⭐ Metal #detector simple circuit diagram
How it works❓- when the LC #circuit that is L1 & C1 has got any resonating frequency from any metal which is near to it, an #electric field will be created which will lead to induce current in the #coil and enable the output of #oscillator TDA0161 #IC to high, that turns the buzzer ON.

Develop a PLC-based ladder logic program for automatic packaging system according to the logic given below,
Start and stop PB is used to start and stop the whole process
Photosensor is used to detect product.
Once the count reaching 10, the robot arm takes responsible for packing.
Packing complete sensor turns on to restart the process
Stop PB is pressed any time to stop all processes.
Start/Stop Pushbutton (PB) latched with memory B3:0/0.
B3:0/0 enabled to turn on Conveyer motor (O: 0/0). Rung 0002:
Photo-sensor (I:0/1) is connected to one shot to give one pulse when a product crossing photo-sensor.
The counter is used to count the number of the product. Robotic arm for packing (O:0/1) is connected in the normally closed contact to give interlocking with conveyor motor.
Counter done bit turns robotic arm for packing (O: 0/1) to turn ON and conveyor motor to stop.
Packing complete sensor (I:0/3) or manual counter reset (I:0/4) is used to reset the counter which will turn on conveyor motor to start the process again.
Conveyor Motor (O:0/0) is connected in the normally closed contact to give interlocking with a Robotic arm for packing output.
We can use this example to understand the ladder logic in AB Programmable Logic Controllers.

Sure automation is great. After all, who the heck wants to be burnt out because they're trying to do 10,000 things all the time??
But if you are automating all the things in your business, how can you really connect with your audience one on one? You still need a "human" element somewhere in there; someone to reply to comments on social platforms, answer messages and Email inquiries, create and post consistent high-quality content... because let's face it, people buy from you because of YOU.
Does that all sound overwhelming to you? You're probably already drowning in work, your anxiety is kicked up--I get it trust me.
But see, that's why people like me exist. To take some of these burdens off your hands...so you can get at least some of your sanity back.🙌
Head to our website now to book a free consultation. We'd love to work with you!!
So excited for the app to hit the shelves in the next month.
It's amazing to build something for the industry that i use everyday.. We will be looking for Beta testers from January the 1st who will get to shape the way the app moves into the next phase

Martin Ford is a futurist and the author of the bestselling, award-winning Rise of the Robots: Technology and the Threat of a Jobless Future, Architects of Intelligence: The Truth About AI from the People Building It and The Lights in the Tunnel, as well as the founder of a Silicon Valley-based software development firm.
In today's episode we discuss:
- How will automation affect capitalism, the economy, and society as a whole
- Is UBI the answer or a NEEDED solution to an increasingly automated world
- Why AI has the possibility to solve so many of the world's largest problems
- Will AI create or destroy more jobs in the long run
- Why a universal basic income necessitates a more isolationist world
- Could climate change and automation be the recipe for disaster
- How do people find meaning in a jobless world
- Is China's social credit system an inevitable future for us all
- How should we think about lethal autonomous weapons which save lives
- Is AI bias actually a big deal
- Which technologies is Martin most worried about

Considerada a 4ª cultura mais importante da agricultura brasileira. Mato Grosso concentra 64% da produção da pluma e na Bahia chega aos 25%, e os desafios tecnológicos podem ser aliados essenciais para o aumento de produção e qualidade da pluma. #cotton#agribusiness#cottongin#agrautomacao#automation
