Jan 15, 2023 · I have 2 wires which need to connect into pin 2 on the arduino. The first wire (in brown) is connected straight into pin 2 on the arduino and to the breadboard H35. The second wire that needs to connect to pin 2 is the orange wire connected to DIR+.

Feb 20, 2024 · The idea consists of taking the insulation off of both of the wires, then tying the wires connected to the joystick and the wires that are connected to both arduino's together. In alternative terms, taking the insulation off of a segment of the wires, then interlocking the insides, so that they can both feed into the slot, and have a connection ...

Jun 6, 2022 · Hi, I wanted to know how you are able to connect two separate ground wires into one ground pin, assuming the other 2(out of the three ground pins of an arduino Uno) are taken. And without a breadboard, I really want to …

Jul 19, 2014 · I'm essentially trying to connect a sensor (motion) and radio to the same VCC or GND pins on the pro mini. So you are asking about soldering more than one item to power and ground?

Mar 24, 2024 · You can get the second 5V from the IOREF pin. This is the secret power pin. Otherwise a solderless breadboard is very convenient for this sort of thing because it provides busses to distribute power.

Aug 23, 2022 · Method 1: How to Connect Multiple Inputs to One Arduino Pin. Method 2: Read Multiple Push-Buttons using One Arduino ADC Pin. The microcontroller used in the Arduino development boards has an inbuilt Analog-to-Digital Converter (ADC).

Both i2c-interface real time clock module and 2x16 LCD module use the same pin A4 (SDA) and A5 (SCL) on Arduino Uno. After hours of searching on the net the i2c bus can actually take many serial devices.

The problem here is that single pins don't connect very solidly to the Arduino's pin headers, and can easily come out. Especially with a wearable project. I'd suggest getting a cheap proto-shield, and soldering all the wires of the components to that (maybe add …

Apr 7, 2015 · You can connect multiple components to a single ground pin. IF you are using a breadboard, be sure to put the wire going to the go

Nov 23, 2015 · You can use anything that will allow you to put 3 wires together. If your kid is handy with a soldering iron, put a wire on the board and solder the other end to the 2 wires that need to connect to that pin.
