It has been determined that the Hijack method for obtaining serial data from the Mindflex to the iPhone will likely not be utilized. This decision is primarily based on the availability of most components needed to construct a similar...
The circuit generates precision triangle and square waves. The output amplitude of the square wave is determined by the output swing of operational amplifier A1, while the ratio of resistors R1 to R2 sets the amplitude of the triangle...
This circuit is based on the State Variable Band Pass Filter, incorporating amplitude-limited regenerative feedback. The State Variable Band Pass Filter (SVBPF) is a versatile filter design that allows for simultaneous control over the center frequency, bandwidth, and gain. This...
This Arduino sketch is designed to recover ATtiny microcontrollers that have become non-functional due to incorrect fuse settings. It achieves this by placing the affected ATtiny into high-voltage serial programming mode and rewriting the fuses to safe values. The...
Generate sound or output analog voltages with an Arduino. This guide will demonstrate how to set up a basic digital-to-analog converter. To create a digital-to-analog converter (DAC) using an Arduino, one can utilize the Pulse Width Modulation (PWM) feature available...
This circuit generates a two-tone effect similar to the sound of a cuckoo. It can be utilized for doorbells or other applications due to its integrated audio amplifier and loudspeaker. The circuit is designed to produce a distinctive two-tone sound,...
