Silicon Controlled Rectifier

The silicon controlled rectifier (SCR) is part of the family of 4-layer silicon devices. To comprehend its structure, let's revisit the structure of a diode.

Testing your digital circuit using logic analyzer

A logic analyzer is an electronics measuring device that used to measure digital signal such as clock SPI, I2C, and UART. In this tutorial we are going to build two digital circuits and measure their digital signals.
