Working with LED Dot Matrix display and shift registers.
Completed soldering of 11x5 led dot matrix
Did a lot of googling and learned about maker culture.
Couple of weeks, I was working with ESP8266. to implement basic device registration process for IoT product. Finally I’ve cleared all my challenges. Learned MQTT, spiffs, and lot of string handling functions 😂. All this done by using esp-idf.
Watching Google iO 2021
Went for an outing:partyparrot:
Got hardware from Hackster.io
AVR-IoT WG Dev board combines ATmega4808 AVR MCU, ATECC608A CryptoAuthentication and ATWINC1510 WiFi network controller.
Very easy to connect with Google cloud.
Yaay:yay: this is awesome. :ultrafastparrot: Big Sur
Completed soldering of my PCB. Don't look that Messy wires😅 :hardware:
Making a GSM Notification for air blower. :hardware:
Watching videos of BMS(Battery management system) for an upcoming project.
Accidentally connected in wrong polarity. 😑
Within 3 seconds :fireball: 😑 😑
Done some readings to choose a motor for rover :hardware: hardware
Pair coding is the best way to fix code :partyparrot::zoom:
Made some circuit diagram using fritzing for a friend.
Found this pic from gallery. This is a board used to detect falling. :hardware:
http request using ESP8266
At last OTA worked :ultrafastparrot:. The pain is, the solution was verrrrryyyyy small. Just need to change one directory. But this one confused me for 3 days😐
Spend lot of time on Azure Sphere starter kit. But no way:annoyed:. They don't have Mac OS support. So, I installed Linux on Virtual Box and tried. But device is not showing its OS version. Also, can't login Azure account from CLI. Showing some errors :angrycry:
I was working on a project with relay module and Arduino. After soldering I found a problem in relay module. Sometimes it's freezing microcontroller and reset. It was really annoying. I faced same issue in many other projects. Today I decided to read the whole Google search results. Finally I found the solution from a forum. Later found the same in datasheet. Actually relay module is not completely isolated. we need to remove the jumper and connect external supply for complete isolation. This was written in its datasheet. But reading whole datasheet is a boring thing. But it includes many useful stuff. like developer documentation. anyway even if it's a small thing, it was great learning for me. Now I can work with relay without any fear.
Soldering completed :hardware:
Arduino pro mini and RTC is here :hardware:.
Deployed my python Bot 'Minnal Murali'. Spend lot of time on heroku. Bug at last found a blog post, Corrected my error simply by changing file name and Procfile 😂 Checkout my project on GitHub: github.com/rafitc/Minnal-Murali
Completed my python Bot "Minnal-Murali". It will send e-mail based on typeform responses. Planing to use in our club for sending event confirmation e-mail to attendees.
e-mail automation using python.
Remote bug fixing :hardware: TeamViewer, Arduino
Reading documentation is a huge task🥴
After several Google search and Youtube search, realised that there is no video/blog/medium/hackster/instructables for me. At last I decided to read documentation. 🤐 🤐
Some random things using TinyRTC with Arduino :hardware:
Learning Firmware Over the Air(FOTA) of ESP8266 RTOS :hardware:
Got a AVR IoT kit from microchip for hackster.io contest. :hardware: Very excited to make something new.
