Hi Alan,

I purchased a stair light kit in 2016 from you and it was working fine until the last month. It seems to me that the IR receiver and transmitter is not functioning properly so that they need to be replaced. Do you have these components available and can I get it shipped to Australia or Sri Lanka?

i looked to your design of the stair lights .
my question is , is the schematisch sigrid . so can i get the info how you made it ?

Hi Alan
i need to design an experiment using an lm35dz temperature sensor to determine the sensitivity of the sensor

Can you contact me for snowrobots?
I live in Norway and want to test it in my city so if you have contacts about this issue please contact me on

Respected sir,

Myself Manas Bose, Sir I am working on a project, where I have to control a stepper motor step control with the help of a potentiometer, and arduino the sir I have wrote a skech with the help of a friend attached herewith, it is working fine.

Sir now I want to make this thing wireless, sir I want to use 2 arduino and 2 xbee, on sending side a arduino, xbee, and a potentiometer will be there. On receiving side a arduino, xbee and a stepper motor will be there. Earlier one setup I made with servo motor.

Sir, I and my friend don't have adequate knowledge of c ++, I hereby request u to kindly help
In the coding, or at least if u can throw some light on it.

Hope to be favored please
Thanking you

#include <Stepper.h>
int current_position = 0;
const char direction_pin = 2;
const char step_pin = 3;
const char pot_pin = 1; //analog input 1
void setup()
pinMode(direction_pin, OUTPUT);
pinMode(step_pin, OUTPUT);
pinMode(pot_pin, INPUT);

void loop()
int readvalue = analogRead(pot_pin);
readvalue = map(readvalue,0,1023,0,1151);
if (readvalue > current_position)
current_position += 1;
else if (readvalue < current_position)
current_position -= 1;
}//end of loop

void step_motor_forward()
digitalWrite(direction_pin, LOW);
digitalWrite(step_pin, HIGH);
digitalWrite(step_pin, LOW);

void step_motor_back()
digitalWrite(direction_pin, HIGH);
digitalWrite(step_pin, HIGH);
digitalWrite(step_pin, LOW);
