I was wondering if anyone could help with direction on making my idea a reality. I would like to wire the remote control of an RC car to the GPIO pins of the Raspberry Pi. I just do not know how to "make the connection" between the GPIOs on the Raspberry

Checking alternator output using an ammeter in series with the charging system should be done only by an auto-electrician. A safe test can be made with an induction ammeter held parallel to the output cable, but it is less reliable. Testing drive belt tension Check drive-belt tension on th...
1. First install a simple voltmeter in parallel with the motor and obtain the voltage across the motor.2. If you have any ammeter available to you you may use it to find the amperes across the motor. Always remember to connect the ammeter in series with the motor because ...
Connect an adjustable DC power supply, negative to the ground and positive to the BNC center pin. Also connect a DC volt meter across here. Turn the potentiometer all the way to one end. Adjust the power supply to drive the meter to the 20 different levels on its scale: 0.05 mA, ...

Step 3:Connect your adaptor to a USB battery bank and to your broadband equipment. Test to see if it works and how long it can power it for. Once done, recharge the battery and keep it ready if you need it.Please don’t leave your broadband equipment connected to the battery until it...
Voltage Definition: Voltage is defined as the potential energy difference per unit charge between two points in an electrical field. Understanding Through Analogy: Voltage can be likened to water pressure in a hydraulic system, where higher pressure pushes water through pipes, similar to voltage pushi...
(just a sensitive ammeter) needle move as i do this in the gif below. the greater the current, the greater the voltage. you don't see it in my demonstration, but the angle between the magnetic field and the coil of wire is important. this means that instead of moving the magnet, ...
How to test a car battery If your car's instrument panel includes an ammeter , it will tell you how well the charging system is working - the difference between the charge going into the battery and the power being used from it. Basics The engine - how it drives its ancillary parts The...
