Continuing the trend of motor control and transistors, we will be driving unipolar steppers motors. The motors will be provided since having varying stepper motors can be troublesome. It is suggested to bring a full sized bread board since this will take up a little bit of room! Agenda: What is a stepper motor Uses…

Last time we covered basic transistors. Just turning an LED on and off and driving a DC motor. This time we will look at creating an H bridge to drive a DC motor forwards and backwards. We will also be going a little more in depth about transistors. Feel free to bring your own DC…

I am super late getting to the slides for this class O.O The basic plan is to play with transistors to control LEDs and DC motors. If we get through everything, then the next class will hopefully cover H bridges for reversing DC motors. The agenda is short since the class could go way over…

Per a request at the last class, we will be writing to and reading from SD cards. Please bring an SD card if you can. There will only be two available for use!!! Also, the cards must be SD, not the smaller cards. All cards should be 8GB or less and be formatted to FAT16…

We will be working with SPI based SRAM. The SRAM chip will be the 23LC512 (datasheet). Agenda: What is SRAM Review datasheet Use SPI library to write to and read from the SRAM Write to and read from the SRAM by hand If you cannot attend the class in person, E-Mail arduino@unallocatedspace.org and ask to…

We are getting back to LCDs this week. The last time we dealt with a 16×2 display, we used the LiquidCrystal library. This time we are going to ‘bit bang’ the LCD by hand. The idea is to learn how to control external devices for which you don’t have a library. Agenda: Wiring up the…

We will be playing with 74HC595 8-bit shift registers. It’s okay if you don’t have one as there should be plenty to go around! Agenda: What is a shift register and what can it do Reading datasheets How the 595 works Simple shifting with ShiftOut Latching a value Simple shifting by hand Latching a value…

We are back to the regularly scheduled time! Sorry for the late notice. I put it off too long 🙁 We will be covering 16×2 LCD screens. Don’t worry if you don’t have one. I will be bringing plenty, and we have lots at the space too 🙂 We will come back to LCDs at…

THIS CLASS STARTS AT 8, NOT 7!!!!! In the last class we went over the basics of serial communication.  This class will dive a little deeper into serial by using Python to talk to the Arduino instead of the Arduino IDE’s serial monitor.  This will enable the sending of more complicated data than just ASCII…
