The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers. It is a USB ICSP (In-Circuit Serial Programmer) that allows developers to easily upload firmware/bootloaders on AVR microcontrollers. Unlike what you find to serial programmers like...

The ATtiny10 is a high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller which combines 1KB ISP flash memory, 32B SRAM, 4x general-purpose I/O lines, 16 general purpose working registers, a 16-bit timer/counter with two PWM channels, internal and external...

While browsing through the internet to check up on the latest air quality sensors for use in a project I am working on, I stumbled across the Sensirion environmental sensor shield. Examining the features of the Kit I stumbled on an interesting project based on this Kit. The project was...

This is a minimal and small clock based on PIC16F628A microcontroller and DS1307 RTC IC. It is able to only show the time on a small 7-segment display with a total of 4 segments. The display we used is a 0.28" SR440281N RED common cathode display bought from LCSC.com, but you can use...

While the Arduino series of development boards have ease-of-use features that have made them a darling of the community, there are several situations where using them is not an advisable course of action for a project. Especially in projects where the developers desire a small form factor...

I have always believed that one of the best things about being a maker, is the ability to build your own tools, and we have covered the development of several tools like this in the past. For today's tutorial, we will add another tool to the list, as I will be sharing a guide on how you...

The circuit shown here is a compact and high-efficiency boost converter that has been designed for hand-held equipment. This boost converter converts 2 cells (3V) DC power into 5V DC with output load current up to 500mA. Typical efficiency when boosting battery inputs is 85%. The...

This Arduino shield helps to drive various loads like a solenoid, valve, motor, inductive actuator, heater, and bulb. A wide supply range 8V-60V and a load current of 2.7A allows it to be used with a variety of actuators. The board can be used as a stand-alone driver or it can be...
