We will inspect all the goods before shipment,ensure all the products at good condition and ensure the parts are new originalmatch datasheet. After all the goods are ensure no problems afterpacking, we will packing safely and send by global express.

It exhibitsexcellent puncture and tear resistance along with good seal integrity. If some of the items you received aren't of perfect quality, we would resiponsibly arrange your refund or replacement. But the items must remain their orginal condition.

At the same time, you can control 7 relays. So far, I have been using 2n NPN transistors , resistors , and diodes for controlling the relays. If you look at this circuit, this circuit consists of 7 relays, seven transistors, seven diodes, seven resistors, a lot of soldering, needs more space, difficult troubleshooting, which results in an increased price.

But what if uln was used in this circuit? So we can reduce the PCB size, we can reduce its making time, we can reduce its price. For the best understanding, we will be studying the datasheet of uln , then we will make a simulation in Proteus and write an Arduino program to control uln automatically, and then we will practically test the design on a breadboard.
