Basic Analog & Digital Parts Bundle
Analog to digital (A/D) and digital to analog (D/A) conversion make it possible for a digital device, like the BASIC Stamp 2, to both measure and control "real world" values such as voltage, light level, and frequency.
The BASIC Analog and Digital experiments introduce PBASIC commands for A/D conversion with resistor/capacitor circuits, interfacing an ADC0831 8-bit A/D converter, scaling analog outputs into meaningful digital values, analyzing time-varying signals, and using PWM as analog output.
These concepts are conveyed using potentiometers, LEDs, speakers, photoresistors, and pushbuttons.
- ICs: ADC0831 8-bit A/D converter, LM358 op-amp, and 555 timer
- Input: potentiometers, photoresistors, and pusbuttons
- Output: piezospeakers and LEDs
- Assorted resistors and capacitors
