<p>The 5V Relay Module KY-019 is perfectly made for Arduino application, is part of the "37 In 1 Sensor Module Board Set Kit For Arduino".<br />It has three pins, the VCC, GND and Signal. It can act as switch if the circuit and the load circuit have different supply voltage.<br />It is commonly use if the load circuit is AC. It is a switch used to connect isolated connection from the circuit using...
Soft starter used to save plastic gears of modern cheap tools by applying less initial force. Angle grinder, Miter saw and other funny jumping during power on universal motor equipment will be happy.
* ZC detectors to syncronize TRIAC timings and detect power-on switch status on tool
* TRIAC to soft start motor from 30% to 100% power
* NOTE: Do not use smart tools with speed control...

The PCB, placed near water storage and a garden bed, uses two soil sensors to determine which area needs watering. The relays control a pump located inside the water storage and two valves correlating to the two zones monitored by the sensors. The PCB also supports a water level sensor for water storage and an external LED indicator signaling a low water level.
In this project, we will make a **4-Channel Relay Driver Module Circuit** for relay based applications. In this circuit, we have designed an isolated PCB for 4 relays. By using this **Relay Board**, we can operate 4 AC appliances at a time. We have put a three pin screw terminal blocks (NC, Nuteral, NO) for connecting appliances. Below are the circuit diagram and PCB layout designs of the relay dr...
USB RS232 Relay
The main objective of this board is to ring an school bell using a PC program written in python.
- This project is the interface of a PC to a Relay using a simple USB RS232 adapter.
- This approach was selected because the parts are easily found in any PC parts store.
- The relay is activated/deactivated using the RTS line of the serial port, any...
