The project presented here is a PWM current driver for solenoids, Relays, and valves. The board will regulate the current with a well-controlled waveform to activate and reduce power dissipation at the same time. The solenoid current is ramped up fast to ensure the opening of the...

The board presented here is multipurpose hardware which includes the ESP32-Wroom module, 3.3V regulator, 5V relay, Power LED, Relay LED, and connector to program the ESP-32 Module. The project requires 5VDC and consumes 60mA current when the relay is ON. The project can be used in IoT...

This RC Relay project enables control of large current devices using a Radio Control (RC) System. This RC switch converts hobby radio control (RC) pulses to control the on/off state of the Relay. On board LED indicates the output. The board is Arduino compatible and the example code...

This is a Smart Dual Coil Latching Relay that can control the ON/OFF power of a device by applying a short voltage pulse to Input 1 and Input 2. This project is helpful in low-power applications since the coil is not powered all the time, it only requires a short voltage pulse. Relay...

The project presented here is an over-current trip switch. It provides protection to a load when over current condition occurs. Basically, the project trips the relay when there is a short circuit or the load starts drawing much current. When the condition is favorable, press the...

This is an SPI Interface multichannel relay board for high voltage AC or low voltage DC loads. It is ideal for controlling LEDs lights, coffee machines, fans, pumps, or other high-voltage electrical appliances. The board also breaks out the SPI header, so controlling other boards is...

The project described here is a very useful device for use with linear actuators. This controller prevents the actuator from reaching the physical movement limits of the actuator, thus it prevents burnout of motor and physical/mechanical damage to the actuator itself to the...
