This instructable will guide you to glow an LED using a touch sensor which means that the LED will glow when you touch on the probe of the sensor.
The project uses the Mediatek linkit one connected to a touch sensor and an LED. As soon a touch is detected, the output goes high which is detected by linkit one thus the LED glows.
So let’s begin with this project………
Step 1: Parts Required
The following parts are required to make this project:
– Linkit one
– Battery
– Breadboard
– Touch sensor
– Transistor
– LED
– Jumper wires
Step 2: Connect the Battery
The first step or the easiest step is to connect the battery to linkit one. Simply plug it to it’s socket.
Step 3: Connect the LED
Next step is to connect the LED. You can follow the images provided above. The digital pin that you need to use is- pin 2.
Step 4: Connect the Sensor
Connect the touch sensor to linkit one as per the following:
– Vcc ——————— 5v of linkit
– Gnd ——————— Gnd
– Out ———————— A0
Step 5: Upload the Code
Upload the code provided below to your linkit one. The switches should be in SPI, USB and UART positions.
\\
void setup()
{
pinMode(2, OUTPUT);
}
void loop()
{
if(analogRead(A0) > 600)
{
digitalWrite(2, HIGH);
}
else
digitalWrite(2, LOW);
delay(100);
}
