Sending Morse Code with the Arduino Lessons – Episode 7
This Arduino Lessons for robotic beginners we teach the Arduino Morse Code. We send your messages via Morse Code.
Making a Stoplight With An Arduino – Episode 8
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.
Rolling The Dice With Randomization – Episode 9
This week on Arduino Lessons for robotic beginners 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.
Checking uStream With An Arduino – Episode 10
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.
Keypad Input To An Arduino – Episode 11
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.
Controlling a Servo with an Adruino – Episode 12
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).
