Just like a PC’s USB port, the serial port on a PC can also in some cases serve as a power supply. A USB port can provide as much as 500 mA at 5V, but a serial port provides less power. Even with the ...

An UART microcontroller programmer using CH340G IC. UART stands for Universal Asynchronous reciver/transmiter Protocol and it works like this: The communication beggin with a start bit, continue with ...

As promised, this part starts with a simple programming tutorial on the PIC12F675 microcontroller which shows you how to program and use it as a simple LED flasher. It’s assumed that you have ...

Programmer for ESP8266 modules with automatic programming mode. The need has arisen for small-scale programming of ESP8266 modules. These modules are used in many IoT devices where WiFi communication ...

In last week's installment, we showed how to get started with Csound. This week we take it to the next step by constructing a homemade MIDI controller circuit and use the new device to control Csound ...

When working on a project, plenty of us will reach for an Atmel microcontroller because of the widespread prevalence of the Arduino platform. A few hackers would opt for a bit more modern part like an ...

Abstract: This paper proposes a reliable wireless configuration bits programmer for remotely resetting incorrectly-written Microchip AVR microcontrollers’ Fuses and Lock Bits. The incorrect ...
