The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...
Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
Arduino OPTA and Arduino OPTA DIGITAL shares an I2C bus and a sort of UART bus ( OPTA Tx is wired on all OPTA DIGITAL Rx). Arduino OPTA has a PIN that goes toward expansions (other Arduino Digital), ...
This project simulates a two-hand safety interlock system implemented on an Arduino Opta PLC, inspired by industrial safety control logic. The system requires two push buttons to be pressed ...
In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to analogue converter is needed. The machine uses a ‘grbl’ controller, which has an ...
