Arduino Class - Interacting With Arduino - Part 2

Come join us at The Forge Makerspace (located in the North Branch Library, Denton, TX) to learn about the interacting with the Arduino. In this class we will be focusing on interfacing keypads. Techniques learned here can be used on any existing microcontroller

Keypad, Part 1: Introduction (http://bit.ly/2glMwvp) (4:05) In this presentation, I will demonstrate how to connect a common 4x4 membrane keypad that contains numbers, letters “A”, “B”, “C”, and “D”, a “*” and a “#”. I will do it in two ways. First, I'll use the keypad library that comes with the Arduino IDE in a sketch that reads the keypad, while the keypad is connected in parallel. In demo 2 you learn how to hack together a solution that allows a connection that uses a single signal pin.

Keypad, Part 2: Parallel connection wiring (http://bit.ly/2fX30cl) (12:15) In this presentation, I will demonstrate how to connect a common 4x4 membrane keypad that contains numbers, letters “A”, “B”, “C”, and “D”, a “*” and a “#”. I will do it in two ways. First, I'll use the keypad library that comes with the Arduino IDE in a sketch that reads the keypad, while the keypad is connected in parallel.

Keypad, Part 3: Parallel connection sketch (http://bit.ly/2h5EtXC) (5:10) This is Part 3 of 5 of the keypad presentation. Here I describe the sketch that works with the parallel wiring of the keypad. This configuration was demonstrated in Part 2.

Keypad, Part 4: Single wire connection (http://bit.ly/2fWVVIK) (12:24) This is Part 4 of 5 of the keypad presentation. Here I describe an alternative way to connect the keypad that only uses one signal wire. The single wire configuration concludes in Part 5.

Keypad, Part 5: Single wire connection conclusion (http://bit.ly/2gZpIle) (11:30) This is Part 5 of 5 of the keypad presentation. Here I conclude the discussion of the single wire connection configuration. Parts Needed:
