Summary of How To Interface a CDV 700 Geiger Counter to a PC Using an Arduino Video instrucitons
This article details Part 2 of a project interfacing a CDV-700 Geiger counter with a PC via an Arduino Uno. It explains the setup process and provides specific C++ code to read radiation counts from the device using an interrupt service routine on pin 2, transmitting data via serial communication at 9600 baud every second.
Parts used in the Interface CDV 700 Geiger Counter Project:
- CDV-700 radiation meter
- Arduino Uno
- PC
- Cable or wiring for connection
How To Interface a CDV 700 Geiger Counter to a PC Using an Arduino (Part 1)
The second part of our video series of our project to interface to a CDV-700 radiation meter using an Arduino Uno!
How To Interface a CDV 700 Geiger Counter to a PC Using an Arduino (Part 2)
Code:
A video on our project to interface to a CDV-700 radiation meter using an Arduino Uno!
Here is the code mentioned in the video:
int count = 0;
void setup() {
Serial.begin(9600);
pinMode(2, INPUT);
digitalWrite(2, HIGH);
attachInterrupt(0, count_isr, FALLING);
}
void loop(){
int i;
delay(1000);
i = count;
count= 0;
Serial.println(i);
}
void count_isr(){
count++;
}
- What is the purpose of this project?
To interface a CDV-700 radiation meter with a PC using an Arduino Uno. - How does the code initialize the serial communication?
The setup function calls Serial.begin(9600) to start communication at 9600 baud. - Which pin is configured as an input for the Geiger counter?
Pin 2 is set as an INPUT and enabled with an internal pull-up resistor. - What type of interrupt triggers the counting function?
An interrupt is attached to pin 2 that triggers on a FALLING edge. - How often does the loop transmit data to the PC?
The loop waits for 1000 milliseconds before printing the count value. - What happens to the count variable after it is printed?
The count variable is reset to zero immediately after being stored in a temporary integer. - Does this article cover hardware assembly steps?
No, the text focuses on the software code and video series context rather than physical assembly.
