Neural Networks For Electronics Hobbyists- A Non Technical Project Based Introduction 〈Top 20 Limited〉

Build the tap switch. Train it. Then unplug the USB – it still works. That’s your first embedded neural network. No PhD required.

After 20–30 training examples, the weights change so that your pattern activates the neuron, while random knocks don’t. The beauty: After training, you upload a new sketch that only has the final weights . No training code. The neural network is now "frozen" into your hardware. Build the tap switch

// Final weights after training float weights[] = 2.1, 0.3, 4.5; float bias = -2.8; void loop() float t = measureTapPattern(); if (neuron(t)) digitalWrite(LED, HIGH); float bias = -2.8
