Arduino Starter Kit - Project 13 - Touchy-Feely Lamp

Touchy Feely

Capacitance is a measure of how much electrical charge something can store. The library checks two pins on your Arduino (one is a sender, the other a receiver), and measures the time it takes for them to have the same state. These pins will be connected to a metal object like aluminum foil. As you get closer to the object, your body will absorb some of the charge, causing it to take longer for the two

pins to be the same.

Arduino Starter Kit - Project 12 - Knock Lock

Knock Lock

When the piezo is pressed flat against a solid surface that can vibrate, like a wooden table top, your Arduino can sense how intense a knock is. Using this information you can check to see if a number of knocks fall in an acceptable range. In code you can track the number of knocks and see if they match your settings.

Building

1. I mounted the Piezo on another breadboard all was a bit tight. 
2. The power supply on the added keyboard is not connected

Breadboard and Schema through Fritzing

1. I start to get the hang of Fritzing and the schema diagrams.
2. I managed to keep both diagrams tidy

Took a long time to make this to work, need to be more careful in breadboarding.

Resistor ladder

This is a way to read a number of switches using the analog input. It’s a helpful
technique if you find yourself short on digital inputs. You’ll hook up a number of
switches that are connected in parallel to analog in 0. Most of these will connect
to power through a resistor. When you press each button, a different voltage level
will pass to the input pin.

I had a lot of trouble relating the breadboard layout to the schematic, evidence of my being a novice. I spent a lot of time trying to understand it.
