The GVI Digital Remote Control for DSLR cameras represents an advancement over previous remote controls for the Canon EOS 450D. This remote utilizes the AVR Microcontroller ATmega328 and is programmed using the Arduino IDE. It serves as a tool...
This digital volume control has no pot to wear out and introduces almost no noise in the circuit. Instead, the volume is controlled by pressing UP and DOWN buttons. This simple circuit would be a great touch to any...
The circuit is capable of measuring frequencies ranging from 1.5 kHz to 500 kHz by connecting different capacitors, C1 to C6. It can handle a maximum frequency of up to 1 MHz. Transistor T1 serves as the integrator, with...
A dance pad consists of four pressure sensors (up, down, left, right). A USB controller has already been created for the dance pad, and the next step involves connecting the actual sensors. The intention is to pull the input...
Care must be taken to eliminate any stray currents from flowing into the current summing node. This can be accomplished by ensuring that all points surrounding the input are maintained at the same potential as the input. In this...
This circuit measures the distance covered during a walk. The hardware is housed in a small box that can be slipped into a pocket. The display is arranged such that the leftmost display, D2 (the most significant digit), shows...
