    • … the power and ground pins. R1 and R2 hold the I2C clock and data bus at 5volts. We’ll use an LED to test the chip’s output features; P0 is connected to LED1 through current limiting resistor R3 (330+ ohms). P6 and P7 are tied to known states so we can easily test the chip’s input capabilities …

    • … cathode-biased amplifiers cannot be adjusted other than by changing the value of the cathode resistor(s) so this method does not apply to them. BE AWARE THAT THE ACCURACY OF THE RESULTS YOU OBTAIN WITH *ANY* BIASING METHOD WILL BE DIRECTLY AFFECTED BY THE QUALITY OF YOUR TEST EQUIPMENT, AND YOUR …

    • … not seeing each other. From there I headed to the classroom where I learn Physics (2) and waited for the lecture. The Physics (2) lectures was more on Electrical Circuits, including RC (Resistor/Capacitor) Circuits. It’s really cool to see how the differential equations we learned last semester come …

    • … on the second test I realized that the motor is only about .1 ohms. How on earth can I be feeding 15V to .1 ohms and only drawing 20 amps? Including a current-limiting resistor doesn’t improve things much, since it just wastes a bunch of power getting really, really hot. After a little thought, I decided …

    • … the resistor, just make sure it is covered with tape or any other insulator and you can leave it hanging in a safe area on the engine bay as long as it doesn’t receive too much heat. Now just do a test drive. How was it? Anything? No? No problem, you are not the only one. Extra info: As mentioned …

    • … Let me know with a comment. How to build Your Own Oxygen Sensor Simulator! The rest of the page shows how to build an oscillating signal generator with just the right frequency and voltage to fool the ECU. It is based on classical astable operating mode of 555 timer, so nothing revolutionary …

    • Difficulty Level Objective In this experiment you will test if the length of a pencil resistor effects the output of a circuit. Introduction Introduction Electricity is a very important part of our modern world and none of the modern technology we use today could exist without it. All of our modern …

    • … in this test Preparation: First, you will want to tape off the mod area, as carefully as you can, using the electrical tape. Cut short 1-2″ pieces and place them around the resistor to prevent damaging other components on the PCB. Making sure to leave a small opening in the center, for us to solder our VR …

    • … is energized, the EOL resistor is placed in a series loop as seen by the zone input. The value of the resistor varies with the panel used and in the diagram a resistance of 1000 Ohms is used, but the key point to remember is that when the situation is normal, the zone input “sees” the resistor. Electrically …
