This will be a different format than last time.  This week will be the “Arduino Challenge”.  The basic idea is that I will list several simple to mildly challenging things to do with your Arduino.  All challenges will use things that we have covered (successfully) at least once.  I will not divulge the details of…

This agenda is subject to change until the week of the 8th. Arduino night will kick off again on the 8th of March. Here is the proposed agenda: Agenda: 1. Using Python to communicate with Arduino 2. H-Bridge motor control (this is one not for sure just yet!) 3. Infrared detection (not actually decoding messages…

The next Arduino Night will be request driven. See below for the current agenda Agenda: 1. Transistors (LEDs, and motors) 2. Reading datasheets 3. Interfacing with SRAM Required Items: 1. Arduino (Uno or better) 2. Laptop (needs to have the Arduino software loaded) 3. Breadboard 4. Jumper wires Provided Items: 1. SRAM 2. Motor 3.…

We will pick up from last time with R2R ladders and operational amplifiers. If you have an oscilloscope, please bring it! By then end of the night we should be playing music through our Arduinos.   Agenda 1. Operational Amplifiers (voltage feedback only) 2. Digital to Analog Conversion (R2R Ladder) 3. Sampling Audio With Arduino…

We will cover how to use an operational amplifier to both amplify a signal, and add DC offset.  Then we will go over how to use a R2R ladder to convert digital to analog.  Finally we will combine both to have the Arduino sample audio using it’s A2D converter, and then spit it right back…

This Friday’s Arduino Night will be the same agenda from the one that was cancelled last week. Agenda 1. LCD character displays (16×2) 2. Digital Potentiometers (SPI) 3. Talking to other Arduinos (Protocol TBD) Required Items 1. Laptop 2. Arduino (any kind will do) 3. Breadboard 4. Jumper wires 5. USB cable for your Arduino…

Due to the instructor getting ill, the class for 11 Jan has been cancelled. Please check the mailing list for details about a possible rescheduling. UPDATE: For those who are interested, several members will be at the space tonight for an impromptu Show and Tell night. We’ll talk about our projects, help answer questions and…

Back by popular demand! Please make note of the fact that the time is back to the normal 7 PM instead of 6 PM. Agenda: Transistors for LEDs and motors (a repeat, but really important!) Shift registers to control LEDs (and possibly 7 segment displays) Using tactile switches (including de-bouncing) Talking to other Arduinos (I…

Agenda 1. Transistors (should have done this at the last class). Using them to turn on LEDs and DC motors. 2. Two way communication to the Arduino using Serial.read() and Serial.println(). 3. Using tactile switches (tiny buttons) to toggle two LEDs. Requirements Arduino of some variety. Laptop with USB ports. Breadboard of some type. Full…
