Building Artificial Synapses with LEDs: A Hardware Approach
2025-01-26
The Global Science Network demonstrates how to build artificial synapses on a breadboard using LEDs as optocouplers. The article details the components of an artificial synapse: an inverter, an optocoupler made with two LEDs, an output buffer, a diode, and a variable resistor. Inhibitory synapses require an additional discharge transistor. Each synapse adds or removes charge from the postsynaptic neuron. For functional equivalence to biological cells, a proportional number of states must be transferred compared to the biological network. The accompanying video provides a more detailed explanation.
