So what do you do if the inputs and outputs on your Arduino are not enough for you and you need to add more. In this episode we talk about just one of the ways. We introduce you to a 16 bit I/O chip that runs over i2C. You…

This week we go through multiplexing. Bob gives us a presentation that he gave last weekend on how multiplexing works and how to use an arduino timer to help with the multiplexing. Downloads HD Apple HD Apple SD …
This week we show how you can make an infrared learning remote with an Arduino. You will be amazed how simple and how few parts are actually needed to make this work. Downloads HD Apple HD Apple SD …
This week we show you how to read a temperature sensor then we build a Thermostat that monitors the temperature and turns on the AC, Heat or Emergency Heat. Then we take it one step further and turn that same thermostat into a wireless thermostat using Zigbee to control…
This week we talk about how to use the feature packed shift register we used on the multiple 7 segment displays 2 weeks to control an LED array. Downloads HD Apple HD Apple SD Audio MP3 Circuit:…
This week we make a simple VU meter using an Arduino. We take audio input from either a microphone or a line level input and use a small transistor to amplify the signal, add some leds and some basic code to create a VU meter that has a switchable…
This week we take a look at using a shift register to control a single 7 Segment Display then we take a look at the Maxim 7219 chip that is designed specifically for controlling up to 8 7 Segment displays or an 8×8 LED matrix. Plus you can connect…
This week Bob is back and talk about how to control one and many relays with an Arduino. Also, an update on the live light project.
This week we attach a joystick control to an Arduino to control a pair of servos. It is much simpler than you think! Downloads HD Apple HD Apple SD Audio MP3 Example Code Reading Joystick Input…
This week we expand on shift registers from last week and add another chip to demonstrate how you can daisy chain them to control more things with the same 3 pins off of the Arduino. Oh, did I mention that I have a special guest on the show tonight? …
