To minimize the number of headers we need to use, we connect the display power lines to the power pins of the Atmega8 in-circuit serial programming (ICSP) header. The module is shipped together with an 8-wire cable, which I connected to Arduino with the help of the 2.54mm edge pin headers. The e-Paper screen module utilises a uni-directional SPI interface (CS, MOSI,SCK), two input control signals (RESET, DC), and a BUSY output signal. One of the bolts holding the Arduino board holds the sensor module, as well. We’ve started by drilling several holes in the tablet stand, and we then mounted all the parts on it. Sounding fun yet? Let’s get started! Starting with a prototype Electronics setup IKEA plastic tablet stand, for fastening all the prototype parts together. Wires, a USB cable, several plastic PCB standoffs, M3 bolts, and nuts. We’re using a DFRduino UNO R3 because of its colorful connectors 🙂 We’ll use a GY-65 module, though it may be replaced with a BMP180 ( GY-68).Īrduino Uno Board.
We’ll start by building classic project – a DIY barometer – and we’ll use:īosch BMP085 air pressure sensor. The device should be battery-operated, and it should be able to work for several weeks on one charge. This is more useful than a classic barometer, as pressure changes are more important to track than the absolute value. We’re going to build an electronic barograph, which is a device that measures atmospheric pressure and plots it on a chart to predict weather conditions for the next several hours. We’ve set ourselves an ambitious goal for the project. In this series of blog posts we’d like to explore how you can bring your pet projects to a more professional level and how IDEs like CLion can help you do that. They keep working on their projects as weekend warriors, treating them simply as small hobbies and side projects. But most of these Arduino developers don’t move forward.
Arduino is easy to get started with, and the experience of seeing the outcome of your coding efforts in a light blinking or robot moving is delightful. Many developers are playing with Arduino-based projects these days.
