The hacked Arduino board is old that it has the ATmega8 instead of the ATmega168 and the ATmega bootloader image has not been updated for the auto-reset. Interestingly, the ATmega168 bootloader code ...

how and why was that working, the modified circuit design. 8u2-burn.bat, to brun Arduino-usbserial-atmega8u2-Uno-Rev1-PID_0x0001-xiaolaba.hex to the chip, burn_arduino_com8.bat, to burn 328p.hex to ...

Since the 555's output is tied to the Arduino's reset line, this will reset the system. When the Arduino sends a heartbeat to the watchdog circuit, the heartbeat line is set to a low output, aka GND.

But this time, in this circuit we are not only turning On and off lights based on light conditions but also varying the intensity of light according to outside light conditions. Here we have used LDR ...

The Casio SK-1 keyboard is fairly well-known in the “circuit bending” scene, where its simple internals lend themselves to modifications and tweaks to adjust the device’s output i… ...

It also has a reset circuit which monitors the output voltage and provides a delayed open-collector reset (with internal pull-up resistor) to the supplied microcontroller at power-up and also when an ...
