Code for making the light

Before coming in Blue stamp I didn’t know how to code or what engineering is. Now that I finished with my two projects, I am so proud of this whole journey and what I built. I am so glad I didn’t give up and learned something I never know before. This was a good experience.

My final project is a Kaleidoscope Neopixel goggle. I used costume goggles, two NeoPixel rings, a Trinket M0, Trinket Mini Microcontroller, a JST connector, a rechargeable 150mAh LiPoly battery, enough wire for all the connections, plus a USB battery charger. It was my first time using the Adafruit Trinket microcontroller, so it can work through the Adafruit Trinket M0. I used Arduino code to make it blink first. While coding I used the breadboard for a temporary prototype with electronics and test circuit designs. The breadboard has terminals and holes to make electronic connections. Then I soldered and tinned the JST socket to the trinket to be able to connect the battery. I had to be very careful how I soldered it and had to make sure it didn’t overheat. Then I had to put the parts together on the breadboard like the circuit diagram. First, I had to solder one end of the 3-wire cables to the IN, V+ and G points on the two NeoPixel rings. There are two V+ and two G holes on each ring. Then after that, I connected to rest of the wires to the empty spot. I plugged my first ring into the trinket pin, #0 into the input. BAT+ and GND can go to either V+ and GND. After I finished putting together the parts, I coded the Neopixel by using Arduino code. Then I pluged the battery to see if it work when on the final assembly. The final Assembly is to super glue all the parts onto the goggle. I traced one of the lenses on a piece of paper so it can shine through the LED lights. How it works is to use the battery and plug into the JST that connect to the trinket, Wait for 5 seconds and you will have a LED neopixel goggle that you can wear. I learned so much from this experience like how to solder, code to make the LEDs work, to be very careful and see what you are looking at, study something that is coming apart, and how wires work.

Starter Project

My starter project is a flashing European Siren, It can be used as an intruder alarm, bicycle siren, or just plain attention getter. This project is mainly doing a lot of soldering, I learned how to do basic soldering and how the circus board works. When I solder I apply a small amount of solder to the iron tip, it allows the heat to leave the iron and onto the foil. Something I learned about soldering is to make sure it fits tightly and to not overheat the chip. In the circuit board there are symbols R1-R9 that mount the resistor flat against the PC board and they are all ¼ W resistor. The resistor is used to control the flow of electricity in the circuit. C1-C5 is electrolytic capacitors that have polarity, I mount them with the negative lead in the correct hole. I learn about polarity which is the relative orientation of the poles; the direction of a magnetic or electric field. And the division of two opposing forces or properties, I learned that you can see what’s positive or negative by looking at how round and thin it is. Positive=the round side and the negative is the thin side. Battery snap is a way to connect to the battery so it can work when you plug in the battery. I soldered the red positive lead of the battery snap to the hole marked (+) on the PC board. Then I soldered the black negative (-) lead to the hole marked (-) on the pc board. The 555 chip is a timer and mount lc1 in the location shown onto the pc board. The notch is on the IC is in the same directions as the marking on the PC board. For the potentiometer has mount VR1 into three holes in the PC board and is used for adjusting the sound. For the jumper wire, I cut a 1” wire and strip ⅛ of insulation off both ends. The LED I mount onto the Pc board and the LED flush with the PC board and I solder in the board. The LED is for the flashlight. The transistor a semiconductor device with three connections, capable of amplification in addition to rectification. For the transistor it used as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end. I insert the speaker wire through the Pc board than insert the wires into the speaker holes and solder. The speaker is used for the siren. After completing the circuit, I insert the battery into the battery snap, the LEDs then alternate light and the speaker sounds a wobbling siren.
