week-13 Output devices

Array Circuit

another assignment with electronics, but now i am excited about it.

Today i am making an Array circuit.

I love lights, hence i have choose this circuit.

Flow of work for this week as follow:

• deciding the circuit i want
• milling the circuit
• soldering all the components
• checking the working of the circuit
• knowing about the method of working with the circuit as in this week assignment there is something different than usual coding
• I have learned about charlieplexing in this week assignment for running so many LEDs together in a sequence.
• I am also trying to write letters one after one.

Circuit diagrams of Array output

Again starting with milling the circuit with fab-module software

• Settings for milling out a circuit is shown in the following image.
• blue lines shows the tool-path of the bit.
• it took 10.8 minutes for milling as shown in the image

Now consider the following image for cutting toolpath

Settings and parameters are shown in  the image

It also shows the cutting tool-path

Consider following images for fresh circuit and then i started with soldering the components

As instructed earlier, attiny 44 is soldered first, then headers

and i have tinned all the connections for mounting the resistors and LEDs.
