Thanks to customer Mark, here is wiring diagram of the flow sensor/meter with esp8266, the key point is needing a 555 timer chip as a Schmitt trigger. Also the VCC voltage of flow sensor is 5V, and esp8266 is 3v3, a voltage divider is needed in the circuit. You can find the flow sensor...
We have one common kind of ammeter and two kinds of voltmeter in store, which are pretty useful in integrated into your system as a display, for example, it can show the battery level volts of your motorcycle, current level of your CNC machine, etc. This is the most simple two...
We have some new stepper motors coming soon, and we tested with arduino. To have a completed a understanding about stepper motor, we have documents a lot of information on this wiki page. You can fully understand how to recognize each pin of the motor, and how to connect them in phase frequency. This...
Here is a simple example about how to use the Ultrasonic sensor to detect objects. Parts List Arduino UNO R3 (I use the Adafruit mount) One (1) HC-SR04 Ultrasonic Sensor One (1) Red LED, One (1) Green LED Two (2) 560 ohm (Green, Blue, Brown, Gold) Resistors (more…)
The stepper motor has five leads, and we will be using both halves of the L293D this time. This means that there are a lot of connections to make on the breadboard. The motor has a 5-way socket on the end. Push jumper wires into the sockets to allow the motor...
1. Priciple Photocells are sensors that allow you to detect light. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they often appear in toys, gadgets and appliances. They are often referred to as CdS cells (they are made of Cadmium-Sulfide), light-dependent resistors (LDR), and...
We have a lot of NTC 10D-9 sensors and another similar sensors in stock, now we have a simple tutorial about how to use this one. You can get the NTC serials sensor here. First according to the datasheet, temperature and resistance is a function of the relationship. Rt = R *EXP(B*(1/T1-1/T2)) Of the above...
We have the TCRT 5000 sensors in stock, it's a pretty cheap $0.35 for 2 pcs, and easy to use sensors, you can find the product here. Now we found a detailed tutorial about how to set it up and use it from Bajdi blog, see the wiring and sketch below....
They are a lot of postures sensors are available on our sites, such as ITG3200、ADXL345、ADXL335、HMC5883L、MPU6050、BMP085、MMA7361, and these ICs are more used on flying control, now we did some simple test with the Bosch BMA180 module. Bosch BMA180 three axis digital accelerometer module has great performance than many others, it provides 14 bits...
