The Design Idea in Figure 1 indicates a low-battery condition in an audio test instrument that is powered by four AA cells. As the instrument was otherwise an all-discrete design, this same approach seemed more in keeping with the spirit of the project than the use of a single-sourced integrated circuit. A garden-variety red LED […]

Internet of Things (IoT) is one of the most important technologies these days. It became an essential component of many hardware projects core. And in order to make it easier for developers, Bolt IoT platform appeared as a complete solution for IoT projects. Bolt is a combination of hardware and cloud service that allow users
IoT Projects Is Now Easier With Bolt IoT Platform Continue Reading
Introduction Sometimes it may be necessary to use a display when making a hardware project, but one confusing thing is the size of the display and the required pins to control it. This tutorial will show you how to use a small I2C OLED display with Arduino using only two wires. Geekcreit 0.96 Inch I2C OLED
Using I2C SSD1306 OLED Display With Arduino Continue Reading
This tiny board designed to drive bidirectional DC brushed motor of large current. DC supply is up to 50V DC. A3941 gate driver IC and 4X N Channel Mosfet IRLR024 used as H-Bridge. The project can handle a load up to 10Amps. Screw terminals provided to connect load and load supply, 9 Pin header connector
50V – 10A Bidirectional DC Motor Driver Using A3941 Continue Reading
The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a subject are invariant over a range of light intensity. The three common-cathode RGB photodiodes
Color sensor achieves high dynamic range with auto exposure Continue Reading
You’re in a crowded street with many high buildings around you and you find your car position on Google maps is wrong. That’s usual, right? This is caused from (fake/distorted) GPS signals reflected from the high buildings around you which make your GPS receiver do some wrong calculations. So be careful don’t always listen to
2018 Will Mark A Milestone in GPS Technology with 30-centimeter Accuracy Continue Reading
This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I’ve designed a 24.5 x 50 mm PCB (2 on a 5×5 cm prototype) featuring MSP430G2553 and an adapter for a 8-pin
Magic Mote MSP430G2553 wireless sensor node with NRF24L01+ module Continue Reading
is a designer and manufacturer of low power, high speed Non-Dispersive Infrared (NDIR) carbon dioxide gas sensors. Recently, it has claimed a new speed record for its SprintIR6S NDIR CO2 sensor. The new sensor comes with response rates that had never been reached before by any other NDIR CO2 sensors. It can take up to 20 readings per second, and

The ppDAQC board from Pi-Plates.com is an inexpensive yet powerful solution for expanding the input/output capabilities of the Spark Core. And since Pi-Plates are stackable, it is a simple task to scale up the I/O capabilities of a single Core. All that is required for connectivity are the four SPI signals (signals A2-A5) as well as a
