Introduction to Physical Computing
12 Sep 2018
Today we had the first lab and Tom Igoe presented a basic introduction to the tools we’ll be using in class: Arduino microcontroller, breadboard, multi-meter. He showed an example of some simple circuits - introducing LED’s, switches, etc.
After class I worked in the lab. I made a pretty basic circuit using some cool toggle switches I found. Flipping the switch turns off and on the LED.
What I was working on (and eventually gave up on) was to use two led’s and toggle between them with the switch. I was able to get them to light up at the same time with the switch or all stay on. I’ll keep working on this problem as I try to understand more about wiring.
On another note I was able to get my Lolin Node MCU ESP8266 to interface with the Arduino IDE. In the past I had a lot of trouble getting it to work with Arduino, but I followed more steps to get it to work.
- Downloaded and installed driver for lolin.
- Flashed the ESP8266
- Configured Arduino IDE. I set the board to
- Make sure to check the pinout for the esp
- Make sure to set baud rate 9600
