Dear fellows,   I want to share with you some info about a neat steeper driver board we designed, for driving two or four stepper motors (by stacking two boards) using Arduino UNO (& friends). This neat shield can be used for making pan and tilt mechanisms for cameras, small CNCs, 3D printers you name it. This shield has a free downloadable example software (INO) and a video to demonstrate some of the capabilities. The driver chip used is L6470 from ST Microelectronics, a complex moti ...
Dear fellows,   We are proud to present a shield that we make, mainly for receiving FSK (and OOK) signals from sensors but not only. The shield comes with a duck antenna and demo examples.    FSK signals at 433MHz are very commonly used by consumer electronics devices including weather stations, power consumption meters, security systems, and home automation controllers. The RF transceiver used is RF12 from Hope Electronics, this means that the shield is using SPI. The advant ...
