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 simplicity and efficiency. Follow these steps to use the connector in your electrical installations:
How to Use the WAGO 221-413
Prepare the Wires:
Strip the insulation from the wire ends to expose approximately 11 mm of 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 the connection visually.
Repeat for Additional Wires:
Repeat the process for the remaining connection points as needed.
Important Considerations and Best Practices
Ensure the wire size is within the supported range (0.14 mm² to 4 mm² or 24–12 AWG).
Do not strip too much insulation, as this may expose the conductor outside the connector.
Avoid using the connector in environments exceeding its rated temperature or voltage.
For stranded wires, twist the strands together before inserting them into the connector to ensure a secure connection.
Example: Connecting to an Arduino UNO
While the WAGO 221-413 is not an electronic component like a resistor or IC, it can be used to connect wires from an Arduino UNO to other devices or components. For example, you can use it to connect power and ground wires securely.
// Example: Using WAGO 221-413 to connect Arduino UNO to an LED circuit
// Note: This code assumes the physical connections are made using the WAGO 221-413
// to securely join wires.
const int ledPin = 13; // Pin connected to the LED
void setup() {
pinMode(ledPin, OUTPUT); // Set the LED pin as an output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(ledPin, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
Troubleshooting and FAQs
Common Issues and Solutions
Wire Slips Out of the Connector:
Ensure the lever is fully closed after inserting the wire.
Verify that the wire size is within the supported range.
Poor Electrical Contact:
Check that the wire is stripped to the correct length (11 mm).
Inspect the wire for damage or corrosion before insertion.
Connector Overheats:
Ensure the current passing through the connector does not exceed 32 A.
Verify that the connector is used within its rated voltage and temperature limits.
Difficulty in Lever Operation:
Ensure the lever is not obstructed by debris or damage.
Apply steady pressure when opening or closing the lever.
Frequently Asked Questions
Q: Can the WAGO 221-413 be reused?
