This is a useful tool that allows to connect Personal Computers or a microcontroller in wireless networks using the famous XBee wireless modules. Connection is done via USB port and when you plug the board into the USB port, the PC system will recognize it as a serial VirtualCOM Port (VCP) which will realize the communication with the XBee module.
This shield allows an Arduino board to visualize informations on an attractive LCD display with white text on blue backlight. 5 push buttons make possible the implementation of projects where menus are visualized on the LCD display and selections are made by the pressure of the buttons, each of them numbered from 1 to 5.
This is an Arduino compatible module that provides an easy way to control high voltage thanks to 4 independent channels equipped with photo-coupled mechanical relays preassembled on the board. The maximum switching power is 1250VA AC or 150W DC.
This is a small circuit that allows to reverse the voltage applied to the load simply acting on a switch.
This carries an infrared LED and phototransistor pair. The phototransistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0V and +5V as a function of the reflected IR.
This is a basic 16 character by 1 line display. Black text on Green background. Utilizes the extremely common SPLC780D parallel interface chipset. An LED backlight enables optimal viewing in all lighting conditions.
This is a basic 8 character by 2 lines display. White text on Blue background. Utilizes the extremely common SPLC780D parallel interface chipset. An LED backlight enables optimal viewing in all lighting conditions.
