To show you how to wire the relay, let’s build a temperature controlled relay circuit that will turn off a light bulb when the temperature of a thermistor reaches 150°F.Thermistorsare really useful with 5V relays. You can use them to turn off a large motor if gets too hot or turn o...
A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. Relays are found hidden in all sorts of devices. In fact, some of the first computers ever built used relays to implement Boolean gates. In this article, we will look at how relays wor...

Transistors are tiny electronic components that can do a similar job to relays, working as either amplifiers or switches. Although they switch faster, use far less electricity, take up a fraction of the space, and cost much less than relays, they generally work with only tiny currents so ...

In an extremely simple circuit, you would wire a CdS cell directly to a relay (see How Relays Work), so that a lot of light would energize the electromagnet and a small amount of light would not. Usually, however, a CdS cell cannot draw enough current to activate the relay when light...
Figure 2: The NI 9246 and NI 9247 modules have CTs built into the module, large over-current ratings, and accommodate up to 10AWG wire with ring lugs for higher current measurement. Direct measurements with these modules will be more accurate and with a higher frequency response than using ...
I was wondering if anyone could help with direction on making my idea a reality. I would like to wire the remote control of an RC car to the GPIO pins of the Raspberry Pi. I just do not know how to "make the connection" between the GPIOs on the Raspberry
The MegaSurge Series of inrush current limiting NTC thermistors offer a simple and cost-effective alternative to using wirewound resistors in combination with timers and relays. These thermistors not only reduce costs but also simplify designs significantly. Moreover, they enhance safety by eliminating...
Depending upon the type of neuron, axons can be covered with a thin layer of myelin sheath, like an insulated electrical wire. Myelin is made of fat and protein, and it helps to speed transmission of a nerve impulse down a long axon. Myelinated neurons are typically found in the ...
