If you are planning on building your own 3D printer or a CNC machine, you will need to control a bunch of stepper motors. And having one Arduino control all of them can take up a lot of the processing and not leave you a lot of room to do anything else; unless you use a self-contained dedicated stepper motor driver – A4988.
This project describes building a fully-featured 12 V PC fan PWM controller. The design can control up to 16 3-pin computer fans. The design uses a pair of Dialog GreenPAK™ configurable mixed-signal ICs to control each fan’s duty cycle. It also includes two ways to change the speed of the fan: a. with a…
[bctt tweet=”A shield for the acquisition of 8 analog signals from the Raspberry Pi board.” username=”OpenElectronics”] A shield for the acquisition of 8 analog signals from the Raspberry Pi board, which can be stacked with other boards in order to, for instance, interface a big quantity of sensors, diagnostics, environmental control and IoT applications….
This open source hardware project has been created by developers at Bioblue. The ESP1 is capable of allowing users to control anything with their mind and includes an open source suite of Arduino development tools. Thanks to a lot of sensors the new hardware is capable of helping users meditate as well as boost overall…
How To Mechatronics has come up with a bender that not only twists wire left and right, but can rotate to create three-dimensional shapes. The 3d wire bending machine is powered by an Arduino Nano, which controls three stepper motors for wire manipulation via DRV8825 driver boards. A servo motor is also implemented in order…
A small wind generator which can be installed on a balcony or on the roof, capable of providing electricity to store in accumulators in order to power, for instance, domestic utilizers such as the video surveillance system when we are away from home and we cut off the main power. Second only to…
Catching wearable led lights, based on a custom Arduino Uno hardware with an accelerometer to trigger special light effects based on movement. Directly from the product creator, on his Kickstarter campaign: We are giving the community a fair & square open source tool and open source software to explore a new universe of performance microlights….
