2016年3月12日 · Ground is just the part of the circuit that directly connects to the negative terminal of your power supply or battery. It's the line at the bottom of the schematic. There's not much significance to the "GND" symbol in this case. If you're using a solderless breadboard, usually you'll use the strips marked "-" for ground.

2022年3月20日 · \$\begingroup\$ Note also, for future reference, that the supply lines running up and down the side of the breadboard are usually not connected across the breadboard, so if you wanted to use the power supply positive on the other side of the breadboard as well you would need to have a jumper wire spanning from some hole on the left-positive ...

2013年3月25日 · Look at the picture of the breadboard - bottom right-hand corner - there is the ground connection: - If you have a multimeter, check to see if this connects to the metal parts of the bnc connectors and if it is use this as ground. If you can't find this point connecting to anything then use ground as the shells of the bnc connectors.

2020年1月20日 · On a breadboard, I tend to use the bottom one of the long common rails as the ground or common terminal. This is because ground tends to be the terminal with most components connected to it. If you connect meters, or 'scopes, or signal generators, you usually need one connection to the ground terminal.

2023年4月14日 · \$\begingroup\$ If you want to try it - and I suggest you do - get sheets at least 0.1mm thick, and have them extend about 5cm outside of the breadboard, like if you had a 5cm margin between the sheet edge and the breadboard edge. Connect short ground wires from each "0V" point in the circuit to the nearest point on the sheet and solder them ...

2013年5月11日 · I'm going to play the devil's advocate and say that it is correct, within the context of a breadboardable circuit. As nice as a star ground topology sounds, a breadboard has no practical way of keeping return loops small. The bus bar is thick and relatively wide, and will have low inductance and dc resistance compared to the wires in a star ...

2016年5月29日 · I have a microcontroller circuit on a breadboard that I want to to connect to my PC via a RS-232 interface through a MAX232 IC. The breadboard is connected to an external power supply. One of the pins from the RS-232 needs to be connected to ground. When I connected it to the ground of my breadboard I blew out the fuse in my power supply.

The probe ground clips go to a short wire coming off the breadboard with ¾ inch or so stripped end. This allows for two scope probe ground clips to attach. Now you just plug the other ends of the 24 gauge wires into whatever pads on the breadboard you want to see the signal of.

2015年1月14日 · What is that "ground" thing anyway? I have batteries and LEDs and resistors in my parts drawer. But I don't have any "grounds". As such, the resistor as you've stuck it in the breadboard isn't "like" a parallel circuit. It is a parallel circuit. There's no requirement for "ground" to be involved. The laws of physics have nothing to do with ...
