12W Dimmer with Soft Start for 12V LEDs
The circuit presented here is a LED dimmer with a soft-start function.
Getting Started with STM8S using STVD and Cosmic C Compiler
Last time we examined how to program the STM8s microcontroller using the Arduino IDE.
8 Channel Inductive Load Driver Arduino Shield
The 8 Channel Driver Arduino UNO Shield is designed to enable users to switch inductive loads for up to 800mA each channel and up to 24V DC with no heat-sink needed.
Audio VU/Sound Level Meter with LM339
This is an “Audio VU Meter” or “Sound Level Meter”, it is a general-purpose bar-graph Audio VU meter designed for fun projects.
Programming STM8S Microcontrollers using Arduino IDE
While full-time embedded firmware developers like me may always have one thing or the other against the Arduino IDE, the truth is, the IDE remains one of the most versatile and widely used embedded development platforms in the world today.
Photodiode Amplifier for Visible Light Using OPA381 – Arduino Nano Shield
The project presented here is a photodiode amplifier for visible light.
ATtiny85 push-button power switching: software-only solution
In recent tutorials, we have highlighted how useful the ATtiny series of microcontrollers are, thanks to their tiny form factor and a decent amount of processing power, which makes them good choice for projects.
Dual USB Host/Hub Output with Constant Current Limit/Protection
This project has 2 outputs that enable us to power up 2 USB devices simultaneously from an input supply of 12-30V DC.
HV Nixie DC-DC Switching Power Supply
Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed.
USBASP Firmware update guide
The USBASP programmer is an important tool/accessory for embedded systems engineers/ firmware developers.
Programming the ATtiny10 with Platform.io IDE
The ATtiny10 is a high-performance, low-power Microchip 8-bit AVR RISC-based microcontroller which combines 1KB ISP flash memory, 32B SRAM, 4x...
Sensirion Gas/Temp/Humidity Sensor Kit
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.
