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
How to Use the WAGO 221-413 in a Circuit
Prepare the Wires: Strip the insulation from the wire ends to expose approximately 10–12 mm of conductor.
Open the Lever: Lift the lever on the WAGO 221-413 to open the clamping mechanism.
Insert the Wire: Insert the stripped wire 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.
Important Considerations and Best Practices
Ensure that the wire is stripped to the correct length (10–12 mm) to avoid poor connections.
Do not exceed the voltage and current ratings of the connector.
Use wires within the specified size range (0.14 mm² to 4 mm² or 24–12 AWG).
Inspect the connection through the transparent housing to confirm proper installation.
Avoid using the connector in environments exceeding the specified operating temperature range (-20°C to +85°C).
Example: Connecting to an Arduino UNO
The WAGO 221-413 can be used to connect wires from sensors, actuators, or power supplies to an Arduino UNO. Below is an example of how to use the connector in such a setup:
Strip the wires from the Arduino's power supply and the wires leading to the Arduino's VIN and GND pins.
Use the WAGO 221-413 to securely connect the power supply wires to the Arduino wires.
Verify the connections through the transparent housing.
// Example Arduino code for a simple LED circuit
// Connect the LED's positive lead to pin 13 and the negative lead to GND
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output pin
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}
Troubleshooting and FAQs
Common Issues Users Might Face
Loose Connections: If the wire is not properly secured, it may cause intermittent connections or failure.
Solution: Ensure the wire is stripped to the correct length and fully inserted before closing the lever.
Overheating: Using wires outside the specified size range or exceeding the current rating can cause overheating.
Solution: Verify that the wire size and current do not exceed the connector's specifications.
Difficulty in Lever Operation: The lever may feel stiff or hard to operate.
Solution: Ensure the lever is not obstructed and apply steady pressure to open or close it.
