The video below shows how to build artificial synapses on breadboards using LEDs as an optocoupler.
Most biological neurons have thousands of connections to other synapses and each connection forms a synapse. When building artificial neurons artificial synapses are likely needed to connect to other neurons.
Each synapse consists of an inverter, an optocoupler made with two LEDs, an output buffer, a diode, and a variable resistor. If the synapse is inhibitory, a discharge transistor also needs to be added.
Each synapse either adds or removes charge from the postsynaptic neuron. For these synapses to be functionally equivalent to biological sells a proportional number of states needs to be transferred compared to the same biological network. The video above describes this in much more detail.
