This is my second project for LED Driver based on CAT4101 IC. The first project was for single White LED. This project has been designed to drive 3 channels of RGB LEDs with PWM signal which helps to create multi-color LED light. Arduino Nano is used to generate PWM signals for RGB LEDs and board has 3 tactile switches and Analog signal input to develop various RGB LED related applications. Each channel can drive load up to 1A and input supply up to 12V DC. 1A X 3 Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs. The LED current is mirrored and the current flowing from the RSET is set by PR1. On board 2W X 3 LED are used for testing purposes.
IoT which translates to the Internet of Things has been a significant buzz for the last five years while disrupting major Industries (from Agriculture, Energy, Healthy, Sports and several others).
IoT adoption has seen rapid development in the makers’ world, with different makers and manufacturers producing various forms of boards, chips, software to facilitate quick IoT development. Boards like ESP8266 from Espressif System is used for rapid prototyping and a low-cost choice for Wi-Fi-based IoT applications. Israeli based IoT firm SensiEdge has launched the SensiBLEDuino, an off-the-shelf, hardware-ready development kit based on the open-source Arduino for rapid prototyping of IoT applications.
SensiBLE is a full fledge customizable solution for those wanting to design IoT products. It helps to fasten development with a variety of sensors onboard, along with Bluetooth LE 4.1 capabilities and a low-power ARM® 32-bit Cortex®-M4 CPU with FPU. Some of the main challenges when embarking on IoT product development are; what platform will I use? What sensors are available to achieve my goal(s)? How do I handle connectivity? What about the Cloud Platform to use, and so on. Developers or product designer always result in the use of several boards or modules to achieve this while also increasing the time to bring the product to life. The SensiBLE kit removes most of these fears; it combines hardware and software in tiny form factor to allow developers get their product to market quickly at lower development costs. (more…)
This project features an easy to use Digital to Analog converter (DAC) shield for Arduino Nano. The project is built using MC4725 12Bit DAC IC over I2C communication. The shield directly seats on Arduino Nano and also can be used as stand-alone DAC converter that can be connected to other micro-controller board with help of 5 pin header connector. Output is 0-5V. PCB jumper J1 provided to select the address in case of using multiple modules on the same I2C .
Shield also provided with high current driver circuit, which converters voltage to current and can be used to drive Laser diode or LED. Maximum possible load 500mA.

Small, versatile, fun, and inexpensive! Use the 254 word library to bring speech to your Arduino projects! Speak, Arduino, Speak!
About a year ago, I designed an Arduino shield that allowed for you to add voice to your electronic designs. I’ve since been able to minimise that design into a much less inexpensive, and smaller unit. This unit has a 254 word library that consists of colours, commands, months/days/time, numbers, directions, feelings, units of measurement, security words, math lingo, and general words; all of which are spoken by “Lucy” – A lovely female voice with an English accent! Meet “The Little Buddy Talker” Arduino compatible speech kit set! It is Production Ready, and eager to land in your hands!
The project is live on kickstarter and has 29 days to go.
Arduino Nano to PIC40/28 PIN development shield is an extension for Arduino Nano. This project is useful to create many projects using PIC40/28PIN shield published on electronics-lab.com, refer to schematic and connection diagram to use this shield. Two on board regulators are provided which outputs 5V DC and 3.3V DC, this dual supply helps many projects which need dual supply. Jumper J1 is for supply selection VCC To 3.3V or 5V, diode provided at input of regulator for reverse supply protection. Not populated J4, Close J3 to supply 5V to Nano.
2 Channel Mini easy to use Relay shield for Arduino Nano consists of ULN2003 IC and 2 Mini 12V Relays with NO/NC contacts of 2A-24V Load Capacity. ULN2003 used as Relay coil driver. Relay can be controlled from D3 and D4 of Arduino Nano. Three pin Header Connector CN1 and CN2 provided to connect the Load. Relay has normally open and normally closed contacts with 2A and 24V capacity and also can handle 120V AC but it’s not advisable. CN2 supply input 12V DC. LED D2 and D3 are the output LEDs.
1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET Preset PR1. On board 1W LED is used for testing purpose. External high Wattage LED or multiple LED string can be connected by pulling two wires from the PCB and this shield fit directly on back side of Arduino Nano. Shield also has on board tactile switch connected to Digital D2 pin using pull down resistor if required for any application. On board preset helps to set the maximum constant current. PWM input pin connected to Digital pin D6 of Nano to control the LED intensity. Example code FADE-IN/FADEOUT helps to test the shield.
