This circuit is designed to monitor environmental conditions and control peripheral devices. It features light and temperature/humidity sensing, visual output on an OLED display, and actuation of a fan, water pumps, and a stepper motor. Power management and distribution are facilitated by splicing connectors, and the system is controlled by an Arduino UNO, which currently has placeholder code for customization.
This circuit integrates multiple Adafruit DotStar LED strips powered by 12V power supplies, with ground connections managed through WAGO splicing connectors. The setup is designed to provide a stable power and ground distribution for the LED strips, ensuring synchronized and reliable operation.
This circuit is an automated irrigation system controlled by an ESP32 microcontroller. It uses soil moisture sensors and a DHT22 sensor to monitor environmental conditions, and controls water pumps and solenoid valves via a relay module to manage water distribution. The system also includes an RTC module for time-based operations and connects to a WiFi network for remote monitoring and control.
This circuit is designed to automate irrigation and well pump control using a Wemos D1 Mini microcontroller. It includes a 4-channel 5V relay module for controlling 24V irrigation valves and a separate relay for a 220V well pump, with power supplied by a 5V power supply and a 220V to 24V transformer.

Usage Instructions
The WAGO 221-413 is designed for ease of use, even for those with minimal experience in electrical work. Follow these steps to use the connector effectively:
How to Use the WAGO 221-413
Prepare the Wires:
Strip the insulation from the wire ends, leaving approximately 10–12 mm of exposed conductor.
Ensure the wire ends are clean and free of damage.
Open the Lever:
Lift the lever on the WAGO 221-413 to open the clamping mechanism.
Insert the Wire:
Insert the stripped wire end into the connection point until it reaches the stop.
Close the Lever:
Push the lever back down to secure the wire in place. The transparent housing allows you to verify that the wire is properly inserted.
Repeat for Additional Wires:
Repeat the process for the remaining connection points as needed.
Inspect the Connections:
Check through the transparent housing to ensure all wires are securely clamped and properly positioned.
Important Considerations and Best Practices
Ensure the wire insulation is stripped to the correct length (10–12 mm) to avoid improper connections.
Do not exceed the voltage and current ratings of the connector (450 V AC, 32 A).
Use wires within the supported size range (0.14 mm² to 4 mm² or 24–12 AWG).
Avoid using the connector in environments exceeding the specified operating temperature range (-20°C to +85°C).
For safety, always disconnect power before working on electrical connections.
Example: Connecting to an Arduino UNO
While the WAGO 221-413 is not directly used with microcontrollers like the Arduino UNO, it can be used to simplify wiring in projects involving external components such as sensors, motors, or power supplies. Below is an example of how to use the WAGO 221-413 to connect a 12 V power supply to an Arduino project:
// Example: Using WAGO 221-413 to connect a 12 V power supply to an Arduino project
// Note: Ensure proper voltage regulation to avoid damaging the Arduino.
#include <Arduino.h>
void setup() {
// Initialize the Arduino (no specific code needed for WAGO connectors)
Serial.begin(9600);
Serial.println("WAGO 221-413 connection example.");
}
void loop() {
// Example loop code (not directly related to the WAGO connector)
Serial.println("Arduino is running...");
delay(1000);
}
Troubleshooting and FAQs
Common Issues and Solutions
Issue
