I am trying to make a two photogate experiment. The LED emitter and receiver positive end are connected to digital pins and the 5V on the Uno R3 board. Don't really want to solder. Are there connectors for Arduino jumper wire pins for two in and one out, or a good alternative for neat connection?
This can go much better if you provide even a hand drawn schematic of what you have in mind.

A breadboard
Make your own! A block of wood and some wood screws.
Here is a link to the sort of ones I use.
My bad on the drawing. I do have a 220 Ohms resistor connected.
Noticed that these LEDs need 100 mA, so I will need a driver transistor. Thanks for that.
The mini breadboard I showed is 5 sets of 5 connections. It can handle a couple of LEDs and resistors or a transistor and a couple of other parts.
Get over your reluctance to solder and make some Y leads to suit your needs
I use Wago 221 blocks. They're a bit spendy, but very high quality. They come in a variety of sizes that can be used to connect a number of wires together.
They use lever clamps, so no tools needed.
Hi Ron,
Don't know if my drawing would better explain anything, my diagrams are terrible. To better explain it, something like a Y-connector that one input leads to two outputs. Something small, like the jumper wire ends.
Making my own is a good idea. Might have a go at 3D printing a design with screws.
Been looking for some this small. Thanks.
Thank you. Have found many variations of these and will give them a try.
Didn't know about these, these are good. There are knock-offs on Amazon that are affordable.
This is exactly what I was after thank you. They come in a range of female-male connection types too.
