Memory Management and a Web Server with Arduino - Episode 49

 

This week mike survives a technology meltdown to bring some personal experiences with memory management on the Arduino, he thinks you will be surprised about how little memory there is in your sketch for the Arduino.

The RainbowDuino Woes - Let's Make It - Episode 41

This week we discuss some viewer emails, talk about the Udoo that mike got this week.  

Then Bob shows us the rainbowduino from Seeed Studio and talks about some of the problems he has had and also some of the things that he has still not gotten to work.

USB Keyboard/Mouse Emulation With An Arduino - Let's make It - Episode 34

This week we show you how to make the Arduino act like a keyboard and/or a mouse so that you can build your own controller for your computer.  In this example we use a joystick as the mouse and 4 buttons to show how you can send keyboard commands.

Multiplexing with 14-segment display - Let's Make It - Episode 29

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.

Infrared Learning Remote - Let's Make It - Episode 26

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.

LED Arrays - Let's Make It - Episode 24

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.

VU Meter - Let's Make It - Episode 23

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 peak meter.

More Shift Registers - Let's Make It - Episode 18

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?  Watch and Meet Bob.
