Exercise 1:
Today Jonas L., Aidas and I soldered our little LED-Exercise together.
At first we wanted to build a 2D Matrix out of the LEDs with separate buttons for every Light, but we decided to just handle every line of five LEDs separately in order to save some resistors and buttons.
We took 25 bright white LEDs and put them soldered them to our wires in parallel together with a 330 Ohm Resistor and a Push-Button for each set of five LEDs.
- Our 5x5 Matrix Circuit
We used a piece of cardboard and pushed some holes with a needle in it to stabilize the LEDs before trying to solder everything together.
- The soldered circuit
The estimated build time for this circuit was three to four hours.
