2mm) – WOW!

• Tri-axial• Measurement of

accelerations in 3 perpendicular axes

• Senses tilt, motion, shock and vibration

- Low power consumption of 130 μA – NICE!

Don’t be afraid to blow things up

Design your system

Apollo Guidance Computer (AGC), 1966

16-bit, 55Watts<1MIPS, 4K RAM, 32K ROM, 8 GPIO1.024 Mhz31 kilograms$15 Million

Arduino UNO platform, 2009

8-bit Atmel atmega ATmega32820MIPS, 2K RAM, 32K ROM, 14 GPIO16Mhz27 grams$20

Hardware platforms change all the time. The key is

quick adoption.

• ONE WAY VALVE• PLUS (+) and

MINUS (-) • Makes pretty

1. Pick a simple project that you can manage

2. buy tools and parts as you need

3. learn through problems

4. Have a project goal.
