If I have a simple microcontrol, say 8 pin PICAXE. Could I use it to read the voltage going through a circuit directly? And can I output varying voltages?
Click For Summary
Discussion Overview
The discussion centers around the capabilities of a simple microcontroller, specifically an 8 pin PICAXE, in relation to reading analog voltages and outputting varying voltages. Participants explore the potential for measuring current and controlling devices like solenoids or motors based on that current.
Discussion Character
- Technical explanation, Conceptual clarification, Debate/contested
Main Points Raised
- One participant inquires about the ability of the PICAXE microcontroller to read voltage directly from a circuit and output varying voltages.
- Another participant notes that some microcontroller chips include ADC (analog-to-digital conversion) and DAC (digital-to-analog conversion) resources, while others do not, suggesting the need for more specific information about the microcontroller in question.
- A participant expresses interest in using a specific product to measure current through a wire and adjust power to a solenoid or motor based on that measurement.
- It is mentioned that the PICAXE microcontroller has built-in ADC capabilities but lacks DAC functionality, although it does have digital outputs that might allow for control via pulse-width modulation.
Areas of Agreement / Disagreement
Participants have not reached a consensus on the capabilities of the PICAXE microcontroller regarding outputting varying voltages, as there are differing views on its available features and how they can be utilized.
Contextual Notes
The discussion highlights the limitations of the PICAXE microcontroller in terms of built-in DAC resources and the reliance on external methods for achieving desired voltage outputs.
