Our team "TEENS" is working on another project called Fully Autonomous Hydroponic Farming. This presentation will help you get to know it betterβ€”it is in Uzbek, and anyone who knows Uzbek is welcome.
The following post will be about it, so everyone can get the idea.
If you have some background in this project, please reach out to @javoshka1. Maybe your knowledge will help us to succeed.

🌱 Fully Autonomous Hydroponic Farming Project 🌱

Our project is an advanced farming system that integrates robotics, sensors, and AI to fully automate the process of hydroponic agriculture. The system monitors key parameters like water levels, nutrient concentration, and environmental conditions in real-time. Using AI algorithms, it optimizes plant growth by adjusting these factors automatically without human intervention.

This sustainable approach not only reduces water usage but also eliminates the need for soil, making it ideal for urban and resource-limited areas. Our goal is to revolutionize agriculture by making it more efficient, eco-friendly, and accessible for the future. πŸš€

πŸ”§ Resistors: The Unsung Heroes of Electronics

Resistors are fundamental components in electronics, designed to resist the flow of electric current. They play a crucial role in controlling voltage and current within circuits, ensuring devices operate safely and efficiently.

How Resistors Work

A resistor reduces current by converting electrical energy into heat. Its resistance, measured in ohms (Ξ©), determines how much it restricts the flow of current. The higher the resistance, the lower the current flow.

Types of Resistors

1) Fixed Resistors: Common types include:
Carbon Film: Cost-effective, general-purpose.
Metal Film: Precision applications, low noise.
Wire-Wound: High power handling.

2) Variable Resistors (Potentiometers): Adjustable resistance, often used for volume control or sensor calibration.

Key Facts About Resistors

Color Code: Resistors use a band system to indicate their resistance. Learn the color code: BBROYGBVGW (Black, Brown, Red...White).
Power Rating: Measured in watts (W), it indicates how much heat the resistor can safely dissipate.
Tolerances: Resistors have a percentage tolerance (e.g., Β±1%) that defines how close their actual resistance is to the labeled value.

Quick Tips for Using Resistors

Always calculate the required resistance value using Ohm's Law: R=V/I.
When in doubt, opt for a higher power rating to avoid overheating.
Combine resistors in series or parallel to achieve desired resistance values.

πŸ”‹ Capacitors: The Energy Storage Champions

Capacitors are essential components in electronics that store and release electrical energy in a circuit. They act as mini energy reservoirs, balancing voltage and smoothing out power fluctuations.

How Capacitors Work
A capacitor consists of two conductive plates separated by an insulating material called a dielectric. When voltage is applied, it stores energy as an electric field. The amount of energy it can hold depends on its capacitance, measured in farads (F).

Types of Capacitors

1) Electrolytic Capacitors:
- High capacitance.
- Used for filtering and power supply stabilization.

2) Ceramic Capacitors:
- Low capacitance.
- Ideal for high-frequency circuits and decoupling noise.

3) Film Capacitors:
- Stable and durable.
- Used in precision applications.

4) Supercapacitors:
- Extremely high capacitance.
- Used for energy storage in renewable energy systems.

Applications in Robotics
- Power Filtering: Smoothens out voltage fluctuations to protect components.
- Energy Storage: Provides short bursts of energy for motors or actuators.
- Signal Processing: Removes unwanted noise from signals.

Key Facts About Capacitors

- Polarity: Electrolytic capacitors have polarity (+/-), while ceramic ones are non-polar. Always connect them correctly to avoid damage!

- Voltage Rating: Never exceed the capacitor's voltage rating. A higher margin (e.g., 20%) is always safer.

- Capacitor Charging: Capacitors charge and discharge exponentially, making them useful for timing applications.

Quick Tips for Using Capacitors

- Always choose a voltage rating higher than your circuit's operating voltage.
- Use ceramic capacitors near microcontrollers to suppress high-frequency noise.
- For power circuits, combine electrolytic (bulk storage) and ceramic capacitors (noise filtering).

Neowave - RGB WiFi Moodlamp

In this tutorial you will show you how to assemble this RGB lamp! The lamp is mostly 3D printed, and is easy to repeat by yourself. It uses an array of WS2812B individual addressable RGB LEDs, which gives it the ability to not only show every color, but also in different effects, like simulating a fire. All of this can be controlled via the app, WLED.
