Below is a relay wiring diagram that shows how to use a relay switch with an NPNtransistor. This is useful for when you want to control a relay from things that can’t drive relays, like an Arduino, or an integrated circuit from the4000 seriesor7400 series. The NPN transistor’s base ...
Figure 1-9Networking diagram for configuring an AP to go online in static mode Procedure Configure the switch. # Add GE0/0/1 and GE0/0/2 on the switch to VLAN 100, and set the default VLAN of GE0/0/1 to VLAN 100. <HUAWEI>system-view[HUAWEI]sysname Switch[Switch]vlan batch 100[...

First, find out which keypad pins are connected to the button rows. Insert the ground (black) wire into the first pin on the left. Press any button in row 1 and hold it down. Now insert the positive (red) wire into each one of the other pins. If the LED lights up at one of th...
pinMode (analogInPin, INPUT); //pin A0 is an analog input Serial.begin(9600);// initialize serial communications at 9600 bps: } void loop() { sensorValue = analogRead(analogInPin);// read the analog in value: // print the results to the Serial Monitor: ...
Next, you’ll set your multimeter to measure resistance by switching it to read ohms. You will want to measure the resistance between your electromagnetic coils, which is a Normally Closed (NC) circuit. On a four or five-pin relay, these are pins 85 and 86. ...
Section 1: Hybrid relay describes the hybrid relay principle. Circuit and functional diagram is the first topic to be handled followed by its advantages and drawbacks and finally the main targeted applications are listed. Section 2: SCR or triac insulated control ...
However the duration of the current handling feature of an MOV may be limited to a few microseconds only, which means the activation of an MOV under such sever situations can not be more than a few microseconds, otherwise it could burn the device and damage it permanently. ...
For a new project I need to send and read data, ASCII char numbers, from the serial port to the PSoC. I've been trying to send and receive strings from Serial Port to the PSoC 4, sending strings is easy with UART_PutString(); , but I cant read them yet. I was looking in the ...
6. If you have perform all of this tests above and the system is still not working a pin to pin voltage and continuity check is in order. This test sounds harder than it is, using a wiring diagram for you car you basically you are required to test each wire for power or ground, ...
