How Do You Check Voltage With a Multimeter? A multimeter is an instrument that can measure voltage, current, resistance and possibly additional parameters. You can also use it to check continuity of cables and check fuses. If you don't know how to use one, read my guide How to Use a ...
Since the driver transistor is connected with the relay, this large reverse EMF tries to force through the transistor emitter/collector. The word "reverse" is used because this back EMF is negative in polarity. Being negative in polarity this back EMF tries to force through the emitter towards ...
You also know from that article that one way to implement gates involves relays. However, no modern computer uses relays -- it uses "chips." What if you want to experiment with Boolean gates and chips? What if you would like to build your own digital devices? It turns out that it...
Step 5 Read the multimeter. Wiggle the leads slightly if the outlet is not registering. If it still doesn't register, check the circuit box to make sure the power is on.
Check if the trunk compartment divider is in the correct position. All the pins have to be hooked into the brackets for your convertible top to engage correctly. While you’re there, check out the switch for the cargo divider by using a digital multimeter. Replacing a broken switch is simpl...
The simplest solution is to use the microcontroller itself to check: int x = analogRead(A0); static int min = x; static int max = x; if(x < min) min = x; if(x > max) max = x; Move the joystick, see what comes up, and set the range rescaling to the min/max. You can ...
The DHT11 measures temperature with a surface mountedNTC temperature sensor(thermistor) built into the unit. To learn more about how thermistors work and how to use them on the Arduino, check out ourArduino Thermistor Temperature Sensor Tutorial. ...
Test a Fuse With a Multimeter Cars and older homes that don’t use modern circuit breakers use fuses to prevent damage from electrical surges. Sometimes these fuses require testing to check that they are still in good working order. Testing fuses ca... ...
