ESP8266 runs on 3.3v, and if you give it 5v from the Arduino, then it won’t work properly and it may get damaged. Connect the VCC and the CH_PD to the 3.3v pin of Arduino. The RX pin of ESP8266 works on 3.3v, and it will not communicate with the Arduino when we connect it directly to the Arduino. So, we will have to make a voltage divider for it, which will convert the 5v into 3.3v. This can be done by connecting three resistors in series, like we did in the circuit.

The module works to add both GSM features (voice call or SMS) and GPRS features. The advantages of these modules are the VCC and TTL serial levels that have 5V voltage, so you can directly connect it to Arduino or another minimum system with a 5V voltage level. There are so many GPRS\/GSM modules on the market which need to add a 5V regulator and level converter circuit, while SIM800L V.2 GSM\/GPRS module already has a built-in regulator circuit and TTL level converter on the board.\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eSpecifications:\u003c\/span\u003e\u003c\/h2\u003e\n\u003ctable style=\"width: 76.2004%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003eInterface Type\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003eTTL\u003cbr\u003eUART\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003eBaud Rate\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003eAdaptive (default), Support   2400-115200\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003eInput Supply Voltage\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003e5 ~ 20V DC\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003ePower Interface\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003e2.54mm Pin Header\/MICRO USB\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003eAntenna Interface\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003eASMA, IPX\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\" style=\"width: 23%;\"\u003eVoice Interface\u003c\/td\u003e\n\u003ctd class=\"attribute_value\" style=\"width: 49.2004%;\"\u003e\n\u003cp\u003e3.5mm\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eFeatures:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNetwork support: Quad-Band 850\/900\/1800\/1900 MHz – works on GSM networks in all countries across the world.\u003c\/li\u003e\n\u003cli\u003eTTL serial interface compatible with 3.3V and 5V MCU\u003c\/li\u003e\n\u003cli\u003eThe small size is suitable for all kinds of sleeve belt types and embedded.\u003c\/li\u003e\n\u003cli\u003eplaying card slot, convenient change mobile phone card.

In addition, this shield board has many pins, such as VIN, 3.3V, DIO, AIO, SDIO, UART, SPI, RST, and EN, thus can conveniently connect all kinds of sensors (e.g., temperature and humidity, buzzer, light, relay sensor, etc.)\u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"font-family: 'caviar dreams'; color: #b80000;\"\u003e\u003cstrong\u003eSpecification:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003ctable style=\"height: 327px;\" width=\"631\" class=\"shop_attributes woocommerce-group-attributes-layout-2\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\"\u003eMotor Power Supply Range\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e4.5V ~ 36V\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\"\u003eControl Power Range\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e4.5V ~ 9V (10VMAX)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\"\u003eLogic Operating Current\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e≤60mA\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\"\u003eDrive part of the work current Io\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e≤1.2A\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\"\u003eMaximum Power Dissipation\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e4W\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"attribute_name\"\u003eDrive Type\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003eDual high-power H-bridge driver\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"attribute_name\"\u003eWorking Temperature\u003c\/td\u003e\n\u003ctd class=\"attribute_value\"\u003e\n\u003cp\u003e-25 ℃ ~ + 125 ℃\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003cspan style=\"font-family: 'caviar dreams'; color: #b80000;\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eESP12 DEV KIT development board expansion module\u003c\/li\u003e\n\u003cli\u003eLead ESP12 DEV KIT all the features of pins: SPI, UART, GPIO, AI, and 3.3V power connector\u003c\/li\u003e\n\u003cli\u003eExtend two-way motor-driven, two-way direct-drive motor\u003c\/li\u003e\n\u003cli\u003eonboard power switch\u003c\/li\u003e\n\u003cli\u003eMotor power, control power separation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan style=\"font-family: 'caviar dreams'; color: #b80000;\"\u003e\u003cstrong\u003ePackage Included:\u003c\/strong\u003e\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cem\u003e1 x NodeMCU Motor Shield Board L293D for ESP-12E\u003c\/em\u003e\u003c\/p\u003e","brand":"Generic","offers":[{"title":"Default Title","offer_id":43607133913255,"sku":"RS1399","price":150.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0618\/9042\/9095\/products\/19719.jpg?v=1702155543"},{"product_id":"dt-06-wireless-transmission-module-dt-06-wireless-wifi-serial-port-transparent-transmission-module-ttl-to-wifi-compatible-with-bt-hc-06-interface-esp-m2-rs1458","title":"DT-06 Wireless Transmission Module DT-06 Wireless WiFi Serial Port Transparent Transmission Module TTL To WiFi Compatible With BT HC-06 Interface ESP-M2 - RS1458","description":"\u003cp\u003e\u003ciframe title=\"🔴 Add WIFI to 3D PRINTER (RAMPS 1.4 and other, DOIT DT-06)\" src=\"https:\/\/www.youtube.com\/embed\/5mM8FiSypJk\" height=\"700\" width=\"100%\" allowfullscreen=\"\" referrerpolicy=\"strict-origin-when-cross-origin\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" frameborder=\"0\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cspan style=\"font-family: 'Roboto Slab'; color: #b80000;\" data-mce-style=\"font-family: 'Roboto Slab'; color: #b80000;\"\u003eDescription:\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eDT-06 Wireless Transmission Module is designed and developed based on the E SP-M2 WiFi module which is extracted from the TTL, EN, STATE, and other pins.

Next, the circuit becomes a short circuit, and the LED gets sufficient current, and it will glow, and the buzzer starts to sound. If the circuit gets tilted so that the rolling ball doesn’t settle at the bottom of the sensor with the electrical conduction path, then the circuit becomes open. And led and buzzer should be activated until the switch ball doesn’t settle at the bottom.

For example, you can maximize range by increasing the transmit power and reducing the data rate, or you can reduce both for short-range sensor networks that sip battery power. At full power and with simple wire antennas, we can get messages from one side of a large office building to the other through numerous internal walls. In open air, you can reach 500 meters or more.
