This week we look at an easy GPS tracking unit using an Arduino and GPS shield.
This week mike takes a look at some viewer requests. One a complete failure and the other may be working, but if it is working it is weird.
This week on Let's Make It we have an Arduino control a servo like you find in model airplanes and cars. In the process of showing you how to control a servo we also introduce the concept of Pulse Width Modulation (PWM) and Pulse Position Modulation (PPM).
This week we attach a keypad to an Arduino and show you how you can easily accept input. Then we build a combination door lock with that same keypad. For both projects we also use the serial LCD that we learned in Episode 5.
This week we do step 1 of our on-air light. We make the arduino check the status of the live Ustream channel.
To do this we use an ethernet shield to poll the Ustream API to check the status of our strem. We learn how to setup the ethernet shield and then poll a web server.
We also introduce you to JSON and a new JSON Library in this episode of Let's Make It.
This week on Let's Make It we build a random dice roller. We learn how to use randomization in our Sketches. This project will randomly roll the die between 15 and 25 rolls before landing on the final number.
This week we create a working stoplight with an Arduino. And we go so much further than just blinking lights. We have 2 stop lights and sensors to know when a car is waiting.
Also, in this episode we introduce state tables and a new structure that we have not talked about before, the switch or case statement.
You even get to see me mess up by not saving my examples before the show. But this is good because it demonstrates just easy it is switch the cascading if-then-else to a switch/case structure.
This week we teach the Arduino Morse Code. We send your messages via Morse Code.
This week on Let's Make It we have some sensor fun. We play with 5 different sensors connected to the arduino. And you get to watch as we have a colossal failure with one of the sensors. We did not edit it out so you get to see the problems we had. Funny how things stop working when it is show time.
We show you the Virtuabotix DHT11 Digital Temperature / humidity sensor, The Virtuabotix MMA7361 Three Axis Accelerometer, the HC-SR501 Human Sensor Module (motion detector), The Ultrasonic HC-SR04 Distance Sensor, and our big failure this week, the SainSmart Color Recognition / Discrimination Sensor TCS3200d / TCS230D.
We will give you a schematic so you can quickly connect an LCD to your Arduino. You will learn how to scroll text, blink text and much more.
In this episode we pick up where we left off last week and add in a breadboard with some buttons to show how the Arduino can take input from the outside using something as simple as a button.
We also cover what button bounce is and some features that are built into the Arduino that will pull a pin to high so that you do not need a resistor in the button circuit. Lots of good stuff this week.
In this, our 2nd episode of this new show we take a look at the Arduino and everything it can do. Then we get our hand dirty by creating a couple of programs (called Sketches in the Arduino). The programs are very simple, so do not worry, no prior programming experience is necessary.
