Tinkercad and microbit neural network In a previous post I produced a single neuron based around microbits in Tickercad - see here . To extend this the basic ideas discussed in that the previous post where extended to three microbit joined together. In  other words a network of neurones or neural network. Basic requirements of a neuron are Requirements  - By altering the bias (or w0 in the example), weights change the behaviour of switches changes. -when switch is pressed a variable x1 or x2 is set to 1 depending on which button is pressed and when released it goes to 0.  - if (bias+w1*x1+w2*x2)>=0 then a T for True appears of the LEDs otherwise F for False is shown. So by selecting the weights and connecting the outputs (p2) from the microbits labelled as Red and Green in the image above as inputs to the yellow microbit 'neuron' we can form a neural network. Switches as the inputs and the screen on the yellow 'neuron' as the output of the network showing true (T) or...
