Most of the demonstrator boards starting from very simple ones to high end are having a LED or several with hardware which can make appropriate illumination. What makes…

How to make a working RS232 – TTL level converter using MAX232

Today, most of the latest microcontrollers are integrated with at least one USART (Universal Synchronous Asynchronous Receiver Transmitter) peripheral. A well set module is very useful not only to establish a communication medium (receive or transmit data) between microcontroller and PC but also to program the device via preloaded boot-loader. Here is how to make proper level converter using…
