Three new circuits for physical computing. There are 3 circuits on this breadboard, from top to bottom – transistor toggle – the LED’s toggle when the switch is pressed, astable multivibrator – the LED’s fade in and out one at a time, voltage divider – the LED turns on in the dark. Additionally, I did my first soldering job, we had to solder header pins on to the power adaptor so it can power the breadboard.

The breadboard setup with a voltage regulator to power the board at 5V from a 9V battery. A circuit with capacitors that causes the LED to fade in and out when switched on or off.

I’m really excited to be in Physical Computing this semester. The course covers basic electronics and microchip programming. We’ll be programming PIC chips, later in the semester and building all kinds of cool things. Really looking forward to that! It brings back some vague memories of physics in college and is sure going to consume a lot of my time. The first mini project was to build a circuit using a breadboard, a resistor, an LED, a switch and a 9V battery. It seems like I’ll be doing a lot more embedded systems programming this semester in Major Studio – Computation,  where we’ll be using Arduino, IR sensors and more. Here are some pictures of my first circuit!
