Boolean theorems
The boolean theorems are a set of rules from boolean algebra to simplify logic expressions of combinational circuits.
Optocoupler with phototransistor
The optocoupler electrically insulates a circuit’s input and output. The operation and some projects are shown in this post.
Meet the LM3915
The LM3915 is an integrated circuit that uses many operational amplifiers to measure voltage level or audio volume.
