Projects

• 7 Segment Display
• Joystick
• Get Chicken Temp
• coin exchanger.
• Leaderboards for the analog game. but also online. like olympics.io
• button for the first one. fun and games. and if press early mag error.
• Egg sorter
• Coin sorter (like from japan)
• Changing Alarm Clock Face.
• Arduino IC card
• uv dtf
• melissa
• Makerlab1231
• arduino keyboard.
• arduino camera
• arduino speaker
• arduino microphone
• That tip coin box where if you put money the monster tries to get it.

General

• Arduino nlng for being cost effective
• Unwind the damn cord before using it. Inductance is a real thing.
• multi tasking: arduino interrupts fpr multi tasking
• Positive sign (like the longer end of the light bulb) is connected to the power. And the other end (negative) is to the ground.
• Need Battery if you want to operate a component that requires more power. The default 5V from the board won't suffice.
• The color of the wires matters in some components like servo matter. The darker one is for the ground.
• The Longer Leg (Anode): This is the positive (+) side. It always connects towards your power source (the 5V pin).
• The Shorter Leg (Cathode): This is the negative (-) side. It always connects towards the ground (GND).
• You can connect the power of the component to the digital pins and not even using 5V because digital pins are just like power source that simulate strength of power and not just 0 and 1. But it just outputs not the same power as 5V, which is helpful in fading light
• Digital Pin are either the regular one or the PWM one (which is designated by ~)

Code

• There are already a lot of built-in libraries in Arduin IDE. Check Sketch > Include Library.

• The Arduino IDE has a built in function “analogWrite()” which can be used to generate a PWM signal. The frequency of this generated signal for most pins will be about 490Hz and we can give the value from 0-255 using this function.

  • analogWrite(0) means a signal of 0% duty cycle.
  • analogWrite(127) means a signal of 50% duty cycle.
  • analogWrite(255) means a signal of 100% duty cycle.
  • On Arduino Uno, the PWM pins are 3, 5, 6, 9, 10 and 11. The frequency of PWM signal on pins 5 and 6 will be about 980Hz and on other pins will be 490Hz. The PWM pins are labeled with ~ sign.

• CH340 Arduino Board

  • Seems like a different installation for Windows 10 and Windows 11.
  • For windows 10, just get the generic tutorial in the youtube like this one:
  • https://learn.sparkfun.com/tutorials/how-to-install-ch340-drivers/all
  • For windows 11, something like this:
  • https://www.visualmicro.com/page/CH340-Driver-Fix-Installation.aspx
  • ![[Pasted image 20241024212514.png]]
  • For Ubuntu 2024, seems to work out of the box. I used the portable Arduino IDE (?). No install just extract. Just needs to enable to add authority to users. Thank God ChatGPT.
