Now block can be added to reduce the speed of value changing and you can see it clearly.Īttached -mCore main control board light sensor diagram fluorescent lamp), you can see the rapid change of sensor values (the script is running fast and the values vary with the ambient light in real time). Light sensor value range: 0~1000, exposed under sunshine (> 500), evening (0 ~ 100), lighting (100 to 500).īlocks can ensure the light sensor display real-time values, or only the start-up values are displayed continually.Īlso, if the ambient light is not stable (e. While the program is running and debugging, it is often required to collect real-time sensor values to help us understand the environment light, sound, distance and other information. Sensors are used to detect events or changes in the environment and send information to the electronic components of other electronic devices. Use to show the value of the light sensor in a way where a stage character (a panda) speaks the value out.īy repeating, to allow the values of the light sensor be displayed continually. Use the “when the green flag is clicked” block to start the program and perform online debugging. You can use either a battery or FTDI+USB for powering the board. Here we are using Arduino Pro Mini as our microcontroller. The below circuit and code is for demonstrating basic working of TEMT6000 Ambient light sensor. Other sensors use the same method to collect data.Īs it involves the stage show, it is necessary to use a Usb cable to connect the computer with the control board via a serial port rather than burning the program to the Arduino board. BH1750 is a 16-bit digital ambient light sensor developed by Rohm Semiconductors which can accurately measure the light intensity over a wide range. TEMT6000 is used as ambient light sensor for display back light dimming in mobile phones, Notebook computers, cameras etc. Connect one end of the photoresistor to 5V. Repeat the previous step for the red LED, connecting the LED to pin 7 on the Arduino. Connect the short end of the LED to a 100-ohm resistor, then connect the other end of this resistor to GND. Drag the map block you made earlier into the 'set pin' blocks 'to' field to write the adjusted number to the LED pin using PWM. Back in the Output category, drag out an analog 'set pin' block, which by default says 'set pin 3 to 0.' Adjust it to set pin 9. In this case light sensor, for example, explains how to capture sensor values and display them in real time. SEN0172 LX1972 ambient light sensor SEN0043 TEMT6000 ambient light sensor SEN0175 UV Sensor v1. Connect the long end of the blue LED to pin 8 on the Arduino. In the first slot, drag in a sensorValue variable block, then set the range from 0 to 255.
