This is a 20-channel relay module that uses an analog signal as a detector for PLCs or a simple burglar alarm. Connect the module to a 24V power source. Use analog signals to activate relays.

Before today, we probably would have said that scratch-built relay computers were the sole domain of only the most wizardly of graybeards. But this impressive build sent in by [Will Dana] shows ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed ... The predicted DP-SFG parameters are then translated to transistor ...

Basically we have the Arduino Uno R4 which will read the soil moisture level using the soil moisture ... correctly as per the above circuit diagram. Note that we can't directly drive the water pump ...

The salt allows electricity to flow through the dough. With the addition of a homemade dough that substitutes sugar for salt, the dough becomes resistive instead, and complex circuits can be created ...

Abstract: This paper presents the use of nanoscale perpendicular spin transfer torque magnetic tunnel junctions as magnetic sensing units in which the conditioning electronics consists of simple ...

LED2 turns on in order to indicate when the relay is turned ON. LED1 indicates the circuit is powered ON. An SPDT switch S3 is used to switch the circuit ON. Capacitors C2 and C4 are used to filter ...
