Serial Output to Processing Using serial.print from an Arduino to a processing sketch the variable resistor  / potentiometer value can be visually mapped to a continuous graph. It would be fun to see the same concept applied to a multi … Continue reading →

EMG Controller An ongoing collaboration with Ezer Longinus. Over the weekend we were able to get consistently solid readings from our EMG (Electromyograph). We rebuilt our circuit with the AD620 instrumentation amplifier and an OP97 operational amplifier using a schematic … Continue reading →

EMG Controlled Synthesizer In collaboration with Ezer Longinus:… we built an EMG (Electromyograph) circuit that detects the electrical potential of a muscle flexing. Using an instrumentation amplifier and an operational amplifier to amplify the week electrical signal in the muscle, the … Continue reading →

Working with analog output Servo Control / Tone Output

A basic intro to some electronic principles:

eMo (myoelectric – myomechanical sensor array) This fantasy device or concept prototype describes a device that might be able sense muscle tone and muscle movement in the larynx both while a user is speaking and silent. The device employs a … Continue reading →

Analog in; tracking changes with variables Beginning with a simple potentiometer connected to analog pin 0, I was able to variably dim an LED: Next I used the photo sensor instead mapping the sensor value so that the LED would … Continue reading →

Sensor Walk I plotted my course from my house in Greenpoint, Brooklyn to my studio… also in Greenpoint… about 15 min away… Taking note of different kinds of sensors along the way. I noted the usual suspects… ATM’s, motion sensors…etc.. … Continue reading →

First Arduino program Starting with the board layout and sample code provided… the red LED is “HIGH” or on and the green is “LOW” or off when the switch state is “0″ or off… when the switch state is “1″ … Continue reading →
