Type K Thermocouple Sensor Amplifier Arduino Shield
This is a Type K Thermocouple Sensor Amplifier Arduino Shield that enables an Arduino board to acquire temperatures from a thermocouple of type K.
12V to 24V @ 1A Step-up switching regulator using LM2585
Schematic Description This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments.
Optically Isolated Bidirectional I2C Shield For Arduino
Optically isolator Arduino Shield has been designed to provide optically isolated I2C communication between Arduino and any other device or sensors that works with I2C protocols.
Adjustable Constant Current LASER Diode/LED driver
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry.
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.
