    Hi there, I am back with another great and interesting project that is a Wireless Camera out of ESP32. Like ESP8266, Esp32 is also a development board with on board Wi-Fi but it has a greater number of pins and some more features additional to the ESP8266 or NODEMCU. In this project we are using an ESP32 chip or metal casing one PCB which is present on development board a Camera Model and some 3-D printed parts. Along this we have also used a SD card module to save the recording on the SD card and also transmit live surveillance on the server which is coded on the ESP32. We have custom designed the PCB for the ESP32 camera along with SD card module. the circuits can be found on the internet and can be designed easily. We have also used a led to provide light in the dark conditions. This circuit on battery and hence it is very important to make it power saving. We have tried to make PCB as small as possible with all the necessary components. No USB to serial IC is given on the PCB as ESP32 can be programmed via its Rx and Tx pins provided. And then when the all the components are soldered, we closed the circuit in the 3-D Model. The PCB was ordered on NextPCB and they provided me the best quality in short time, which is satisfactory. Ordering PCB online in various sites are a step towards developing our own circuit. NextPCB provides very easy😎 and fast delivery🚚 of PCB in different masks and paste with professional look. Also, they send you the picture of your PCB before shipping it to you, Now that very exciting…😃😃👍. #arduino #arduinouno #arduinoproject #arduinomega #arduinonano #arduino duo #ESP32 #Camera Module

    Hi friends, I am sharing another interesting topic in developing your circuits. The one which I am sharing with you is an NFR24L01 based circuit. The components used in this are an ATMEGA328P-AU, NFR24L01, Touch sensor and BME280 humidity sensor. For testing the circuits, the modules are best but for making a prototype these are very bulky so in this case we build a PCB especially for the task in this case this is the one. Mainly most of the modules are tried to be adjusted in it as the single piece but ATMEGA328P-AU circuit is made. No USB to Serial IC is designed in the PCB as a breakout for the FTDI connection is provide via which we can program ATMEGA328P-AU. NRF24L01 is a 1km range RF transmitter with the data rate of about 2Mbps, which is very good and useful solution for sending data via RF technology. BME280 is a Humidity sensor which provide accurate data of the water content in the air. Touch sensor provides a trigger for the circuit to send the data as it runs on battery and continuously running of circuit can drain the battery so it is good to trig the circuit on for the short amount of time and send the data. This would not be possible without the help of NextPCB and their extreme good and fast service of provide custom PCB on time.

  • ESP8266 Touch Sensor

    Hey guys, today I am going to discuss about some of the most useful IC, Development Boards and Sensor. One from each of them are AMS1117 3.3V regulator IC, ESP8266 Board (full complete with adapter) and Touch Sensor. So, let’s talk about each of them, as I have told earlier in my previous post about different type of IC packages this is of SOT-223. So, it is vit difficult to solder on a piece of perfbord as it is a SMD type, so dip converter is the best solution of this problem which I have discussed in my post. Next moving onto Touch sensor is built out of several smd components mainly consisting of TTP223 IC which is a Capacitive touch sensitive IC, it actually detects the voltage on the touch pad and monitors it. when we touch the capacitive touch pad a small amount of voltage drop is developed on the pin of the IC which is detected, and IC makes the output pin HIGH or active. Now it’s time for ESP8266, I am sure that many of us have done work on ESP8266 or NODEMCU but the whole development Board is not the ESP8266 but only the metal casing PCB is the ESP8266 Board. It consists of a WI-FI chip and an 4MB memory in very small smd package and left-over pc is the programming adapter which consist of USB to Serial converter IC like CH340G or some other like it. It also consists an additional button other than reset because as it is a Wi-Fi chip you can flash a custom Firmware onto it by pressing down the flash button and loading firmware onto it. So, this was the some of the important things which are used in most of the IOT projects. I hope you like it and NextPCB helped me out to make my Projects and good looking by developing PCB’s for my projects.
